Hi sirobb ive Just bought a d5 Volvo S60 and it has this problem. Ive been looking through your videos you have posted and mine has most of the problems you have put up. Your videos have help me a lot and saved me money and headache from the wife as she thought I bought a lemon. Thanks again please please keep posting these realy helpful videos.
OMG man !!! I was REALLY WORRIED about my D5 engine, because of this sound. Now, at 1 am, searching about the issue, I have found your video - and yes , I can tell that this was my problem. Thank you very much!
Hi to you all Volvo owners! First of all i have to say that SirRobb is the Superman of old Volvo. Thanks to him i discovered why my old d5 made that strange noise when pullin off the oil filler cap. I can confirm that is a vacuum related issue. so, i noticed that when pushin hard the brake peddal the noise stoped. so in my case it was the power brake booster cause is related to the vacuum pump. the car was brakin just fine but sometimes the return of the brakin pedal was kind of slow followd by some air leak, like a wistle. Hope this info is usefull for those who didnt find anyother leak on the engine monunts or vacuum pump. Thank you SirRobb
Johnny Depp you mightve just solved my problem with the vaccum leak Ive literallt replaced all the lines and mounts but still get the noise. Going to try this tomorow too see if it works
Hi Johnny, I have just found a similar knocking noise after pulling off the oil cap of my C30 D5. It sounds very similar to this video but higher pitched. Can you remember if the sound from your engine was higher pitched? Would I be able to contact you and send you a video? I still need to check the engine mounts the same way this video suggests and also push the break pedal hard like what you did and see if the noise stops. Cheers.
This is What i call superb info from an Expert in my opinion, You have a lot of videos and i like them very much AS this is important and simple info, No volvo Dealer will tell you, at least not here in Norway (NoWay🤣) Keep up the good work!
Had exact same problem, went on YT found your video SiRobb and everything is sorted now. I just had to comment beacuse you helped me effectively and quickly diagnosed this! Much much appreciated for your kindness and that you are uploading such videos! 2 weeks ago I was after W124 MB pre 1993 but I couldn't find right example so I changed my mind and luckily my Gold D5 2002 S60 with 65k milage came up on Facebook marketplace and I decided to give a go beacuse my head always turned around when I saw these cars and used to always liked them : D Same as 7xx series, 9xx, 850, and pre 2002 V70s. My car was bit neglected but I am giving her proper care now. Last week front and rear engine mounts, full service plus carbon cleaning, front brake pads, central exaust leak welded, Injector seal replaced, turbine refurbished and wheel alignment done. That's so far. I am gonna check all suspension as a next step and replace gradually everything which needs to be addressed. Feel good about that! I've got one struggle with interior though and it's driver seats. Because it's Velour ( I didn't want leather interior) the seat is worn and there are holes already in a stichings. Anyway this as well will be done! They such a great cars. They have this feel of 90s/80s and when you driving one no any other from any new ones brands will make you smile and there is feeling in you that you actually never will go for modern beacuse is there any pleasure to drive a soulless machine ? : ) I like as well idea that these cars proper maintained lasts forever not needing to be replaced and people by keeping them developing some sort of feelings towards them. That's true friendship beetwen the man and the machine isn't ? SiRoob have a nice day tomorrow and wish you all the best! Cheers!
You are so right about so called experts I know this through bitter experience. Recently I took my 2007 D5 to a workshop fir a crank shaft seal replacement, a 7-8 hour job listed in Volvo schedules of work. The workshop took the whole engine and gearbox out, split the two, replaced the seal, replaced the whole unit resulting in a car that would not run properly below 2k revolutions. 24 hours work, a car unuseable and they wanted £1400, and I bought the seal.
I removed the brake booster vacuum hose from the vac pump and this popping noise STOPPED! Stick my finger over the pump inlet and the popping starts again. How contrary is that. Very good videos and much appreciated.
@@sirobb That does make sense, thank you. I was having slow start issues with my xc70 and tracked back to the ECU not seeming to transmit a signal to glow plug relay, also the original volvo glow plug connectors were really craply done so I have just made a whole new glow plug relay and distribution system controlled by a NO micro push switch mounted on plastic panel near gear stick. Also noticed that when the coolant temp switch is removed, the car is fooled into thinking it's very cold so opens up fuel rack etc and starts immediately (sort of puts it into beast mode). So I have run that to a NC momentary switch next to the glow plug relay witch. One way or the other, that get it started! These are so well built, but sometimes a bit too clever so we have to rethink the electrics. Before I got it the history shows a fortune spent at volvo garage to fix glow issues, fab remedies like wrapping tap around the glow connections!
Today I have tested this and had the same noice and same fix you show... But im comcern of your video I would recommend you to check your PCV that not excists and your camshaft Thank you for your Videos, Mate...
Hi sirobb ,kept most of your vids,very helpful,been in motor trade 55yrs,got this xc70 countryman diesel to sell 2 yrs ago with 229k on it one owner war and peace history ,now 235k as I couldn't part with it as it does every thing it comfort and ease,one thing I've had a go at to no success,engine check message,lack of power,checked most thing gave up taking turbo of to degrease the vanes as it looked a right job, I just drive and when it does it I flick of the ign and on again and carry on driving,worse when cold so I don't Rev it to much then,had egr off etc cleaned it all,inc top rocker box,some crap in there,thank gig for
I own an D5 with engine damage cause I've a good engine to replace. Thr engine runs and To hear was this Noise (thanks to you i knew what it is) and a metallic hard noise from a defect top engine mount. a detective Glowplug prevent from a good start. So the previous owner had been informed by the workshop that engine damage was imminent and he sell it cheap. It's a shame what workshops tell his customers for a bullshit for the next order. Ok the dpf was full cause glowplug failure but I repaired it all and have a very good in shape v70 phase 3 for much less than good in state running cars.... Thanx again
Hi SiRobb Just wanted to thank you for the well presented & informative videos. I have recently acquired a V70 D5 and as a retired heavy truck fleet engineer I guess I would eventual get around to learning some of the stuff you have presented in such good tutorials. Very impressive. Thank you Dave
It's 3 plus years since I previously thanked you for your really impressive tutorials Simon and you continue to do some great stuff. Just wondering could you direct me to anything you have experienced on changing the Volvo HU-850 radio with another of same model coming from same year V70. There appears to be some sort of software mismatch, CAN bus issue and proving to be a nightmare. I don't have VIDA or DICE but would buy if a code change is possible. Dave
Just subscribed because you've done a great job with this diagnostic...Have been running Volvo XC90 D5 for the past 7 years (on my third car now) and these are the best tips. great man, thank you
I have an XC 70 that loses power every now and then. Lots of parts been replaced but still have the same problem. Anybody come across this problem before had full service and changed the cam belt but still the same intermittent problem any ideas please
Thanks for this, that was really helpful. I didn't realise my engine wasn't supposed to be as loud, and had really bad power loss on my motor coming home from holiday! Going to try this tomorrow and order new mounts
Thank you... You are a Legend. 😉 Everyone on here calls themselves an expert 😂. Even the "technicians" At my local main dealer couldn't diagnose this noise for me. I did as you do in this video and problem solved. My engine mounts are fine but the vacuum hose had come disconnected... Probably the last time an "expert" had his hands under the bonnet.
Once again SiRobb does the job! My D5 is doing this and I know it is the mounts and I have a vacuum tester. But I actually think that pipe is not connected to the control valve on my car. I must check when daylight arrives!
Thanks for this video, had a very rare limp home mode issue and suspected a vacuum leak straight away and tested for this noise and have it, so luckily an easy fix
I also have a vacum issue with my D5. The noise doesn't go away even if I block the connection on the vacum pump itself. May this be caused by a leaking brake booster? I already have changed the O-ring on brake boosters plastic connector.
Another brilliant video, I decided to check to see if mine had the popping issue and it dose, all engine mounts are new. I’ll be watching your other videos to try and locate the source of the issue! Thanks very helpful stuff
Thanks for the video. Had the same issues with the sound coming from the filler hole. Also people said it was a crankcase ventilation problem but ventilation was all clear... Gonna check the vacuum hoses tomorrow. I already blocked the engine pads a long time ago so it could me the lines to the turbo.
Mate your a star. I just bought a v60 es 63plate and I've not had a Volvo before. Lovely ride o ly done 60 miles but theres a hissing noise like a turbo leak or inter cooler leak ect Dose seem propper sluggish but I've been that busy mot had ti e to look. I just tonight opened the oil filler cap and heard this load popping noise and my neighbour who was 50 ft away said "oh that's fucked get rid of it... "
So smoke is perfectly normal for a d5 pheww. I've be maintaining mine like a crazy man. I haven't got the excessive popping noise but a bit of smoke from the oil cap. I'm running miller's 5w40.
hi my d5 makes this noise but when i bloke the brake servo hose and the vacuum hose from governor, the popping noise stops completely. dose that mean my brake servo is faulty. no leak on vacuum pump. i blanked the engine mounts but noisy still
I have same problem on my s80 2011 D3 engine and i asked to volvos service this problem but they said that this is normal ... i gonna test it if d3 have same vacuum system like p2 volvo. Thanks for great video !!!
quick ? Rob, why do engine mounts need to be supplied with a vacum? So interesting, and forgive me if it`s obvious but i am not very mechanically knoweldgeable to be quite frank. Thanks for all your videos, i have just bought a d5, 2006 model, and seeing this wealth of info you have shared with us has helped me decide to purchase this car.(my 1st Volvo!!) Still gotta go fetch it, so have only done a test drive thus far, but what a car is all i can say for now. :)))
thanks man, you are great to bother replying to me. My son in Germany googled it the other day when I was chatting to him and.I'm happy to hear he is right!😊 Was wondering how long I can let it go on for, any danger to the turbo I hope by leaving it for a while? These motors fuel economy is allegedly 6,5 l per 100km(i think-its the d5) but with a well serviced engine and driving responsibility(mellow acceleration etc, I am an experienced driver) I'm wondering what kind of fuel economy I should expect. Any idea here Rob? (It might be a good indicator of excessive vacuum leakage from those engine mounts..) No worries if its asking too much, but if you have some idea, I'd appreciate some insight here. Cheers Rob.
Hi SiRobb, I have a XC70 D5 2005, got the same noise when opening the oil filler cap, WIll try to remove the hoses to the engine pads, I also agree it is a vaccum issue, my question, I was probably stupid when I blew compressed air into the hoses after removing the hoses from the TCV. Do you think I have damaged something with the compressed air. The turbo is not working anymore but that could be linked to being clogged with oil sauce after the oil cooler broke. Thx and best regards from a Swede living in Germany having three Volvos. XC70 D5 , V70 GLT 1997, S80 V8 2007 with Heico sport exhaust.
Too bad your car seems not to have the parking heater installed. This component fails all the time on the up-to-2006 models. A repair and disassemble walk trough would be fantastic. Your video's are great!\
Absolutely brilliant tutorial videos Si, Rob, SiRob. Imo the very best Volvo tutorials on RUclips 👍👍👍 I have just bought a XC90 with 105K miles with enjoy popping, now I know it's nothing really, the other thing is a rattly noise from down by pulleys on idle but when rev up it goes, I was thinking it could be air con pulley? Can I replace the pulley? Cheers.
Lovely, thanks so much! And while the Volvo world might be small - you are one of the great..=*^) I'll check out the other video right now. Hope to run into you some time and be able to say Thanks face to face..=*^) Thanks again!
Did think my self omg hes right. Is it out of oil I thought. Then couldn't find any dipstick!!° I'm an engineer an I've stressed out about this all night untill I've seen your vid. I think there is a few problems with the car but I'm now understanding what is going on without having to ask a main dealers help.. expensive and clueless
WOW WELL DONE FINDING THIS KNOCKING NOISE PROBLEM !!! I have bought 2008 xc90 d5 for my dad 3years ago with this noise. I knew then that it was something to do with vacuum but could not find what. Ever since it bothered me but now I know what it is and can fix it. Thanks
Hi Robb, interesting video. I think in 38yrs of driving I’ve never undone my oil filler cap whilst the engine was running. Of course I now have on my recently purchased winter ride 04 V70 D5 😱 the popping sound is there on take off, car drives well otherwise. Hopefully it can wait until the Spring when my Summer car comes out again.
I have this issue as well as many others apparently. I found that unplugging the electrical connector on that valve closes it an the popping goes away. Since you call it Turbo control valve, does it do anything else than provide vaccum to the motor mounts? I am thinking that I will leave it unplugged until mounts are replaced, good idea? Thanks for this good information!
So I have watched your video, and found I also have the “popping” issue. However, when I block the valve off like you did, the pop continues and doesn’t change tone in any way. Soo, what could it be 🤷♂️🤦♂️ D5 XC90
Just got a d5 & thought I'd test this myself but someone has disconnected both the hoses from the mounts. I have this noise but can't figure out where it's coming from if both mounts have been disconnected. No fault codes on the car when driving it does make a turbo noise I'm guessing that's normal though
Thx sir for this aweaom vodeo!I have on my s69 D5 low acc and issues over 2500rpm,and the error code is 6805.All happen ed when in one workshop cleaned my egr valve!
Hi ! Thks for your videos . I have D5 2008 on XC70 , i have popping noise like the video , could be the hodraulics engine mounts ? Or mi car dont have. Thks you very much.
hi Sirobb I am a french, the youtube translation is not good I can not understand. I have a d5 and it makes the same noise I would like to know what was the solution to the problem. Your videos are a great help to me! thank you very much!
Got the motor service light coming on, and a rough wobly engine so I thought change the engine mounts. Tried the test with the hose to the control valve and still the same noise. So I'm not sure what's going on there
Ok so I’ve got it the other way round. When I hold my finger on the vacuum pump I get the popping noise. But when I let go it is quieter. I’ve got a thudding when it’s idling and other people have said it’s the mounts but it’s the opposite to this video
OMG I HAVE THIS!😧 I have had loads of V70’s but never came across this before🤷🏼♂️ I am an engineer and annoyed i couldnt find what it was i have never heard of VACUUM ENGINE MOUNTS! I need to change my lower steering UJ before the MOT as its starting to feel ‘vague’ so its that. When its up on the ramps ill change the mounts. NEVER heard of any manufacturer doing this before, totally new to me 🤷🏼♂️ CHEERS SIROBB I was thinking big ends but the engine PURRS and is very pokey so not that?
@@sirobb I just found that after posting the comments x) Thanks a lot for all the D5 info it's been a huge help in understanding how my car works and all the possible failure points, they can make many miles** but must be well maintained and you've helped ever so much! :) Volvo for life!
Hi. Great videos! I've tried cleaning the tcv an blocking the pipes all the way down to the pump. Blocking the vac pump wont help. It seems as there is a lack of vacuum. Testet it with a vac gauge. The vacuum comes in pulses, and it wont build up, it just flickers. Removing the maf makes it even worse. Thinking its the vac pump thats broken. Just wondered if there are any other things I can check before I get a new one? Can't see how the maf sensor has anything to do with vacuum the pump produces? I have the EURO3 Christopher
See my video here ruclips.net/video/0zsIa4Y2Tcs/видео.html and put the vacuum tester directly onto the vacuum pump. If the needle flickers and doesn't stay stable, the vacuum pump is faulty or the vacuum pump seals. Buying a used pump should be quite cheap because they are very reliable so not in high demand.
Can you explain why the engine mounts me CREATE noise in the oil filler cap ? Is the breather operates on the same vacuum system ? Sorry for my english
Hi Sirobb! i had the same problem. the popping went away by isolating the rear mount- changed the mount and the popping is still there. The line itself holds preassure. Im stuck now. One volvo garage told me that they have seen many euro 3 engines that have this popping that goes away by isolating the rear mount even when the mount itself is fine. Is that true? is the rear mount supposed to leak some vacuume?
@@abood_abtv4203 In the end i ended up swaping out both vacuum actuated mounts and vacuum hoses and the vibration in cabbin got even worse- transmissions tarted touching the subframe at times so another independent garage swapped out all 3 rubber mounts (for Lemforder) since they all were perished and only then found out that the new "Febi" vacuum mounts were both shot (assuming- defected from factory or just designed badly") and leaking oil when removed for inspection once again. Got "Lemforder" ones and all the vibration and popping went away.
I've got exactly the same noise on my D4 2.4 diesel. Very loud popping noise but I don't have a turbo on the car? Probably a vaccum leak by the sounds of it but I can't find it
Hi ,Robb my name is Vas, I have volvo xc90 d5 2005 ,I have problems with my volvo is running really rough, is popping like in the video I have checked the turbo control control valve
SiRobb,thanks for this and the other videos. I just find this noise in my s60. Temporary fixed for a screw. Need quickly changing the mounts or enough few weeks later? Thanks
thats told the know it alls, i think the easiest way to deal with volvo's is to keep on top of them by regular maintenance a servicing, they do need looking after..
Hello @sirobb Aside of the popping noise, the noticable engine clicking noise is perfeczly ok? Or it might be problem with hydraulic lifters? Thank you!
So on a 185, and the noise doesn’t stop when you block the pipe the noise doesn’t go. Unless you rev the car up, does this meant it can only be the pump? Cheers
Sirobb do you actually know how the loss of vacuum is causing that popping sound. Obviously, it is a vacuum issue and my D5’s popping noise is even louder than yours so I am just trying to understand what exactly is popping in the engine. Many thanks!
Wow just started hearing this slightly every now and then I have the 2013 p3 205 hp twin turbo is it possible for this engine or are all d5 s basically the same just different turbos etc
Exact same symptom on my Euro 3 D5. Is this something that would be harmful for the engine to drive with over longer period of time, or is it just a concern or not while idling? Runs like a train, but I’ve started to feel signs of a bad engine mount when I accelerate and then let go of the throttle quickly (just to diagnose if it was the mounts or not)
Mine (XC70 D5, 2010) have the same problem, with 130k km on it. Too, after 1800 revs, a great amount of black smoke is expeled by the exhaust . In the garage, they removed cylinder head, replaced valves and put new guides (even when those components were fine), new timing belt and put repair kits on both turbos. Now I continue with the same problem and someones new, because they didn´t rebuilt properly the machine. I heard vacuum system can be faulty. Someone could find out the culprit? Thank you!!!
Great video, with the issue explained easily. i just tested mine by squeezing the tube to close it from the side of my TCV and expected the popping sound to stop, although in my case it made no difference... what does this mean please?
The popping is vacuum related so because that check hasn't worked for you, have a look at the boost solenoid cleaning video in my list. That's assuming you have the Euro3 163.
Hi Rob I have the same popping noise on my Volvo S80 D5 2003 .. Volvo specialist told me the car is done .. car runs really well .. tried this .. still has the popping noise .. any advise .. all engine mounts are new .. car idles 700 as it should ..
hi my d5 makes this noise but when i blank the brake servo hose and the vacuum hose from governor, the popping noise stops completely. dose that mean my brake servo is faulty. no leak on vacuum pump. i blanked the engine mounts but noisy still happen. have you tried this?
Hi SiRobb, maybe you can help me ;) i have test it on a car i want to buy but the sound hasn't changed. On a test drive the brakes doesnt work like they should. I think the brake booster is the problem. Less power too at the acceleration. Could it be that the vacuum pump is defect and thats also the reason why it has less power? Also there is smoke coming out of the dipstick. Greatings Albert. I hope you can help me cause you know more about the volvos than the volvo mechanics.
Hi SiRobb, I don't really understand if you will see this or not but your video about the popping sound is very useful. I have a Volvbo V70 D5 Turbo. I have been losing intermittently the turbo. I have now discovered that I have the popping sound and it goes when the boost control valve is blocked as in your video, I am replacing the engine mounts and tubes and as the same vacuum operates the turbo I am really hoping the problem will be cured. Cheers. Any advice you have will be greatly appreciated. I'll let you know how it goes.
@@VIGtony Depends on engine. Euro 3 D5244T - vacuum loss affects turbo operation. Euro 4 D5244T4 onwards with single turbo - vacuum loss does not affect turbo operation Dual turbo may be affected. Basically, your exact engine determines likely problems and the relevant fix.
Hi mate I have the same popping noise coming from my D5. I have tried the same thing you have done but it's still popping. Do you know what the issue could be?
Nobody can explain why this makes noise in the drain plug ? I try to understand , but I do not understand the link between the media and the sound of oil cap
My D5 does this and it shakes alot when idling, but when driving you dont feel it. Is this the vaccum engine mounts that are ruined or is the engine becoming bad?
This noise/problem could activate safe mode when kick down? I have this noise and when I kick down at 3500rpm it brakes acceleration with violence and became safe mode.
Hi there great video very helpful my d5 got same noise but mines 07 reg 186 bhp model . How much does the engine mounts cost to replace is it a big job thanks
jchalmers28jc There's a video in my list showing replacement so take a look to see if it's a job you might try yourself otherwise ring around for quotes. On a 2 wheel drive, labour should be about an hour.
Hopefully helps someone. Symptoms: turbo hose had a small leak, black exhaust gases, after some time the hose was "open", smoke stopped, engine went into limp mode, after fixing the hose, the turbo did not work, DTC was P0244 I took a syringe and tried to create some vacuum to all hoses I could reach out to. - After that I only had the turbo working between 2.200-3.500 RPM *hope* - I focused on the intake manifold, EGR, or some other sensors. I was some minutes before taking out my whole EGR and cleaning it, kinda desperate hoping to solve it somehow not knowing what was the root cause. - Then I saw that video like 5 times, remembered that yesterday there was a hard popping knocking sound when I removed the oil cap while the engine was running. - Someone in another video said that it's quite normal and the sound comes from the vacuum pump, so it has to be there, otherwise the vac pump wasn't working. But: If you listen carefully what SiRobb says: the popping noise is the symptom of having a leakage AND it says that the vac pump is not the issue. Solution: I just took the hose which connects the electronic valve (location: mounted on the air filter housing) with the papenburg electronic valve (location: below intake manifold, near the starter motor, you have to remove the turbo intake pipes to get to it), and just stuffed that pipe with a small piece of wood I found on the floor. Assuming that my motor mounts have a leakage like he said. Crazy things happened after that: My turbo is doing things I never saw before 🙂 Thank You thousand times! Finally, the DTC is gone, meanwhile I had somehting with glow plugs bank something, also gone, currently I have a P0108 now saying "pressure too high", however I highly appreciate your work and will continue optimizing my vehicle, hopefully living a long life without incidents. specs: XC90 2005, D5244T, M66 AWD, 360.000km
@@7841239413264916324 Comment of the week. 😊 Glad to have helped and most importantly, well done with your persistence and attention to detail of actually listening carefully to my videos. Do that with all of the videos and for at least 100 videos, you'll be able to solve the most common D5 issues and more. What diagnostics are you running?
@@sirobb I’m using HHOBD OBD2 device with CarScanner on iOS and I also use an old thinkpad with has vida running on it. It’s the most important piece of tech regarding my car. After P0108 I had no error codes for a while. After some weeks P0088 appeared “fuel a system pressure too high” - well I think that it’s not THAT dramatic … hopefully Of course I will continue watching your videos, do researching cuz it makes a lot of fun to deep dive in all that stuff, learning, understanding and growing into it.
OK, brill video and thanks for being helpful, but i've just put my finger over the hole and i felt the vacuum there, but no matter how long i held my finger there for the noise didnt get any quieter. What does this mean?
If the noise is there at all engine temperatures, you need to further investigate the valve and vacuum system ideally with a vacuum tester. Lots of videos in my Playlist called Cars.
Hello Sirobb. Just bought a volvo v70 D5 2003, and I experiance the same problem as you, did the test. So how did you fix the problem, change the engine mounts? I have never seen vaccum tubes going in engine mounts. Best wishes Jussi
I changed everything ...vacuum pump w hoses and brake booster non return valve etc,...new PCV , new engine mounts ...both actuators...I still havethat sound
Hi sirobb ive Just bought a d5 Volvo S60 and it has this problem. Ive been looking through your videos you have posted and mine has most of the problems you have put up.
Your videos have help me a lot and saved me money and headache from the wife as she thought I bought a lemon.
Thanks again please please keep posting these realy helpful videos.
Same same for me Simon... mine doesn't have all the issues though...
But definitely you made a huge contribution to my pocket....
Thanks
Hi Simon, Hope you’re well, how are your swirl flaps?😮 I have problems with mine, wondered if there were any swell flap videos in the pipeline👍
I don't own a D5 but just wanted to thank you for taking the time to share this knowledge.
OMG man !!! I was REALLY WORRIED about my D5 engine, because of this sound. Now, at 1 am, searching about the issue, I have found your video - and yes , I can tell that this was my problem. Thank you very much!

Johnny Depp you mightve just solved my problem with the vaccum leak
Ive literallt replaced all the lines and mounts but still get the noise. Going to try this tomorow too see if it works
Hi Johnny, I have just found a similar knocking noise after pulling off the oil cap of my C30 D5. It sounds very similar to this video but higher pitched. Can you remember if the sound from your engine was higher pitched? Would I be able to contact you and send you a video? I still need to check the engine mounts the same way this video suggests and also push the break pedal hard like what you did and see if the noise stops. Cheers.
Did changing the brake booster solve the problem?
Did u fix it ?
This is What i call superb info from an Expert in my opinion, You have a lot of videos and i like them very much AS this is important and simple info, No volvo Dealer will tell you, at least not here in Norway (NoWay🤣)
Keep up the good work!

Полностью с Вами согласен😊
You are so right about so called experts I know this through bitter experience. Recently I took my 2007 D5 to a workshop fir a crank shaft seal replacement, a 7-8 hour job listed in Volvo schedules of work. The workshop took the whole engine and gearbox out, split the two, replaced the seal, replaced the whole unit resulting in a car that would not run properly below 2k revolutions. 24 hours work, a car unuseable and they wanted £1400, and I bought the seal.
I removed the brake booster vacuum hose from the vac pump and this popping noise STOPPED! Stick my finger over the pump inlet and the popping starts again. How contrary is that. Very good videos and much appreciated.
Use a vacuum tester and and check at different engine temperatures as the EGR position can cause the popping noise even with a sound vacuum system.
@@sirobb That does make sense, thank you. I was having slow start issues with my xc70 and tracked back to the ECU not seeming to transmit a signal to glow plug relay, also the original volvo glow plug connectors were really craply done so I have just made a whole new glow plug relay and distribution system controlled by a NO micro push switch mounted on plastic panel near gear stick. Also noticed that when the coolant temp switch is removed, the car is fooled into thinking it's very cold so opens up fuel rack etc and starts immediately (sort of puts it into beast mode). So I have run that to a NC momentary switch next to the glow plug relay witch. One way or the other, that get it started! These are so well built, but sometimes a bit too clever so we have to rethink the electrics. Before I got it the history shows a fortune spent at volvo garage to fix glow issues, fab remedies like wrapping tap around the glow connections!
Today I have tested this and had the same noice and same fix you show... But im comcern of your video I would recommend you to check your PCV that not excists and your camshaft Thank you for your Videos, Mate...
Hi sirobb ,kept most of your vids,very helpful,been in motor trade 55yrs,got this xc70 countryman diesel to sell 2 yrs ago with 229k on it one owner war and peace history ,now 235k as I couldn't part with it as it does every thing it comfort and ease,one thing I've had a go at to no success,engine check message,lack of power,checked most thing gave up taking turbo of to degrease the vanes as it looked a right job, I just drive and when it does it I flick of the ign and on again and carry on driving,worse when cold so I don't Rev it to much then,had egr off etc cleaned it all,inc top rocker box,some crap in there,thank gig for
Sorry not finished my quote,never mind,thanks still doing it...
I own an D5 with engine damage cause I've a good engine to replace. Thr engine runs and To hear was this Noise (thanks to you i knew what it is) and a metallic hard noise from a defect top engine mount. a detective Glowplug prevent from a good start. So the previous owner had been informed by the workshop that engine damage was imminent and he sell it cheap.
It's a shame what workshops tell his customers for a bullshit for the next order. Ok the dpf was full cause glowplug failure but I repaired it all and have a very good in shape v70 phase 3 for much less than good in state running cars....
Thanx again
Hi SiRobb
Just wanted to thank you for the well presented & informative videos. I have recently acquired a V70 D5 and as a retired heavy truck fleet engineer I guess I would eventual get around to learning some of the stuff you have presented in such good tutorials. Very impressive.
Thank you Dave
Well thank you too Dave for taking the time to comment.
It's always satisfying to hear folk find my ramblings useful and welcome to the Volvo fold. ☺️
It's 3 plus years since I previously thanked you for your really impressive tutorials Simon and you continue to do some great stuff.
Just wondering could you direct me to anything you have experienced on changing the Volvo HU-850 radio with another of same model coming from same year V70. There appears to be some sort of software mismatch, CAN bus issue and proving to be a nightmare. I don't have VIDA or DICE but would buy if a code change is possible. Dave
Just subscribed because you've done a great job with this diagnostic...Have been running Volvo XC90 D5 for the past 7 years (on my third car now) and these are the best tips. great man, thank you
You sure told the experts! Nice job, handy thing to know for D5 owners, many thanks.
Don't ya think there could be a small african with a drum down there? I wonder if same goes for the petrol engine?
I have an XC 70 that loses power every now and then. Lots of parts been replaced but still have the same problem. Anybody come across this problem before had full service and changed the cam belt but still the same intermittent problem any ideas please
Thanks for this, that was really helpful. I didn't realise my engine wasn't supposed to be as loud, and had really bad power loss on my motor coming home from holiday! Going to try this tomorrow and order new mounts
10 more years, and I'll learn to fix all parts of my 700K D5. Thanks!
Thank you... You are a Legend. 😉
Everyone on here calls themselves an expert 😂.
Even the "technicians"
At my local main dealer couldn't diagnose this noise for me.
I did as you do in this video and problem solved.
My engine mounts are fine but the vacuum hose had come disconnected...
Probably the last time an "expert" had his hands under the bonnet.
Once again SiRobb does the job! My D5 is doing this and I know it is the mounts and I have a vacuum tester. But I actually think that pipe is not connected to the control valve on my car. I must check when daylight arrives!
Thanks for this video, had a very rare limp home mode issue and suspected a vacuum leak straight away and tested for this noise and have it, so luckily an easy fix
how did you fix it?
i have same issue but when i cover the turbo control valve is still makes the popping noise. what else is there to check ?
Check Sir Robb's other video on vacuum leaks
I also have a vacum issue with my D5. The noise doesn't go away even if I block the connection on the vacum pump itself. May this be caused by a leaking brake booster? I already have changed the O-ring on brake boosters plastic connector.
THANK YOU so much for your video you are the man my Volvo s60 d5 is fixed
My old D5 had this when i bought it, drove 100.000km with it then old it off to a new owner. never had any issues
Thanks for this video. My V70 has this same issue . Why do the engine mounts require a vacuum?
Genius videos, will create some work but save a fortune! Many, many thanks.
Very usefull, thanx a lot. My problem was solved after your advice
how?
Another brilliant video, I decided to check to see if mine had the popping issue and it dose, all engine mounts are new. I’ll be watching your other videos to try and locate the source of the issue! Thanks very helpful stuff
Well that’s Amazing ! Who’d have thought that noise in the engine was an engine mount outside the engine !
Just bought a D5 and I'm really glad I've seen this, as mine makes the exact same noise.
I now know what to look for! Thank you! =)
Thanks for the video. Had the same issues with the sound coming from the filler hole. Also people said it was a crankcase ventilation problem but ventilation was all clear... Gonna check the vacuum hoses tomorrow. I already blocked the engine pads a long time ago so it could me the lines to the turbo.
Mate your a star. I just bought a v60 es 63plate and I've not had a Volvo before. Lovely ride o ly done 60 miles but theres a hissing noise like a turbo leak or inter cooler leak ect
Dose seem propper sluggish but I've been that busy mot had ti e to look. I just tonight opened the oil filler cap and heard this load popping noise and my neighbour who was 50 ft away said "oh that's fucked get rid of it... "
hello, if you plug the hose in and the sound goes away, it means there is a leak somewhere, if the sound is knocking, it means there is no leak or
So smoke is perfectly normal for a d5 pheww. I've be maintaining mine like a crazy man. I haven't got the excessive popping noise but a bit of smoke from the oil cap. I'm running miller's 5w40.
hi
my d5 makes this noise but when i bloke the brake servo hose and the vacuum hose from governor, the popping noise stops completely. dose that mean my brake servo is faulty. no leak on vacuum pump. i blanked the engine mounts but noisy still
I agree - Fantastic! mine does this! I nearly walked away. So glad I didn't. Best wishes Tony :-)
I have same problem on my s80 2011 D3 engine and i asked to volvos service this problem but they said that this is normal ... i gonna test it if d3 have same vacuum system like p2 volvo.
Thanks for great video !!!
volvo s60 d5 is in my opinion the best second hand diesel saloon car you can buy .
There's many who agree with your opinion, myself included.
Hey, SiRobb thanks for this excellent tip! Have been watching your Volvo videos for a while !! Absolutely great!!
quick ? Rob, why do engine mounts need to be supplied with a vacum? So interesting, and forgive me if it`s obvious but i am not very mechanically knoweldgeable to be quite frank.
Thanks for all your videos, i have just bought a d5, 2006 model, and seeing this wealth of info you have shared with us has helped me decide to purchase this car.(my 1st Volvo!!) Still gotta go fetch it, so have only done a test drive thus far, but what a car is all i can say for now. :)))
The vacuum softens and hardens the mount to improve engine damping and reduce cabin vibration.
thanks man, you are great to bother replying to me.
My son in Germany googled it the other day when I was chatting to him and.I'm happy to hear he is right!😊
Was wondering how long I can let it go on for, any danger to the turbo I hope by leaving it for a while?
These motors fuel economy is allegedly 6,5 l per 100km(i think-its the d5) but with a well serviced engine and driving responsibility(mellow acceleration etc, I am an experienced driver) I'm wondering what kind of fuel economy I should expect.
Any idea here Rob?
(It might be a good indicator of excessive vacuum leakage from those engine mounts..)
No worries if its asking too much, but if you have some idea, I'd appreciate some insight here.
Cheers Rob.
Top Man! Always wondered what’s the source of that noise when I opened oil filer cap on my D5’s XC60 and V60. Thank you for sharing
Hi SiRobb, I have a XC70 D5 2005, got the same noise when opening the oil filler cap, WIll try to remove the hoses to the engine pads, I also agree it is a vaccum issue, my question, I was probably stupid when I blew compressed air into the hoses after removing the hoses from the TCV. Do you think I have damaged something with the compressed air. The turbo is not working anymore but that could be linked to being clogged with oil sauce after the oil cooler broke. Thx and best regards from a Swede living in Germany having three Volvos. XC70 D5 , V70 GLT 1997, S80 V8 2007 with Heico sport exhaust.
Too bad your car seems not to have the parking heater installed. This component fails all the time on the up-to-2006 models. A repair and disassemble walk trough would be fantastic.
Your video's are great!\
Absolutely brilliant tutorial videos Si, Rob, SiRob. Imo the very best Volvo tutorials on RUclips 👍👍👍 I have just bought a XC90 with 105K miles with enjoy popping, now I know it's nothing really, the other thing is a rattly noise from down by pulleys on idle but when rev up it goes, I was thinking it could be air con pulley? Can I replace the pulley? Cheers.
Lovely, thanks so much!
And while the Volvo world might be small - you are one of the great..=*^)
I'll check out the other video right now.
Hope to run into you some time and be able to say Thanks face to face..=*^)
Thanks again!
Did think my self omg hes right. Is it out of oil I thought. Then couldn't find any dipstick!!° I'm an engineer an I've stressed out about this all night untill I've seen your vid. I think there is a few problems with the car but I'm now understanding what is going on without having to ask a main dealers help.. expensive and clueless
WOW WELL DONE FINDING THIS KNOCKING NOISE PROBLEM !!!
I have bought 2008 xc90 d5 for my dad 3years ago with this noise. I knew then that it was something to do with vacuum but could not find what. Ever since it bothered me but now I know what it is and can fix it. Thanks
Again, he's the man Sirob
Thank you.
Hi Robb, interesting video. I think in 38yrs of driving I’ve never undone my oil filler cap whilst the engine was running. Of course I now have on my recently purchased winter ride 04 V70 D5 😱 the popping sound is there on take off, car drives well otherwise. Hopefully it can wait until the Spring when my Summer car comes out again.
I have this issue as well as many others apparently. I found that unplugging the electrical connector on that valve closes it an the popping goes away. Since you call it Turbo control valve, does it do anything else than provide vaccum to the motor mounts? I am thinking that I will leave it unplugged until mounts are replaced, good idea? Thanks for this good information!
Tank you . You are a smart one ! If someone is tell his self (specialist) don’t meen that is smart too . Sorry for my language
Sorry for asking dumb questions, but what part do you have to change if you have this noice and did the same as you did?
So I have watched your video, and found I also have the “popping” issue. However, when I block the valve off like you did, the pop continues and doesn’t change tone in any way. Soo, what could it be 🤷♂️🤦♂️ D5 XC90
I have made the same test. Sound does not change. Any advices?
Just got a d5 & thought I'd test this myself but someone has disconnected both the hoses from the mounts. I have this noise but can't figure out where it's coming from if both mounts have been disconnected. No fault codes on the car when driving it does make a turbo noise I'm guessing that's normal though
Thx sir for this aweaom vodeo!I have on my s69 D5 low acc and issues over 2500rpm,and the error code is 6805.All happen ed when in one workshop cleaned my egr valve!
Hi ! Thks for your videos . I have D5 2008 on XC70 , i have popping noise like the video , could be the hodraulics engine mounts ? Or mi car dont have. Thks you very much.
hi Sirobb I am a french, the youtube translation is not good I can not understand. I have a d5 and it makes the same noise I would like to know what was the solution to the problem. Your videos are a great help to me! thank you very much!
Got the motor service light coming on, and a rough wobly engine so I thought change the engine mounts. Tried the test with the hose to the control valve and still the same noise. So I'm not sure what's going on there
Ok so I’ve got it the other way round. When I hold my finger on the vacuum pump I get the popping noise. But when I let go it is quieter. I’ve got a thudding when it’s idling and other people have said it’s the mounts but it’s the opposite to this video
OMG I HAVE THIS!😧 I have had loads of V70’s but never came across this before🤷🏼♂️ I am an engineer and annoyed i couldnt find what it was i have never heard of VACUUM ENGINE MOUNTS! I need to change my lower steering UJ before the MOT as its starting to feel ‘vague’ so its that. When its up on the ramps ill change the mounts. NEVER heard of any manufacturer doing this before, totally new to me 🤷🏼♂️ CHEERS SIROBB I was thinking big ends but the engine PURRS and is very pokey so not that?
Have this noise, changed the vacuum mounts, still persisting, leaving comment here for reference thank you it's very helpful
You could check the vacuum pump. It could be worn and therefore making noise. Or it's leaking vacuum
@@maximilianschmidt1443 where do I find this in the engine bay? Thanks for the tip I will look into it
@@LucasW.B when standing in front of the engine, the pump is on the right side of the engine. In the back, just next to the upper engine mount.
There is a vacuum pump testing video in my list.
@@sirobb I just found that after posting the comments x)
Thanks a lot for all the D5 info it's been a huge help in understanding how my car works and all the possible failure points, they can make many miles** but must be well maintained and you've helped ever so much! :)
Volvo for life!
Hi. Great videos! I've tried cleaning the tcv an blocking the pipes all the way down to the pump. Blocking the vac pump wont help. It seems as there is a lack of vacuum. Testet it with a vac gauge. The vacuum comes in pulses, and it wont build up, it just flickers. Removing the maf makes it even worse. Thinking its the vac pump thats broken. Just wondered if there are any other things I can check before I get a new one? Can't see how the maf sensor has anything to do with vacuum the pump produces? I have the EURO3
Christopher
See my video here ruclips.net/video/0zsIa4Y2Tcs/видео.html and put the vacuum tester directly onto the vacuum pump.
If the needle flickers and doesn't stay stable, the vacuum pump is faulty or the vacuum pump seals.
Buying a used pump should be quite cheap because they are very reliable so not in high demand.
Thanks a lot! Appreciate your help!
Christopher
Can you explain why the engine mounts me CREATE noise in the oil filler cap ?
Is the breather operates on the same vacuum system ?
Sorry for my english
Hi Sirobb! i had the same problem. the popping went away by isolating the rear mount- changed the mount and the popping is still there. The line itself holds preassure. Im stuck now. One volvo garage told me that they have seen many euro 3 engines that have this popping that goes away by isolating the rear mount even when the mount itself is fine. Is that true? is the rear mount supposed to leak some vacuume?
The rear mount could be perished and releasing vacuum and replace the vacuum hoses
@@abood_abtv4203 In the end i ended up swaping out both vacuum actuated mounts and vacuum hoses and the vibration in cabbin got even worse- transmissions tarted touching the subframe at times so another independent garage swapped out all 3 rubber mounts (for Lemforder) since they all were perished and only then found out that the new "Febi" vacuum mounts were both shot (assuming- defected from factory or just designed badly") and leaking oil when removed for inspection once again. Got "Lemforder" ones and all the vibration and popping went away.
I've got exactly the same noise on my D4 2.4 diesel. Very loud popping noise but I don't have a turbo on the car? Probably a vaccum leak by the sounds of it but I can't find it
Why does it have vacuum to the engine mounts?
Hi ,Robb my name is Vas, I have volvo xc90 d5 2005 ,I have problems with my volvo is running really rough, is popping like in the video I have checked the turbo control control valve
SiRobb,thanks for this and the other videos. I just find this noise in my s60. Temporary fixed for a screw.
Need quickly changing the mounts or enough few weeks later? Thanks
I don't find the turbo control Valve on my 2008 V70 D5. Do you know where is it? I have the same problem
thats told the know it alls, i think the easiest way to deal with volvo's is to keep on top of them by regular maintenance a servicing, they do need looking after..
Hello @sirobb Aside of the popping noise, the noticable engine clicking noise is perfeczly ok? Or it might be problem with hydraulic lifters? Thank you!
So on a 185, and the noise doesn’t stop when you block the pipe the noise doesn’t go. Unless you rev the car up, does this meant it can only be the pump? Cheers
8 years later this video just saved another volvo, any idea why my noise could have been intermittent? coming and going with the oil cap off.
@@cocktail3018 The noise can change with engine heat and the position of the EGR valve so not always obvious.
Sirobb do you actually know how the loss of vacuum is causing that popping sound. Obviously, it is a vacuum issue and my D5’s popping noise is even louder than yours so I am just trying to understand what exactly is popping in the engine. Many thanks!
Wow just started hearing this slightly every now and then I have the 2013 p3 205 hp twin turbo is it possible for this engine or are all d5 s basically the same just different turbos etc
Exact same symptom on my Euro 3 D5.
Is this something that would be harmful for the engine to drive with over longer period of time, or is it just a concern or not while idling?
Runs like a train, but I’ve started to feel signs of a bad engine mount when I accelerate and then let go of the throttle quickly (just to diagnose if it was the mounts or not)
Mine (XC70 D5, 2010) have the same problem, with 130k km on it. Too, after 1800 revs, a great amount of black smoke is expeled by the exhaust . In the garage, they removed cylinder head, replaced valves and put new guides (even when those components were fine), new timing belt and put repair kits on both turbos. Now I continue with the same problem and someones new, because they didn´t rebuilt properly the machine. I heard vacuum system can be faulty. Someone could find out the culprit? Thank you!!!
Great video, with the issue explained easily. i just tested mine by squeezing the tube to close it from the side of my TCV and expected the popping sound to stop, although in my case it made no difference... what does this mean please?
The popping is vacuum related so because that check hasn't worked for you, have a look at the boost solenoid cleaning video in my list. That's assuming you have the Euro3 163.
+SiRobb thank you. i do have the 163hp model. so will check out your other video. is it the Cleaning Volvo D5 Turbo / Boost Control Valve?
+Richard Roberts Yes that's the one. 👍
You can also peel up the metal rim and remove pipework and inspect the rubber diaphragm to check for splits.
Normally if smokes through oil cap or oil jauge there's a compression issue, with burned piston rings...
I gavē the same problem but the sound goes away when I stop the vacuum from going to the brake booster maybe you’ll have some advice
Hi Rob
I have the same popping noise on my Volvo S80 D5 2003 .. Volvo specialist told me the car is done .. car runs really well .. tried this .. still has the popping noise .. any advise .. all engine mounts are new .. car idles 700 as it should ..
hi
my d5 makes this noise but when i blank the brake servo hose and the vacuum hose from governor, the popping noise stops completely. dose that mean my brake servo is faulty. no leak on vacuum pump. i blanked the engine mounts but noisy still happen. have you tried this?
Hi,you are too strong 🛠️👍 thanks my Friend🙏✌️
Hi SiRobb, maybe you can help me ;)
i have test it on a car i want to buy but the sound hasn't changed. On a test drive the brakes doesnt work like they should. I think the brake booster is the problem. Less power too at the acceleration.
Could it be that the vacuum pump is defect and thats also the reason why it has less power?
Also there is smoke coming out of the dipstick.
Greatings Albert. I hope you can help me cause you know more about the volvos than the volvo mechanics.
Hi SiRobb, I don't really understand if you will see this or not but your video about the popping sound is very useful. I have a Volvbo V70 D5 Turbo. I have been losing intermittently the turbo. I have now discovered that I have the popping sound and it goes when the boost control valve is blocked as in your video, I am replacing the engine mounts and tubes and as the same vacuum operates the turbo I am really hoping the problem will be cured. Cheers. Any advice you have will be greatly appreciated. I'll let you know how it goes.
Thank you. Have a look through my videos. There's more available including changing the engine mounts. Good luck. 👍🏾
Do you think that the vacuum loss would be enough to make the turbo boost not work intermittently Cheers
@@VIGtony Depends on engine.
Euro 3 D5244T - vacuum loss affects turbo operation.
Euro 4 D5244T4 onwards with single turbo - vacuum loss does not affect turbo operation
Dual turbo may be affected.
Basically, your exact engine determines likely problems and the relevant fix.
ticking noise from my d3 ( 5 cylinder 2.0 liter diesel engine) volvo xc 60 2012. do you know what can it be?
Salut, i-ai dat de cap? Și eu am aceeași problema
Hi mate I have the same popping noise coming from my D5. I have tried the same thing you have done but it's still popping. Do you know what the issue could be?
Nobody can explain why this makes noise in the drain plug ?
I try to understand , but I do not understand the link between the media and the sound of oil cap
My D5 does this and it shakes alot when idling, but when driving you dont feel it. Is this the vaccum engine mounts that are ruined or is the engine becoming bad?
RITO PLZ You need to test the mounts.
See my list of videos.
This noise/problem could activate safe mode when kick down?
I have this noise and when I kick down at 3500rpm it brakes acceleration with violence and became safe mode.
Hi there great video very helpful my d5 got same noise but mines 07 reg 186 bhp model . How much does the engine mounts cost to replace is it a big job thanks
jchalmers28jc There's a video in my list showing replacement so take a look to see if it's a job you might try yourself otherwise ring around for quotes.
On a 2 wheel drive, labour should be about an hour.
Hopefully helps someone.
Symptoms: turbo hose had a small leak, black exhaust gases, after some time the hose was "open", smoke stopped, engine went into limp mode, after fixing the hose, the turbo did not work, DTC was P0244
I took a syringe and tried to create some vacuum to all hoses I could reach out to.
- After that I only had the turbo working between 2.200-3.500 RPM *hope*
- I focused on the intake manifold, EGR, or some other sensors. I was some minutes before taking out my whole EGR and cleaning it, kinda desperate hoping to solve it somehow not knowing what was the root cause.
- Then I saw that video like 5 times, remembered that yesterday there was a hard popping knocking sound when I removed the oil cap while the engine was running.
- Someone in another video said that it's quite normal and the sound comes from the vacuum pump, so it has to be there, otherwise the vac pump wasn't working.
But: If you listen carefully what SiRobb says: the popping noise is the symptom of having a leakage AND it says that the vac pump is not the issue.
Solution: I just took the hose which connects the electronic valve (location: mounted on the air filter housing) with the papenburg electronic valve (location: below intake manifold, near the starter motor, you have to remove the turbo intake pipes to get to it), and just stuffed that pipe with a small piece of wood I found on the floor. Assuming that my motor mounts have a leakage like he said.
Crazy things happened after that: My turbo is doing things I never saw before 🙂 Thank You thousand times!
Finally, the DTC is gone, meanwhile I had somehting with glow plugs bank something, also gone, currently I have a P0108 now saying "pressure too high", however I highly appreciate your work and will continue optimizing my vehicle, hopefully living a long life without incidents.

@@7841239413264916324 Comment of the week. 😊 Glad to have helped and most importantly, well done with your persistence and attention to detail of actually listening carefully to my videos. Do that with all of the videos and for at least 100 videos, you'll be able to solve the most common D5 issues and more. What diagnostics are you running?
@@sirobb I’m using HHOBD OBD2 device with CarScanner on iOS and I also use an old thinkpad with has vida running on it. It’s the most important piece of tech regarding my car.
After P0108 I had no error codes for a while. After some weeks P0088 appeared “fuel a system pressure too high” - well I think that it’s not THAT dramatic … hopefully
Of course I will continue watching your videos, do researching cuz it makes a lot of fun to deep dive in all that stuff, learning, understanding and growing into it.
OK, brill video and thanks for being helpful, but i've just put my finger over the hole and i felt the vacuum there, but no matter how long i held my finger there for the noise didnt get any quieter. What does this mean?
If the noise is there at all engine temperatures, you need to further investigate the valve and vacuum system ideally with a vacuum tester.
Lots of videos in my Playlist called Cars.
What if I plug it if for a mean time until we fix the problem. Would it do any harm to the engine?
i have exact same sound and smoke like yours but i have v70 2009 2.4d any ideas on what it can be? appreciate it
How much engine pressure is normal? Pcv
Can you do a glove test on the oil (cap)
Hello Sirobb. Just bought a volvo v70 D5 2003, and I experiance the same problem as you, did the test. So how did you fix the problem, change the engine mounts? I have never seen vaccum tubes going in engine mounts. Best wishes Jussi
I changed the mounts. There's no other fix.
@@sirobb oh Okey so I will get new mounts. Thanks for answering
Hi there can u tell me if am best to block the pipe of till I get mounts fixed .good vid 👍🏼
As a temporary solution, you can block the vacuum feed to a leaking mount if you have a Euro 3 163 D5 but if you have a Euro 4, there's no point.
I changed everything ...vacuum pump w hoses and brake booster non return valve etc,...new PCV , new engine mounts ...both actuators...I still havethat sound
went looking at an xc70 last week at a very reputable second hand dealer who told me this was normal , walked away luckily.
