I always say i want to film videos like this. But it ends up taking 3 days due to some stuck bolt and then i just want to get the job finished. Thank you for taking the time to film this. It is really helpful
Thank you Joseph! 😃 Yeah it really makes life harder (at least 2x harder) trying to do a video at the same time. But it's worth it if it helps fellow enthusiasts out.
You're an absolute gangster for this, THANK YOU. I wanted to clean out my intake, and I got to the point of having all the intake bolts out and couldn't get her out. You helped a ton. I hope I never have to do it, but at least I know how now!
Haha cheers, really glad it helped! They aren't that fun to work on these engines, unfortunately. I used oven cleaner to clean the intake out, it worked pretty well, see my next video on this topic if you're interested in seeing that.
G'day from Melbourne,Oz..just found your video after trawling youtube for info on my coolant leak..I have a 2015 VW Touareg with 175k kilometres (approx 108k miles) when my red coolant warning light came on..have lost coolant from the reservoir,and can see a small pool in the plastic dirt cover under the front of the engine,so not exactly sure where the leak is at this point. Will have to investigate further,but from what your video has shown,i feel confident to try and tackle this job. Many thanks for uploading this,mate. Gave it a like and subbed you 👍
Cheers David! It could quite well be the same issue, when the valley of the engine fills it can run down the front under braking for example. Hope you figure the issue out, I was topping mine up for a while but I think it's fixed now. 3rd video on this issue to come soon. 😃
@@davidrichmond471 Mate if you lift the plastic cover off the top of the engine and shine a torch right in the V section of your motor youll see the coolant.
Haha cheers! It felt like a heck of a job taking the thing apart. Whoever designed it was not planning to ever work on it... I've not had to actually take my shoes off and get into an engine bay before. 🤣 Doesn't help that the Cayenne is massive either.
Hello from the USA and thanks for posting this video! I've done three of these - two Q7's and one Q5, and it was somehow enjoyable to watch someone else struggle with getting that manifold out! I'll mention that the coolant bypass valve is known to leak at it's shaft. Even though it's expensive, it's worth it to replace "while you're in there". FCP Euro is also a great source for the parts to do this job. Audi dealers want $5k USD to do this. Cheers!
Haha you're a seasoned vet on these diesels then! Reassuring to know even you have a fight removing the manifold. You'll be glad to know I have a coolant bypass valve on the way, I wish I had changed that first time around but I wasn't aware of the way it could leak. I'm not that surprised dealers want 5k to fix a leak on these! 😆
@@SPANNERRASH looks like I’m the the right direction in replacing the bypass valve and thanks to @covenantmotorsinc for confirming this. In Australia they want 3k for this job 🤮
@@tiptopautodetailing68 I think I'll be changing this part out at the same time as you. I picked one of these up: ebay.us/vKCbCF You can get very cheap aftermarket ones at £30ish, but based on everything I have read, I opted to go with genuine like the one I linked. Apparently they updated the design to make them more leak resistant.
I'm 30mins in and I just want to say THANK YOU for doing this blind and explaining things so well. I greatly appreciate it! I will be draining my oil before starting this job and have a shop vac handy!
Really glad the video is proving useful for you! Wise to drain the oil first, and coolant. When you remove that oil cooler base plate both fluids will want to mix in the valley of the engine and its a right old mess. As you see in the vid. 😆 Hope it works out!
What a great channel. I've just subscribed after watching your struggle with starting up the E30. I have replaced the engine on my E38 (M52B28TU) and I'll be starting it soon, hopefully with smoother results 😅 And then I look at your newest video and you're fixing coolant leak on VAG 3.0tdi, which I had in my daily driver A5 a year ago. I fixed mine with Liqui Moly stop leak 😂
Awesome, welcome aboard mate. Hope the E38 project is going well, what happened to the original M52 it had? Did the Liqui Moly stuff really work to fix it? 😆 I thought that was all snake oil and was more likely to clog your cooling system.
@@SPANNERRASH I had a mint engine in my E38 and one day, oil pickup tube broke and fell down the pan. I guess previous owner must have knocked it when putting pan in place, it cracked and eventually it failed after.. 4 years of me driving it 🫣 Regarding the stop leak, I was very surprised myself but it did the trick. No issues whatsoever since I put it in, perfect temp all the time, no leaks 🤷♂️ Btw, I love the choice of music for your videos. Perfect match! 👍
@@Solder-Flowz Dang, that's such a shame about the M52, I bet you were gutted about that. Very interesting, I will bear that in mind about the stop-leak. I'm still sceptical but it could be a good backup in a pinch.
The egr valve flange leaks at the section of hing, this is the most common problem audi has made a new part and different part number as its seated to stop this issue , I done the same as you and put all back together and found it dripping at the rear , changed the part with no issues now
I don't have the car but still found the video really interesting. If it had been me doing it one of the bolts would have snapped off in the block😊. Well done (hopefully)! Looking forward to seeing if that fixed it.
Thanks Phil, I hope it was entertaining for you. This Cayenne is not as fun to work on as an old BMW or a bike. Thankfully no snapped bolts this time though.
@@SPANNERRASH Thank you! In regards to seals I will be replacing the exact same lot as you + a new coolant bypass valve. After watching your second video did you end up finding out what is still causing the coolant leak? Thanks again
@@shuaikezz Pretty certain its going to be that coolant bypass valve, it looked good but apparently a very common leaker. I should have changed it but didn't realise at the time! I'm yet to go back in and sort that, hoping to do it this month but using the car daily.
@@SPANNERRASH thanks, all the best with doing the job again, at least you won’t need to spend time cleaning like before so should be quicker and smoother
Mate 10/10 for your filming angles. You and your assistant take the time to reposition the camera so as to show exactly what's going on. I'm a BMW man myself. Have a E70 and the missus has an E60. The VAG V6 seems a tad more complicated to work on you think? Toying with the idea of buying a Cayenne as Ive been told they not too bad on reliability. Like you I do most if not all repairs myself and I do them right. How would you compare that with working on a BMW straight 6?
We do try hard to make these vids helpful and detailed for people so thank you! 😃 The way this VAG V6 TDI is packaged seems way less mechanic-friendly than I'm used to with older petrol BMWs. It seems to be laid out in a more chaotic way, everything is packed tight and tangled together. You feel like you're going to break things getting them in and out, but there's no other way it can go together. I'm used to working on older BMW E30, E36 and E46 where there's actually room to get your hands in to work without needing to strip everything down. 😆 If your E70 and E60 are 6-pot diesels you might be more familiar with this extra complexity and not as challenged as I was. I'm starting to gain a bit more confidence in working on it now, and things are pretty well documented about these 3.0 making jobs more doable DIY style. Hopefully that continues!
Great job buddy, that was well worth investigating the other potential issue areas whilst you were in there. Thorough wrenching that. Is the engine vibration what's causing the flange to snap? Is there an upgrade available? What a car though! Looking forward to more content on it.
Thanks pal, glad you enjoyed the vid. This VAG 3L TDI is far too intricately put together for its own good, no wonder they get valley leaks with the number of plastic parts and rubber seals... It might well be the vibrations causing the intermediate flange to snap actually. Mine definitely looks like it's been broken and leaking for a while. Really hoping that's the whole problem, it seems likely right now. I've seen billet replacements for them, but they seem to be only compatible with EGR deletes, and I've decided not to go down that route as I don't think it's allowed. 😅 I am planning to replace with another plastic one and hope it goes for another 130k miles!
@@SPANNERRASH There's a good chance there's been an amendment to the design, maybe a wider neck? Yes, EGR deletes are not allowed, which is a shame as the whole EGR system has added a whole bunch of issues to diesel engines. You can get them mapped out, and then you can blank them off. Good luck, hope the new part sorts it. It seems very likely it's the only source of the leak. Love the channel dude, absolutely no pretentiousness. 👍🏻
I recently has a German specialist mechanic centre do that Job for me. I'm in Australia (Gold Coast). They Quoted me only 8 hours labour so I jumped at it. They changed the reg valve in there and every seal they said may fail. Still their hourly rate was a little high at about 100 pounds an hour ($200AUD). I am happy. Job also include oil and coolant change. They quoted Parts at Porsche prices.
Sounds like you got a pretty solid deal there to be fair. On the FB groups people talk about getting quoted 5k or even more to do this type of job. Maybe because they aren't sure what they will find within.
@@SPANNERRASH Total cost was AUD$2600.00 including parts and oil change using Mobile 1 oil . That’s what they said they used. The place was called German Dynamics.
Hi mate , when’s the refit video ? I’m waiting on parts for the exact same failure , also did you have the prong part number for the broken flange ? Mine didn’t come with it
My Q7 mixing oil with coolant.. im assuming this video applies to me! 😅… great video, very detailed..by far the best I’ve come across unlike the speedy ones.. Got a thumbs up and subscribe from me.. Thank you 👍
Yeah I think a modern diesel is an intimidating thing to work on! Probably looks far worse than it is in reality, but it sure makes you reluctant to start a job through fear of not being able to turn back.. Give me a petrol 6-pot to work on any day.
What happened to your engine hoist point that’s supposed to be near the EGR pipe? Looks like it’s missing in the video. I’m completely stuck trying to get my intake manifold around it, but the hoist point can’t be removed with the EGR cooler in place. Chicken and egg situation.
To be more specific, you can see the two bolt holes to the right of the EGR cooler outlet around the 12:56 mark where the hoist point is supposed to be attached.
That's really interesting, I just reviewed the footage and I can see where you mean. There was no hoist hook point there for me. Maybe its not supposed to be left in place, but added when you need to pull the engine. Saying that, I have the one firmly in place beside the oil filter housing held on by two triple-square bolts, I imagine just the same as would screw into those two vacant bolt holes. Do let me know if you figure that out, is your car also a Cayenne? Mine is a 2013.
@SPANNERRASH I've got a 2014 A7, same engine. Weirdly, I was doing a bit more research on the intake manifold removal and found photos of a Q7 that showed the same hoist hook missing, so maybe it's only there on the sedans. Not really sure though.
I noticed that when stripping my Audi down, i was thinking i don't remember this part in the video. I just removed the upper bolt and pulled rhe bracket forward and out of the way.
The amount of plastics being used these days is wild. I am sure it made production cheaper, faster, and easier, but it does not favor longevity and reliability.
True that, lord knows what they were thinking... I guess they were never planning to warranty them this far down the road. It's a shame because its a really nice diesel engine, it feels turbine smooth to drive. Just no fun to work on.
Hi mate , when’s the refit video ? I’m waiting on parts for the exact same failure , also did you have the prong part number for the broken flange ? Mine didn’t come with it.
Hi mate, should be live in a week or two, having some delays. Regarding that intermediate flange, I believe part number should be 059121506H I've linked all the parts in the description, hope that helps!
