- Hi there, I hope this helps with potentially diagnosing your engine fault.
Although we would love to respond to every comment and message we receive, we simply cannot diagnose your car via the internet as we just don't have the time. I'd highly advise finding a local BMW specialist or trusted garage and relay the information to them, including this video if you would like.
Thanks,
Spencer
Hi, Never got a chance to say Thank You for this video.
I bought an E46 318 N46 Touring for Spares or repair with a growling vanos a few years ago, I didn’t have a clue what the noise was, but thanks to you, I replaced the offending exhaust vanos, (£45 for a used vanos from eBay) and the car ran for years with no further problems, one of the best E46’s I have ever owned!
Thanks mate!
Your more than welcome happy it helped you makes it worth making when someone is grateful thanks
What did you change? The outside part or you have to open the head of the engine and change the round part inside? thanks
I've been searching for a video related to this noise for months now, until i found this video. You my friend are the man and if i had the chance i would buy you a well deserved beer. Thank you so much.
Thank you very much!! I had the exact same noise when activating the VANOS exhaust unit with my Autel DS808 scantool. I removed my unit (inside-the-engine sproket, not the solenoids, those were fine) and opened it up. The inside walls had become completely uneven, being worn by the inside plates/flaps that turn inside the unit due to oil pressure. I changed the VANOS unit with one from STARK for about 200€ and the sound is gone!! Perfect idle and running now.
thank you so much!
been looking all over the internet but no one has given me a fix on this issue but you
Well thank you from Canada Spencer Latham! I've been trying to find out what this was because to me (or on my E46 M3) it doesn't sound like a "Rattle" as everyone always talks about. It sounds like a Diesel engine or like a knocking sound. This is the first video that I could clearly say it sounds like my problem (Obviously exhaust side vanos). I didn't expect to be facing this yet as I'm only at 73,000 KM. The craziest part for me though now is that these two parts for the exhaust (Pump disk and the pump drive unit with the tabs that break) are aprox $1300.00 Canadian. Not including gaskets or tools. It's nuts! Thanks again for the clear diagnosis!
thank you for the good comment
Man!?? I can't believe you solve the problem with an easy tip?! Thanks a lot and congratulations !!
This is one of the most helpful videos I’ve ever seen. God bless you sir...
Hi there please it helped you that's whtci make them
Hi bro can I have your whatsapp number I have a problem with the same engine I really need your help. Thanks in advance
I hear this sound in my car, I'm gonna pull them out and clean them and see if that solves it. Thanks so much. I have looked for this all over the internet and couldn't find anything. Keep up the great work.
Did it work?
So ??? The result
Would be great to see more vids on the n46 engine.
Very few of them out there for some reason.
My vehicle was misfiring like crazy , bought new coil Packs. Sparks etc.
Did what you recommended disconnected the top one misfire disappeared. Engine purred like a kitten. Haven’t driven it yet but sounds mint.
Don’t no how safe it is to drive with it disconnected but you definitely helped me out. Thanks man
Great video man
Driving without solonoids is ok, its klpike having the vtec disables on a honda the valves just wont open as far or for as long
Best video ever, i didn't have any problem yet, but this RUclipsr explained very well
tnx for video.. I have same problem, when I start in the morrning I hear the short noise and immidiatly ( 3 seconds ) noise gone. And Hesitation when accelerating from a stop,.. Power loss, especially at low RPMs.
AWESOME, video, Spencer, Thanks for taking the time out, and if i'm in norfolk in the near future, i'll bring a nice Pizza for you, or a McDonald's 🙂
wow you were dead on. i couldnt find anyone talking about this. everyone saying lifters and valves. GREAT video. thanks
Did you Solve it? What whas the problem? I have the same
It is worth pointing out that these engines employ two VANOS check valves, similar to N52 engine, but unfortunately on an N46 the cylinder head has to come off to replace them. I am writing this because these could fail and make a startup rattle too (they are non-return valves to keep everything primed with oil), even though the VANOS unit might be perfectly fine
awesome video. I have an E60 N52 engine and this has shed more light on the rattle situation for me.
I cleaned both vanos sensors out because they where blocked up. put them back in and the car started OK then started running lumpy after I took off the intake housing to find out where this rattleing noise was coming from. disconnected the bottom vanos and made my engine run OK instead of being lumpy.

hi Mark T no it cannot it's a totally different setup on the s54 and I would probably say 99 percent that the exhaust side of your vanos is warn that's the side where the oil pump is located and there is a hub bolted to the end of the cam cam shaft which has 2 lugs. those 2 lugs go into the round oil pump drive disc and the 2 holes that those 2 lugs slide into are supposed to be round but over the years they end up oval shaped and that is what makes the same sound as this n42 in the video I made. I can fix this for you but it is a total strip down and redy rebuild of the vanos new seals and a new rocker cover gasket set also. if you would like a quote for the job contact me through my work page bmp conversions. I'm located in Norfolk UK hope this helps
My 2008 MINI Cooper S has such a similar sound. It's intermittent, but definitely not related to cold starts. It will have that "Whirring, plasticky rattle" for an entire day and a half and then go away completely for 2 weeks. Anyway, thanks for posting because it will give me an avenue to pursue on my car since it sounds so similar. (I'm pretty sure my MINI doesn't have the timing chain tensioner problem)
Got a 2013 335i X-drive, with the exact disturbing clanking. Along with that noise, the engine misfires. Upon inspection, the #4 spark plug appeared to be the culprit, covered in black soot (but no gas smell). A compression test on #4 cylinder showed a lower compression than the others. (Possible stuck piston ring due to carbon build-up, and I intend on treating the cylinder to break it up.) I initially believed that the clanking noise was a bent valve, but there was no incident that I know of where it would bend without the timing chain breaking. However, unlike what was showed on this video, the clanking noise on my engine does not go away even when the engine has warmed up. I definitely will unplug the exhaust vanos to see if the noise goes away.
I've got the same n46 engine produces 148bhp & 200nm torque. I got a full service including a oil change recalled the car then slapped a k&n air filter. Drives smoother than ever
148bhp & 200nm torque from the factory
Have you replaced the timing chain tensioner? The factory fitted one is defective (too weak). Easy job and made a very noticeable difference to engine smoothness.

@@yardi95 ah ok mine was just making this noise earlier. But had a look underneath and it's like a oily he'll down there 🙃 hoping was just tempory I'm not sure. Doing the pcv anyway as blue smoke is prevailing. And if that fails I'm just gonna Chuck some stop leak in and flog it haha.
Yep, same noise for about 2 seconds on cold starts. But my e46 has the N42B20... Thanks!
i change the vanoss seal in bmw e 46 318i se 2005 now the engine rattal and vibrate making same noise like in your video, I also change the breather vent as well. I have loss power at time seems to want stall in junction so I have to keep raving
Spencer, You are a legend.
I have the same problem after going hot is running like this and heave smoke grey is making this noise in warm when it is cold is working Very good
Excellent knowledge mate!
Thank you so much for this video, helped a heap.
any e46 problems you no the answer too, please please make a video of it because we all do appreciate it!!! thanks
Thanks bro. Could you pls explain why it is make the noise when vanos activated. And how to fully fix it?
Hello what a good video it solved issue on my 320i
Great video am having same issues when i unplug the vanos solenoid the car run smooth.. But sometimes i got the oil light on can you help on that
Top work here well done 👍
I have the exact same problem exhoust vanos , Thank you so much God bless you , What should i do can i drive more like this ?
Thank you - extremely helpful. Do to know if this affects the N47T in the F30/31 ?
Hi Spencer, on start up on my 1 series (when cold) and sometimes hot.
i am hearing the exact same noise as above, but my engine also *hunts* i've changed the sparks and coils and now it's nowhere near as bad as it was, it still slightly feels like it *hunts* however at work i had it looked at and was told this was due to a timing chain, i have had the rocker cover off and it for sure looks really gunked up inside which suggested poor maintenance before i owned it so i spent some time cleaning it up, noticed the breather hose to the manifold / rocker cover was bodged, so i replaced it and spent more time cleaning up the cover side.
so far that has resolved issues with erratic idling and severe misfiring however the engine noise and *hunting* still remain it sounds like the chain is rattling like mad on start up but however under load the noise disappears i checked the chain and felt no play behind it, does this sound like a vanos or could this be a timing issue. Engine code - N45B16A 1.6/2.0 block - 116i
I have the same issues.
Do you solve the problem.
@@gogi4a22 clean the vanos
clean the vanos
Mine has had both.vanos from febi whole timing chain kit bga, genuine bmw oil pump and new chain kit still rattles got any idea?
Just as you show I had the same noise from my N42. I have replaced the timing gear as the top plastic guide had fractured and the exhaust vanos was shot. However I still have a misfire that comes as the motor warms up and a new coil pack made no difference.
Probably vanos plug accidentaly plug in wrong vanos solenoid. Try switch between the 2
I have similar problems on N46 engines with these codes 2A70 , 2D07 , 2CF8 and 2A83.. It also leaks oil from valve cover gasket for the second time and we changed it 8 months ago. Do you have any idea what could be wrong? Thank you.
thank you
you are awesome
Hi I got same problem on my n42 is it the solenoids I need to change so in this case the exhaust soloneid? I’m getting lots of different answeres cheers
Hi! Did you get that replaced? How much are we expecting for that kind of repair? I appreciate your help!
hello , nice video very helpful ,(Q) can you run the car at any speed without having any problem after this process.?
Hi mine has kinda same noise iv an n45 116i e87 mine has noise on cold start but not straite away just after maybe 30seconds on cold start the rattle happens stays on for like a minute and goes completly away could this be the vanos solenoid also runs tiny bit rough on cold start but runs fine after a minute of running has still all the power when driving
hi nick they have twin vanos 100 percent
I will post more as I work on them thanks
Gained a sub THANKS so much Sir.. Need that snap on tool in my life haha... Have a great one.. =)
Thanks for this great video. I have and odd issue if you can help. Mine has shown a lack of power in lower revs also when warm I have a loud whistle like sound that sounds like a bearing... it's not as I disconnected the serpentine belt. Could this also be the vanos?
Hi there the vac pumps on these engines and the n45 wear out and can mack a rattling noise from the rear of the engine so if the noise is from the back of the engine do a closer inspection thanks
Hi there, I have an e46 with an n46 engine and have the same sound on a cold start for a second or 2, but for the last 2 weeks my car has got harder to start from cold, once started it will fire back up straight away until left for a while, also noticed lower fuel economy, it idles at 700rpm and fluctuates by about +/-20rpm, could the vanos be also causing those issues? The car had a full service less than 1000k miles ago and has just had a new fuel pump fitted 4 weeks ago. Hope you can help. Cheers
Once upon a time German cars were the best.

I would have to ask questions at the Inlet side disable must also get noise
Hey nice video, i have a big question and hope you can help me cause no one could until now. I have the same engine as in this video and my problem is that the car have starting problems when the engine is warmed up it even shuts down after a second starting the car starts bad but keeps running i don´t have any strange noises and no power loss when the engine is running but when the car is cold it starts like it should.... any suggestions?
Hi there I have a exactly same noise on startup for 2 second it's a n47d engine
Hi i had issue with eml light throwing vanos codes and engine running ok so bought 2 new solenoids and fitted them started car and rattled like a dirty diesel at the north pole. Tried to do adaptions but its still the same. Any idea how a new set is causing it to rattle but old solenoids didnt make it rattle.
Thank you so much
Very helpful Spencer! Love the accent also.
Joy Sharp Maxwell hi there thanks mate I do try not to sound to Norfolk lol haha
I have similar defect in my bmw e87 116i What should I repair exactly? On some videos they are talking about vanos replacement kit as a reason of rattle noise, but I can't find such for e87. I want to avoid replacement of everything. Could you help me? Thank you in advance
I have 120i bmw with the same noise and i have snap-on diagnostic machine but i don't know where to go and turn this noise off💔
Hi. I have a question. I have a knocking come from my engine. But I don't think it's either of my Vanos unis or the solenoids. If poss could it be a stuck a tappet ? Only when you drive away the noise stops all together.. when started from cold or hot. It knocks. As soon as you drive away.. No noise.. It's a BMW 53 X5 with M54 3.0 engine.. Many thanks.. Lisa.
Mine is a slight one second rattle on start up that appears one in every 5 start ups. Can this damage the engine if this is ignore or does the rattle get worse. Thanks ever so much for posting this helpful video
Good video i have the rattle noise on my N45 not on cold start but on the road especially when revving on low speeds.. Please advice

I have this sound only when I crank up the car. Happens from time to time.

Hi and thank you for the video. Mine is a N43 E92 320i, My does same noise like yours but as it is in idle.I took the Vanos out and they were clean. I heard it's the injectors and HPFP.. would you look at my channel and hear it? I have the engine cover out. Many thanks in advance

Hopefully YOU will reply but im having a juddering issue with my n46 bmw e90 318i dunno if its the timing chain on the way out or the valvetronic motor needs changing or its the vanos solenoids shall i just unplug the exhaust one and see if the noise goes i take it thats what your saying to do if i have a simular noise to this bmw whod have one great to drive... when they drive
Hi mate I'm looking at a 2006 x3 BMW 3.0 diesel and when I took the oil cap of it made a loud taping noise from inside the taper cover when I put the oil cap back on it stops ?
Can this be the same problem with my the N52 engine that’s making that same ticking noise
can the same test be done on the m3 S54 ? ,mine just strated and when i rev to 2500 RPM plus it goes away! so i thinking the spline is at fault once oil pressure fill it quiets up! no codes ! thank you

hello I have bwm e90 318i with n46 engine and it makes the same lifter ticking sound as the n52 engines. I searched and found that the problem is only in with n52 and some other engines but not with n46?? yesterday bwm engineer said that my lifter should be ok but he didn't know what is making that noise. He also mentioned that oil has not enough pressure to reach the top of the engine. I don't know.. can it be the oil pump that causes this?? (ps. sorry for my bad english I'm from Finland)
The oil pump is the cuddling mother for all the sounds in the engine. It is safe for them. When its pressure is healthy, it will reach all the moving points with each other in a soft and beautiful sound. Wash the parts of the engine and work hard and you will find a really satisfying result and you deserve it, hero.
Hi Spencer, Do you know how I can deal with a P1170 and P1168? I have a BMW 320i E90 2006. The car misfires at cold start and smooth when restarted warm after driving for a liitle while.
What if vano probelm...it makes engine stop?
I have had the same noise, but just when driving off. When motor is hot it goes into emergency mode and i have no power. Error Codes show Valvetronic Motor, what do i have to do and how do you unplug it in n46 320i e90?
Did you ever figure this out?

Hi, I have this N46 engine in a 316ti. I occasionally hear a noise on cold start but I think it is more like the engine running dry (goes after less than a second when the oil circulates). I wonder if this also explains some of the complaints. I have it serviced regularly btw so it's not running old or incorrect oil etc.
