Inspecting & Cleaning VANOS - N42/N46 VALVETRONIC Retainer Spring Replacement [PART #3]
HTML-код
- Опубликовано: 23 июл 2024
- In this video series I diagnose and replace a broken retainer torsion spring that holds the intermediate lever pressed against the VALVETRONIC eccentric shaft on a N42 engine. I also disassemble and clean the VANOS unit and confirm the fix with INPA rough running menu.
PART #3:
0:00 Disassembling cleaning VALVETRONIC.
0:47 Installing new torsion springs without special tools.
6:22 Reinstalling VALVETRONIC bracket assembly.
11:27 Disassembling the VANOS unit.
18:48 Inspecting the VANOS unit for wear and damage.
24:01 How VANOS unit works?
26:44 Reassembling the VANOS unit.
28:59 Timing the engine.
36:18 Installing valve cover, wiring harness and ignition coils.
39:06 VALVETRONIC initialization and starting the engine.
41:35 Resetting adaptations, checking rough running cylinders and correct VANOS position with INPA.
45:53 Test drive and conclusion.
After chain replacement ( • N42/N46 Chain Replacem... ) I noticed that there are some ticking noises during throttle body to VALVETRONIC operation transition. During this transition the engine stalls but then recovers to "normal" idle RPM.
This car is 2001 E46 316ti Compact BMW with 200.000km on the odometer.

I have an N46 engine and man are they problematic but ever since I came across this channel, I took it upon myself to be my own mechanic and it's going fairly OK with the help of this channel, thank you so much for the time taken to make the recordings, explanations. Truly appreciate your art mate.
Thank you very much for the good quality and very thorough video. Excellent!
Thank you BimmeZer!! Already jacked up the car to do the inspection of the Vanos unit and also disassembly all the coolant system since there is oil on it, never ending story with this beauty (hope it will be the oil cooler radiator).
Very good made.Thanks for your great job!
Greeting from Australia. These video are absolutely brilliant. I just bought an E90 with some rattles in the rocker area. I now have the confidence to tackle any issues I find and have ordered all the required tools. Thanks very much...
Have you a video?
love your videos bro, used the chain and valve video already, not leaking oil anymore☺ when i have time im gonna check this procedure also. best videos on n42 and n46 here on RUclips!! keep up the good work
This is truly ZEN...! Thank you so much for putting in a lot of effort to make these videos. I've watched almost all your videos, since i have a 2002 318i. I'm quite convinced i'd be totally lost without your amazing, detailed and pricelessly helpful videos.❤
Thanks!
I wish we were neighbors thank you for this very informative video 👍👍👍🙂🙂
Enhorabuena,videos de muy buena calidad y realizacion.
Great job bro!!!!!
you are a good master my friend greetings from Turkey BMW service👍
Отличный ремонт!!
Super video.
Thank you so much.
Eventually, this guy is gonna 3D-print the new n42 engine for his bmw.
Спасибо 🙏 тебе добрый человек, очень полезная информация 💪👍
Thank you.
I encountering the same issue with cylinders 3 & 4 (roughness values 1.3 and 2 respectively). I did almost the same repairs as you did. I've measured the compression in cylinders and got 16.5 Bar in all cylinders except cylinder 2 (15.5bar). Now I thinking to check fuel injectors and knocking sensor, because knocking voltage in inpa for cylinders 3&4 indicating higher values (around 5-6v vs 3v for cylinders 1&2)
My vanos sprockets screws won't even budge to open. They are there pretty tight
thanks bro
Great. Could u provide link to video for Cyl #4 rough issue solving?
Bonjour depuis la France , un grand merci pour ton travail vraiment très professionnel , dommage qu on ne peut plus traduire en français , j aurais tellement aimé pouvoir plus te comprendre , cdt merci ! Ta vidéo aurait attiré plus de monde mais sans pouvoir traduire dans d autres langues , you tube te pénalise !
good job ! :)
intresting, to me the vanos unit seemed quite brillliant and simple. Not alot of moving parts :D great video m8 have a good one !
oh btw where have you gotten you're inpa from? i recently bought a new cable just so i could get inpa but for some strange reason there was every model execpt e46 and iallso checked other models incase some whould have the n42 in them but no :/
@@magnus3885 i think i got it on the CD with the cable. It an old version dough
I had to btidge 2 pins together to get the cable to work. I think some cables have a switch integrated so it works with newer and older models
Its simple in principle but when you get into details itxs quite complex enginering. But to be realistic... it's hard to implement this function in any other way...
@@BimmerZen yea thats true but to mee it would seem like these should be pretty reliable maybe the spring could fail over long time but if you do regular oil changes then it seems like these should never fail would be intresting to see a failed one how it failed. also the impa i know i now have 2 cables cuz i lost the first cd but demmit still does not get the software to work :( xD
I have codes 2A67 DME and 2B62. I replaced rod bearings and timing guide rail replacement. I did use the timing kit for the VANOS and cleaned out the VANOS solenoids. The car is way down on power. Any pointers please Bimmer Zen?
2A67 Valvetronic Internal Fault
2B62 Camshaft Sensor 1 Inlet
Did you check all the connections? Can you scan with INPA to get more details on the errors...?
Mine was also rattling on startup. I have since unplugged the valvetronic after the car started idling terribly when hot. Going to look into it during my summer vacation, curious what I will find to be broken.
:( I hope it's nothing to serious
@@BimmerZen I it is serious, I will just keep the valvetronic unplugged and not worry about it. ;)
Hola soy omar gajardo de chile, consulta, tiene algo que ver con que los vanos vengan con numeración por ejemplo escape 2b O Admision 1A?
In the 21:12 minute, when will these two pieces be replaced in full? And how do I know that it only needs cleaning and returning again?
Hello is this the seme for N45B16 engine?
Hi! First of all thank you for the detailed videos! You helped me understand the whole VVT/Vanos system of BMW. I have a question maybe you've faced this issue. I have a 318i E91 (2006) and I'm facing 2A6F - Valvetronic, minimum lift exceeded error code, I also have hesitation when idling and bad fuel economy. What would be the cause? VANOS problems or VVT actuation motor? I have also tried to reset the minimum lift (0.3mm) via ISTA+
Did you try to increase minimum lift to 0.4mm? Did you try scanning with INPA to get more info on the error?
@@BimmerZen It's either 0.3mm or 0.8mm, nothing in between. I saw a video that resetting it to 0.3mm resolves the 2A6F error. I run the car for a couple of days and see if the error comes back. I will also try and look into INPA. What should I look for?
Hi. im from South Africa. I have a 318ti fitted with a e90 n46 engine 4 cylinder. I am currently having endless issues with intake cam moving off timing. i replaced the bolts even but the camshaft moves and the gear remains still. any ideas why?
I have setted timing numerous times and it still does that. please assist.
Very good video. I suspect the exhaust vanos unit to be worn out also, u must check it and make a video, also test the vvt motor and eccentric shaft sensor
I will probably make some more videos on this problem. VVT motors should be OK because problem is only present ont 4th cylinder, the vvt sensor is quite smart and has redundancy + parity bit check so it would trigger an error code and emergency mode if something would be wrong with it...
Thanks
Can you tell me why my 325Ci 2001 BMW doesn't have th 3 bolts you took out of you Main saft to remove the pully.?
Also do they sell the crankshaft holder for this style setup.Please let me kmnow I am trying to replace the chains and want to change the oil pump chain as well.
Your video was great up till the pully removal. Thanks Lots; Ms. Jillian
All my videos on chain replacement and vanos units are on a N42 engine. I think you have the M54 engine..
Hi. Thanks for the video. Could you please clarify in what positions the vanos should be? I’ve noticed your inlet is just under 120 and exhaust 55. I’ve got 120 inlet and 120 exhaust. There’s no faults in the Ecu but it has rattle between 2500 to 3500 rev when warm. Any ideas?
Many thanks
Did you use INPA to scan the car and check VANOS timing?
@@BimmerZen yes
@@BimmerZen yes I have used INPA
@@damok9529 did you figure it out?
Hi , I've recently replaced chain, tensioner and guides, the car is running rough there is a vibrations that can be felt on the steering and seen on the review mirror. The mechanic confirmed that the timing is correct, when using their diagnostic tool no codes come up. When using INPA I get 2782 camshaft pickup outlet. However the logistics and error counter are both 0. They've clean the solenoids and still does not help.
Please assist
good video :D
hello i have a bmv compact n42, if you are in the mood i answer i have a question in the bey of my n42. Cold Star fires without a problem on the key. It reaches the operating temperature and drives normally, the engine can run without problems for a couple of hours. But when it goes out and then after a few minutes or half an hour it is harder to light, it has to spin more until it is assembled. So when the motor is harder to start at operating temperature.
I had similar issues when chain jumped for 1 tooth on the intake camshaft... You can check my videos on replacing the chain (ruclips.net/video/Pi9fWWNf0gA/видео.html).
I would first do a compression test when cold and when hot (when it wont start). You can also check for VANOS position with INPA to see if your intake camshaft is in correct position. Correct intake position is arround 120 deg (+/-5 %). Also, dont forget to check for error with INPA.
@@BimmerZen I'll take a good look, it's mostly semi-general. Worked cylinder head and compound engine and tool serrated.
I also have issues with 4 cyl. Before repair and after repair. I think it's ok
Rough running? Misfire?
@@BimmerZen all ok except the rattle (next comment). But this rattle I have since 2013 when I bought this used car and it was before me.
@@BimmerZen Also raising knock values at speeding up. To 5 in fourth cylinder.
Hola mi amigo y que programa usas para borrar las fallas y tambien se puede hacer aprendisaje de topes de valvetronic con ese programa y donde lo consigo ? gracias
Thanks much for ur time spent making this video to help us I for sure appreciated it very much because I have one of these engine working on question which impa your using it seems I have to get me one of those too
I use some older version that i got on the CD with the OBD cable. I'll check...
@@BimmerZen OK thanks I check some out on aliexpress so far its a pity I am just knowing about this tool I bought a autel ap200 last month and a Delphi e150 from alipress I like the Delphi the autel didn't awe me at all using it on the BMW
@@vinotec4136 a lot of generic code readers dont read all data on the ecu for the N42/N46. Probably because these engines were was not present in the US market.
@@BimmerZen well the autel and the Delphi read codes in each computer the autel couldn't relearn the value tropic motor I didn't see the option for it the Delphi tried to but a bad essentri shaft sensor preventing it from completing the task
Is this the same for the n45b16 engine? It’s got similar symptoms to yours
Yes.
Hola excelente video, consulta tengo un 320i año 2006 motor n46, está con problemas de vanos, es posible reparar los vanos?
I can only recommend replacing VANOS units, not worth repairing them.
Hello.
What can be done with the valve under the oil filter?
When I replaced the oil filter housing seals I didn’t see anything special.
Thanks.
There is a check valve inside the oil filter housing, but it's not replaceable as far as i know. You could remove the oil filter housing and try to inspect and clean it if you suspect there's something wrong with it.
@@BimmerZen Hello.
I took out the spring and stretched it a bit, now it closes stronger, it turns out it works?
Hello, is it possible to send the STL file to the device for 0.6 NM or to buy a ready-made one.
Hi, contact me on bimmerzenchannel@gmail.com.
Have you inspected the condition of injector 4 ??
Yes, I tried swaping injector, spark plug and coil to other cylinder, but no change...
hi again zen :D i recently got my inpa to work and my adap inlet is 121 now i havent recet de adaptations altho i havent done anything but timed the engine when i did the chain . my outlet is 57.9 but i dont know if that is whitin spec. what do you think could be the issue? my cylinders are -0.27(1) 0.14(2) 0.00(3) 0.13(4)
I did some testing and I can reproduce the >120 deg on the intake camshaft by aligning the front VANOS locking tool 0.5 mm to the left (exhaust) (reference point is the edge of the cylinder head). So I think this happens because there are some tolerances in the locking tools and placement. Just keep this in mind if you do the timing again at a later time and try to align the front locking tool a bit more to the right (intake) side. This will probably show up as an intermittent error code in INPA about intake VANOS being too advances, but I don't think it's problematic for the engine.
The rough running data looks good. I assume the the max value in your INPA is 200 and if you disconnect a coil you get about +20. So your relative rough values are well under +/-10% which is the point where you have a problem.
@@BimmerZen hmm ok so you think this has something to do with the timing i did? you dont belive the stepper motor could cause any of it ? also i dont get any codes for it but there is a ! ifront of the number. but thanks for the info man!
@@magnus3885 ! in front of the number is because max is supposed to be 120. Valvetronic (DC servomotor) does not play any role in determining the camshaft timing.
@@BimmerZen oh ok btw i read a manual on timing job and chain replacement yesterday and in the manual they removed the vacumm pump and twisted the cams to make sure they were locked could this be an issue that even tho the vanos units are ok they arent locked ? that you just have to turn them abit inorder to lock? if so that could probably have something to do with it i did not check if they acually where locked . I still get ocationally a rattle on a cold start for like 3 secs.
bmw e90 320i has problem with high co2 after new chains change
How to know if these are bad ?
Have you already solved the issue related cylinder #4 rough running?
I have done some testing and videos, but I never got to the bottom of it. I then stopped driving that car, so now that video waits in the RUclips limbo:)
I only have this Coldstart rattle which goes away when the Red Oillamp goes off. I think it has to do with Oilfilter House Gasket Valve. If i delete Adaptations the rattle is going away and comes back in couple of days or weeks why? Some people say this Coldstart is normal for this Engine but i have it every morning now!
What engine do you have, N42 or N46? Do you get any INPA error codes? Red oil lamp could indicate very low oil level or bad oil pressure sensor.
I don't know how deleting "values" (adaptations?) could have effect on startup rattle. It's seems more like an oil pressure/flow issue or worn/defective VANOS unit issue. Could also be slack chain due to broken chain guide or worn chain tensioner.
The rattle is "normal" in the sense that a lot of cars have this issue but the engine works fine otherwise. Probably worn VANOS units drain over night and they need to be pressurized on startup to stop rattling. My opinion is that if the rattle goes away after 1-2 seconds and it doesn't get any worse over time, it's not worth worrying about.
I plan to do some test on my car to get to the bottom of the rattling issues on N42:)
@@BimmerZen I have the n42 engine. No error Codes. It always Happen if I Park upwards. On flat surface it's not Happening. Even tho if it's Happening on flat surface IT isnt that loud or long. Otherwise it's all good I guess I need an 0w40 0w30 oil. Im using 5w40 full synthethic oil
yo billerzenn wanna give me some of you're wisdom? so i changed the chain and everything but resently after maybe 1k km it started to sligtly rattle sometimes why do you think this is? also during idle the engine makes some random noices like it changes something witch i think is the vvt but it sort of clunks when it does it and also pretty freqvently i dont recall it doing that before im going to have a look under the cover this weekend but could all of this have to do with the vvt or what ?😅
Sure sounds like VALVETRONIC issues. If you don't have any error codes, then I would suggest you remove the valve cover and inspect everything. Especially the rocker arms, intermediate levers and valvetronic springs.
@@BimmerZen y gonna have a look
This engine is very troublesome but can last a long time if well taken care off.
Yeah, oil services are sooo important for these engines.
Hi I am Wennie Dr Philippines I would like to ask about the cooling fan my fan is not working can you give an idea why the cooling fan is not working and I can't locate the right fuse and relay on the fan connector I can't see elec.current in one of the big wire I'm using my multi meter and I can't find any current on that wire can you give me idea on this matter and thank you so much....
You should open exaust vanos unit, that one get more demage. I open my 2 years ago, it has much worn out, i had to change it. Inlet vanos was ok. Rattle was comming from exaust vanos unit
Uradjena je polu generalna motora a za vanose nisam otvarao .
Yeah, that is what I have read and heard. I want to solve this steb-by-step and just see what happens at this stage. I'll make a separate video about the exhaust VANOS unit. This video is already a bit long:D
I think mine is the same situation as it was yours. A diesel like sound when operating Vanos exhaust unit. Already checked the solenoids and swap them. I'll open again the head cover and almost certainly change the exhaust Vanos unit. Hopefully ther is no damage on the camshaft due to the rattle/malfunction of the Vanos unit.
Also, start up rattle. Problem was broken plastic part from oil dipstick into oil filter housing. Plastic part was stuck into valve insde oil filter housing, and oil get down to the sump. I changed spring inside oil filter housing just in case. That solve my problem
@@dejanlalic1340 Sounds like a hard problem to solve. Thanks for sharing the fix!👍

My inlet vanos is 120 degrees
But my outlet vanos is 59 degrees instead of 55 like your , what does it mean ?
Well, let's look at it like this: VANOS sprocket has 38 teeth, which means if the chain jumped on the exhaust side for 1 tooth it would result in 9.5 deg of offset in any direction. Usually chain jumps in to retarded position due to engine rotating clockwise. The N42/N46 engines are known to have this issue with the VANOS position drifting towards the retarded position, like in my case where I have my intake at 119 and exhaust at 55 deg. If 60 deg is correct position, then my 55 deg is 5 deg retarded, which means an 8,3% error, which is tolerable (above 11% will trigger a code). I think there is probably nothing wrong with your car. If your engine works without any issues and there are no error codes, then I would not worry too much about it.
I did not find any reason of this 55 instead of 60. But 59 is better than 55.
I have 2a6f code. What could it be? Valvetronic motor, eccentric shaft sensor or something else ??? Car feels slow at lower rpm. Btw good videos :)
I tested valvetronic motor and it seems to be working, but i dont know if it works correctly.
@@E90dga Definitely some VALVETRONIC issue. It's probably not the sensor, It's quite smart and it throws other errors when faulty. I would suspect valvetronic servomotor or valvetronic bearings. How did you check the valvetronic servomotor? There is a procedure to test if the valvetronic eccentric shaft has correct tension (www.newtis.info/tisv2/a/en/e46-316ti-com/repair-manuals/11-engine/11-37-variable-valve-gear/1VnYMYhkMF -> free registration required). Did you try scanning with INPA to get more data for this code?
Imate kakav kontakt broj ili mail? Imam problem sa N46 motorom i nikako ne uspijevamo otkriti što je pa možda možete pomoći? Dok je hladan upali na dvije sekunde i dalje ništa, čuje se dok se pali kao da motor opšte nema kompresije. U tom momentu se motor zalije sa benzinom. treba ga ostaviti i ako se dugo starta, nakon dosta vremena nekako upali al neravnomjerno radi i ne prima gas. Motor je u fazi dok je hladan. sve senzore smo probali al ništa. sumnja mi ostaje jedino na vanos
Why did your EIN vanos not lock??
I'm still not 100% sure why. I suspected clogged locking pin so I cleaned the whole unit.
@@BimmerZen Thanks for a quick answer! Awesome channel. I have AUS vanos that was not locking. I dismantled it but found no evidence of that. I have placed a new one. I watched your video when you assembled the head of an engine, but you did not check the valve timings after screwing the bolts. Or I missed it. So after cleaning is it ok? Also did you try to lock in place your old one?

The n42 vanos looks much less complicated and less expensive than the system on the m54 motor.
In the next two months I’m swapping my n42b20 engine for m52tub28.
This video just made me wonder if this engine is worth a swap 🤔.
