@@gottgaame Hi MJ, Usually for this vehicle timing chain stretch and sprocket wear causes the timing chain to jump time. But if just the exhaust was out a tiny bit then it may be from the factory that way. If it was off a lot then most likely jumped time. If timing is good and you have a vanos fault it can me the vanos unit, central bolt , or Actuator. Also if the oil filter center insert is missing you can get vanos faults.

Hi Phuong, Yes you would have to remove the oil pan and lock the counterbalance shaft. The sprocket for the oil pump should also be replaced.

Great video. In fact there there is one lingering question. On my n20 the LOCK pin never really goes in flush. Flywheel doesn't move and is about a 1/4 inch to the elbow of the pin. Is that the typical fit? And are there other holes the flexplate has that could account for and error 131501 after a solenoid change?

@AskTheCarExperts

Hello Tino, The N20 I believe only has one hole but you can get caught on a flywheel seem and not timing correct. One trick is to shave the end of the tool slightly so it goes it easier. Also use a bore scope to check you are in the right spot. In addition if the timing is close you can use the cam bar codes to help identify when you are approaching the correct spot.

Thanks for this Great informational video. On my N20 the plunger on the VANOS central valve bolt is broken. Therefor the actuator is not pressing on anything. Would it be possible to remove that bolt with the plunger without having to remove the valve cover and having to set up the timing chain lock ? I’d appreciate if you can reply to me. Thanks

Greatly appreciate the vid I just did the whole kit + turbo on an x drive ooooboy. Now my intake Vanos is going crazy. It’ll start at 0 deg and end up at -60 deg then sets a camshaft jammed code and shuts off the turbo. I’ll pulled the valve cover twice, swapped bolts, solenoid and sensors Timing is dead on with tools. So now I’m suspecting the cam phaser is locking and not letting go. Exhaust Vanos bounces around 0deg. I’m beyond heartbroken. Bought the car with bad turbo and knowing it would eventually need a chain. Before 100% of the time the car would go in limp mode due to low turbo pressure so I’m thinking the phaser never actuated much past base timing so it didn’t show Vanos fault then.

Which then confuses me of how I set both cams and know it’s tdc? I get the vanos will adjust its self to the sensors but how do I make perfectly sure the plate to the crank to the cams are all perfectly in time?

If you're only adjusting the timing, do you need to remove the chain tensioner? On the N43, the central VANOS bolts are one-time-use only so they'll have to be replaced. I'm just thinking if the tensioner is still in place, the VANOS bolts removed, would that push the VANOS gears making it difficult to put the new bolts in? Thanks.

@AskTheCarExperts

Hello MartiansChronicle, There is a work around for removing the tensioner. You can carefully depress it to release the oil pressure and this relieves some tension on the chain when doing timing. Or to be safe back it out most of the way to release some tension.

Hello, You should be able to tell if your timing is off just with the timing tools and verifying TDC and the cam locations with the crank pin. I did run into a car that showed low compression on a new engine but it was just from it not being run in a while and once it was fired up it was good.

Have you ever torn into a VANOS unit to see if it's possible to thoroughly clean one and examine it for excessive wear? I see a lot of people just replacing them, but damn they are stupidly expensive. Are the VANOS units like a tape measure or a tube of toothpaste? If I pop the screws out and pull the cover off will the very thick spring go 'boinnnnng', slap me in the face like pulling the nut off a McPherson strut assembly and totally ruin my day? I had one of the notorious N26 failures for both the chain guides and oil pump so my motor was full of metal glitter. Darn near the only thing I didn't replace was the VANOS units or the solenoids. The solenoids were very easy to rebuild, but I just ultrasonically cleaned the VANOS units, oiled them and reused them with all new OEM timing set. Now I have a good running engine with almost a dozen codes for VANOS issues. Performed re-calibration tests with ISTA and still get errors. Ran some ISTA tests and they never are set to what the DME expects and wont adjust fast enough.

@AskTheCarExperts

Hello, I have seen the VANOS units come apart when the bolts holding them together either walk out or the heads break off. I think they are keyed internally but this is not something that has a repair procedure. On N51 N52 vehicles the dealers would replace just the bolts on some VANOS units. They have to be replaced one at a time and cannot exceed a specific torque and torque angle. Sorry to hear your N26 had the timing chain issue. Make sure you have the insert in the oil filter. If that is missing you can get VANOS faults but you may need to replace the VANOS units with new parts. Hopefully your engine is running clean and the metal glitter ( aluminum shavings) have all be cleared out.

I recently did a timing chain replacement and brought the car back to life, but now I am getting codes: 130F20, 130E20, 120408 and miss fires in cylinders 2 and 3. I reset the codes and had the vanos relearn the new chain. Now I have codes: 164040, 164041, 120408, and the misfires (no rough idle anymore) I followed a different video before I found this one, and they torqued the sprockets first before they put the tensioner on. So I believe my timing is off, my question is do I have to do the whole process again (remove engine mount, oil pan, take off Jesus bolt, etc.) or can I just readjust the camshaft sprockets the correct way? Thanks in advance!

It was a little off but man couldn't get no adjustable wrench in there. Think I used a 7/8 wrench and made it work at a angle. Would you recommend a certain size or special tool? Can't get in there with a adjustable wrench. But that's not the question I have. I have everything taken off now. Got it at TDC but when I was was trying to get the oil module at TDC as in the fcpeuro videos. Says to turn clockwise n should hear a click or so but I never heard anything so I just kept turning n turning. Never did hear anything it just spun n spun. So I just lined up the holes and used the specialty tool n took the oil module off. So how do inknow if its in the right spot? I used that little tool. I'm sure you know what I mean. I just don't wanna put it all back together n the oil module nit be in the correct spot. If you could help I would appreciate it so much.
