Vanos sound. - BMW Forum

zeaq · 05-15-2006, 01:43 AM

I did a search function in this forum regarding the vanos noise. I know it makes it ““click click click” noise at the vanos area. But none of the past topic answered this question. What if I just ignore the sound and live with it. Can it damage the engine because of the vanos sound?
I have list of what to do with my car in July. Like 1) AC tensioner
2) Replacing the B- pillar
3) Centre AC flap
All those parts are pretty expensive and I have no money to cure the vanos sound!!

Thanks in advance

JUst to clarify to everyone else: what you are replacing is the plastic cover on the b-pillar.

Now, regarding the VAnos noise: have you kept up with the regular maintenance? Oil changes, filters, etc.? Whe I bought my car, the salesman told me that most of the time, the vanos would get noisy when something simple like that was long overdue. SOrry I can't be of more help. I will do a little research. Do you have the Bentley manual?

Plastic B pillar costs me $160 = roughly $100US is cheap for you huh? Damn you rich people.

Anywhere back to the topic,
I follow the BMW dealer maintenance procedures. All have been change on January 2006. I have the downloaded Bentley manual. I’ll read it later. The noise is gone after driving for a long distance and stops at idle.
The noise it not that loud unless someone nil down and hear the engine.

I am sorry. I still don't have any better help. I checked the Bentley manual, but didn;t find anythihgn too useful.

Hey, I didn't say that the b-pillar cover was cheap. I just wanted everyone to know that you weren't taking apart your frame and replacing the actual steel pice that is the b-pillar. US$100 -- ouch!

The noise is the solenoid starting to die. That happens.

WarNox · 05-15-2006, 06:25 AM

the cover of the B-pillar on the inside or the metal things on the doors on the outside? and how come?

Can you tell me, what's the part number or the part name so i can see realoem.com to see how it look like and call the dealer for the pricing.

Thanks.

Often enough changing the vanos selenoid is the answer to a lot of the noise... it wont kill the noise all together... but it will help it... the noise is coming to be known because of the chain tensioner is getting old in our engines... the clearance for the main vanos chain is very minimal.. thus allowing it to rub the vanos case...

Unless your chain inside there is extremly loose... there shouldnt be a problem with the noise... its natural...

Good Luck that is my opinion... I have the noise too...

My car has only 26k miles on it. I guess it's been garage from 97-04 by it previous owner is no good then. Engine starts to wear from from lack of usage?

well here's what I would do. Replace the Primary Timing chain tensioner and the Vanos solenoid. (those are their names when you look up the replacement parts)

While it's highly unlikely that the VANOS solenoid could go bad regardless of usage, the tensioner can It's a spring, it's working hard whether or not the timing chain is moving, which means even when the motor isn't running, it's still wearing.

+1 for the spring tensioner. Basically your chain inside your vanos unit is becomign a bit loose due to time and miles so now your chain is smacking the inside of your vanos cover.
