c220 Air Mass Meter, need Help
Hey guys, my car's AIR MASS METER is now dead. Car's running bad, horrible idle, even shuts off sometimes at intersections. I'm getting about 350 kms to a tank of decent highway driving at 80km/h. I was wondering if anyone has any creative idea's to make a last ditch effort to see if I can save my air mass meter from replacement, perhaps a quick fix, or a temp. one. Please let me know.
Secondly, incase i do have to change it ASAP, since it is an expensive part; does anyone know any place i can get the best bang for the buck on one? I don't know if getting a used ones even an idea to ever consider, since this is a known problem with many c-class mercedes. So if you guys can let me know about a great deal anywhere, or after market solutions, that be helpful. thanks. |

have you checked the price at FASTLANE which yiu can link to from the tab on top of the mercedesshop page?
I haven't heard of anyone fixing an AMM, it may be that an element gets depleted and is not repairable. But I would guess there is a trick way to bypass the AMM, but not better overall performance. do a search on this site cause I think someone bought an AMM from e-bay and it was a problem. have you pulled the codes from your OBD-II, do they have OBD-II on canadian C's of your model year. |

I purchased a mass air meter off E-Bay without problem. As with any purchase watch where you buy. Select a long time seller with good feed back from purchasers.

hey ethan, thanks for your response. Yes my car does have an OBD II slot for read in. My friend has a cheap one and it told me my AMM was the problem. So I went to my Euro Mechanic, and put it on his mercedes cert. computer, and I was told my AMM is gone. However, they never give me the codes, just tell me what parts are not functioning properly. This is the only information I have. My car's been idling roughly lately, and sometimes so low my car will shut off. Sometimes while I drive even. I've been told my AMM is not functioning properly and it will cure the problem. I hopet his is it, what you think? thanks

when my AMM went bad - for my American market car my CHECK ENGINE LIGHT came. However the AMM went bad first and the CEL didn't come on until about a 100 miles latter.
My AMM symptoms were most noticeable during rapid acceleration, I was getting very jerkt transmission shifts. Since the AMM's seem to have a finite life it is worth changing out, yeah some techs say don't replace anything that's not broken, But this is your own car and you don't have to explain things to a customer. There were some posts explaining in detail how to read OBDII codes that indicate a bad AMM and verify in fact that the AMM is the culprit, And some people have had the AMM codes activated without going through the diagnostic procedure to verify a bad AMM and when they changed out the AMM that didn't fix the problem - though that is rare compared to bad AMM's simply dictated by the OBD II codes only and fixed with a new AMM. So when yoy get a new AMM use a good trusted source like FASTLANE or a local dealership and be leary of e-bay, because a used bad AMM taken out of a problem car can be easily cleaned to look brand new |
