Mercedes-Benz C-Class Maintenance and Repair

    If I were you, I will press hard on MBUSA to "buy back" the car as a "lemon". Basically, you should get a new car as replacement, IMHO.

    just bought a 2002 c230 coupe and the service B indicator came on, can anyone tell me what its for and what to do about it? Also my check engine light came on and the readback was a problem with the secondary air injection pump, having a problem locating it and what does it do?

    Can anyone shed light on a vibration problem with my '97 C230? I've had it for a year now without any problems other than there is a constant vibration whenever the engine is on. I constantly feel like I'm sitting on a vibrator pad the entire time I'm driving, whether at 20mph or 80mph. I have had the mass air flow sensor replaced, new tranny mounts, new engine mounts and everything from wheels to axels checked for defects. I do have Michelin tires, and I have read discussions about the flatspotting, but I don't think it's that because I had the same problem with the previos Cooper tires. ANYTHING ANYONE can share would be appreciated. I love the car, it's in showroom shape at 82k miles, but I sure would enjoy driving it better with a smoother ride.

    You hit the nail on the head. After three plus weeks of changing so many parts, I lost count. The bottom line is the problem was resolved by shimming the rear axle. Picked up the car early this morning and it runs great. Hopefully the problem will not return. My dealer, Mercedes Benz of North Haven Connecticut, never gave up and worked hard to find a solution. Best dealer I ever dealt with.

    shimming the rear axle entails, but it's good information to have in our "database". And I'm glad everything is okay now.

    Thanks for your input. I notice that you have a 2005 model. I wonder if shimming the axle would help my '97 model? Do you have the name of the Service Manager or your mechanic at New Haven MB? I live in Atlanta and, if necessary, would like for my dealer to be able to call yours to get some input. Sometimes sharing info helps the guys figure our how to solve things. My service guys here, too, have been really great about trying to solve this, but we've run out of soulutions.....

    did you ever find out how to fix the problem. i have the same exact problem right now. any help is appreciated...

    Even though your subject says "battery," I'm assuming you mean you have a vibration problem since you responded to my post. No, I haven't figured it out. It is worse sometimes than others. Somedays, I hardly notice it. Others, I feel like I'm on a vibrating bed in a cheap motel room. I have had 3 dealers and a private Mercedes repair guy look at it, but no one can fix the problem entirely. I don't think it's wheel/tire related because of this. When I have my foot on the brake, there is no vibration, but the SECOND I let up on it - even if I am barely rolling - the vibrations start. This led me to concentrate on the motor and tranny mounts, both of which are brand new. I don't know what to do about it. I love the car. Mechanically, it is in super excellent condition according to anyone who's ever had their head under the hood. It looks brand new inside/out. I just wish I could figure out how to stop the vibrations......

    I recently became a used MB owner frustrated by an intermittent starting problem until gas cap removed with a resulting noise of pressure release, and then the car starts readily with the cap refastened. What gives? Any help appreciated.

    Sincere thanks,

    Don't have a clue. Never had or heard of this problem. Are you putting premium gas in the car?
  • lipplipp Posts: 58
    I think, but I am not 100% sure, that your problem is with the gas cap. It does not vent properly. Try replacing it. I had a vehicle that the check engine light would go on periodically. The dealer determined it was caused by a poorly venting gas cap. Once replaced the light never went on again. Worth a try......
  • Driveshaft and joint vibrations may be caused by faulty transmission valve body or torque convertor(?).Also check in coolant reservoir for floating trans fluid! Where is vibration felt?
  • Gas tanks no longer vent through cap. Check charcoal canister.
  • lipplipp Posts: 58
    The car in question is a '96. Problem seems to go away when cap is released. Did gas tanks vent through caps in '96??

    There are two release catches at the front of the overhead panel. Look for two metal tabs on the windshield side, press them in and the panel will drop down. Be careful when taking the aspirator blower fan
    from the overhead panel.

    Periodicaly there is a loud pop from the radio, the radio and navigation system shut off and the display goes black. About a minute later the radio will be back to normal. Has anyone experienced this problem?
  • Several times a week, the car will not crank on the first several attempts. It tries to crank once and then stops. Occasionally it has taken as long as 2 or 3 minutes of cranking before the car will start, but it always eventually does. I saw the posting above and tried opening the gas tank to no avail. Has anyone experienced this before? I would appreciate any advice I can get. Thanks.

    I am having the same kind of problems, i have a C280 1999 and am experiencing the same problems. I first thought that it could have been a bad fuel filter, i changed the fuel filter but still have the same problem. it happens intermittantly like once a week or something.. IF u got your problems fixed lemme know... thanx

    My MB is partially DEAD! There is a funny noise in the tranny. The car still shifts but im afriad to drive it. i towed it to mechanic but he cant come up with the perfect solution. he says that he thinks that the transaxle is out, and at the sametime says that i should bet a new tranny. im stressed out coz i dont know what to do. Can you guys help me out.? The computer doest show anything wrong with the MB. It has 130,000 miles on it.
  • I own two 190 E Mercedes, in both the alternator was over charging and boiling the battery, then the car wouldn't start when it was cold unless you poured gas into the air intake and warmed the engine up, then it runs fine. The overload relay located behind the car battery has a 10 amp. fuse in it, the fuse is blown and you put a new one in and it blows immediately again. Does anyone know what the problem could be? :confuse:
