E320 (w210) bad vibration when idling
Hi, not sure if anyone can help me on this one. I have a w210 chassis (E320), 1998, 64K miles. A while back, I had noticed my car had a bad vibration coming from the engine. TOok it to the dealer and he replaced the harmonic pulley that was on recall. Seemed to go away. However, I noticed after an extremely long drive this weekend (from the Hurrican, was on the road for 17 hours, about 13 of it stop and go) that when I have the car in DRIVE and it is stopped, there is terrible vibration. Everything shakes, steering wheel, seat, you can really feel it and hear it. But as soon as I gain any amount of speed, the vibration COMPLETELY disappears. Also, the vibration is not present if car is in Neutral, Park, or Reverse.
I drove the car for a little while and after a while, the vibration seemed to go away. However, it returned again this morning. This seems odd to me that it would vibrate only when stopped. Seems like it should vibrate all the time when the car is in Drive. Could this be the Engine Mounts? Also read that it *might* be the air flow mass sensor, but wasn't sure on the specifics, never mentioned only vibrating when stopped. Woudl taht cause the car to vibrate only when stopped and in drive? Its pretty bad and pretty rough. I have to make the trip back to Houston and am a little worried that I may not make it. I took it to the dealer about 2 months ago and got back a laundry list of problems. For the air conditioning they quoted $1000 which looks like will get fixed by me for $150. I knew when they were charing $100 to change the air filter, that MB was a ripoff (not the charcoal filter even or the dust filter, the air filter).
Also, on a side note, I've been pretty disillusioned w/ my E320. Suddenly, it seems to be having many problems inlcuding air conditioning problem (which I bleieve I found the solution on other posts on this site).
