Looks like everything is pointing to a fuel pressure check.

What dissapoints me most is the level of expertise at Mercedes Benz dealerships. William Auto World in East Lansing, MI has recommended changing the ECM after getting Code 35 (Mixture lean) without check the Fuel Pressure!

Rock Hill Imports in Kingsport, TN just changed the Wiring Harness, and informed me Friday that they could not cover the wiring harness under the goodwill policy, after talking to the factory rep, due to the age of the car! Delarship in Atlanta has done this for hundreds of cars. I will have to talk to the factory rep myself. Wiring harness did not need to changed at that time, the ECM Code has not changed.

I gave Rock Hill Imports the print out from this FORUM on the LH ECM, mixture too rich, on the second visit for the same Check Engine Light problem, and the tech concluded that changing the module was the the correct diagnosis based on DM CODE 19, wihtout realizing that LH is different from HFM! and no other testing.

I requested them to change the Aspirator Motor for the climate control and they changed the Cabin Temp Sensor, I had to tell the service manager Grag Durham where the motor was and he agreed to refund the labor and parts for the sensor change. Aspirator was on the service requested form for the Tech!

I had requested Williams Auto World East Lansing, MI to change the ACC cabin filters and they informed me that my car had did not have any!! They did not know that the filters are located below the windshield wipers.

Both the dealers above handle both Mercedes and BMW. Hard to believe!! They should have checked the fuel pressure after getting the code from ECM. None of them did, $2200.00 (ECM Change) MI dealer, I declined, and $884 TN dealer (wiring harness) which they did, and it did not solve the problem. If I had know about the harness issue, I would have gone to the Atlanta dealer and got it replaced under the Goodwill policy, but at that time, I was not aware of the this FORUM.

I would like to thank everyone on this FORUM again for the help and the information data base that has been created.
