Emission Control Problems of Mercedes Benz E Class

The contact owns a 2000 Mercedes Benz E Class 320 wagon which was purchased used in March 2003. He stated that while driving at speeds of less than 40 mph, the contact thought he had run over something and there was a violent vibration in the steering wheel. Then, while making a left turn he could heard a grinding and thumping sound coming from under the vehicle. He then noticed the front passenger's side wheel was actually inside the wheel well. The vehicle was towed to the nearest dealer where they found the front passenger's side coil spring perch failed causing the front end passenger's side of the vehicle to collapse. The current and failure mileages were under 130,000. Updated 01/19/10 the air mass flow sensor and outer tie rod were replaced. The lower ball joints were worn and were replaced. The crank sensor was replaced. The engine was consuming large amounts of oil. The dealer stated the vehicle needed new rings and a valve seal. The transmission would slip during cold weather conditions. There was an internal fault with the clutches. The gear shifter had excessive play. The left window regulator had to be replaced, because it would not close. The left rear door latch was inoperative. Updated 01/20/10.

The purge value for the emission control system, makes a tapping noise in the engine at idle, as if the car is low on oil. When I took this in to the dealership to see what the tapping noise was, they explained that a loud metal tapping noise was normal on the mercedes. They stated they would put a new "purge value" in the car to see if that would quite the loud noise in the engine. Upon doing so, the car began jerking back and forth violently when attempting to accelerate. The problem becomes gradually worse, the check engine light comes on, the car begins consuming large amounts of gasoline (about 8-10 mpg), the car will rock from side to side at an idle stop and will hesitate for 10-30 seconds, when attempting to accelerate from a stop.
