Check Engine Light On Problems of Mercedes Benz E320

Crankshaft position sensor - the engine shuts down without any warning, sometimes while driving at speed. I tried to restart it several times, but to not avail. It may restart after the engine has cooled off (after 20-30 minutes) but the problem repeats itself when the engine has been running and warm again. The check engine light came on and a malfunction message: battery protection - conventional functions temporarily unavailable displays. Once at the repair shop, the mechanic knew what the problem may possibly be even before testing for the check engine code. He said he's seen this problem for quite some time. The problem code did come up with a bad crankshaft position sensor as he predicted. I researched this problem on several Mercedes Benz owners’ forum web sites and discovered numerous entries from owners with this exact same problem, affecting several mercedes model years. I called Mercedes Benz and asked why a recall was not issued for this problem and what they were doing to compensate owners for the repair cost or at least a notification of this problem. I did not receive a favorable outcome but was told by the customer service representative that she would escalate the issue internally so that they would be aware of the issue. I believe that Mercedes Benz has known about this problem for years and it continues to affect many owners. Having the engine shut down with no warning is very dangerous especially if the car is being driven at speed on the highway.

Tl-the contact owns a 2003 Mercedes Benz e 320. The contact stated that the check engine warning light was illuminated. The vehicle was taken to the dealer where they advised her that the two valves and the sending unit failed and needed to be replaced. The vehicle was repaired. The failure recurred a few months after the repairs. The manufacturer was contacted and they offered no assistance. The failure mileage was approximately 91,000. The current mileage was approximately 92,000. Kmj.

My 2003 mercedes E320 engine stalled momentarily as I sped up to enter I-95 near fredericksburg, va. I eased up on the gas and it restarted with no apparent immediate after effects. Fortunately, there was no traffic close behind me, or there might have been a collision. There were no warning lights showing on the dashboard before or after the stalling. I continued south on I-95 with no further problems until I exited at ashland, va. At the interchange with us1, when I stopped at the traffic light, the engine stalled out and would not restart, blocking traffic. A policeman arrived and called for a tow. Again there were no apparent trouble lights. The car was carried to the richmond va dealer, which replaced the air mass sensor. This corrected the problem. I reported this problem to mercedes customer care in NJ. I emphasized the seriousness of having the engine stall out, but they were not planning to perform any new fix. They said it was "operating as designed", making reference to a "limp home" feature that stalls the engine and warns the driver to get off the road. I looked in the car's manual, and the term "limp home" appears only once concerning the engine. However, there is no description of how this works or what the driver is supposed to do. In my car, the engine did not "limp", but ran at full power after the stall and restart. In my opinion, a sensor failure should not disable the engine, and any serious problem should be warned through a blinking check engine light. Mercedes needs to remedy these problems through a recall. At the very least, owners of these cars should be warned about the potential problem, and how to deal with it if it occurs.

: the contact stated the check engine light illuminated while driving. The vehicle was taken to the dealer where it was determined by diagnostic testing the air mass sensor needed to be replaced. The contact stated also owns an ml320 which had the same failure July 2006. If the air mass sensor is not replaced, further damage can result to the engine.
