Seat control module failure. 2 modules per car, 1 for passenger seat, and 1 for driver seat fail. The defective seat control module unit will deplete the cars battery overnight resulting in a no-start condition the following day. A new battery, or a jump start, will get the car going again. The common immediate resolution is to unplug the seat control module which would impact the seats ability to respond in an accident. The replacement part and diagnosis from mb dealer is approx $700/ module. This is a huge liability for Mercedes owners and the repair should be investigated for seat function safety. I understand the part number has been updated, which I believe is an admission by Mercedes that the original part is defective.

The contact owns a 2005 Mercedes Benz Clk500. After refueling the vehicle, the fuel level gauge displayed an empty reading and the check engine light would illuminate intermittently. The contact stated that there was a recall under NHTSA campaign id number: 08V303000 (electrical system) but the manufacturer stated that the VIN was not included. The vehicle was not taken to the dealer for diagnostics or repairs. The approximate failure mileage was 113,760.

Driving home from the grocery store on a surface street at approximately 35 mph. Engine switched off along with everything electrical. Car did restart and I was able to get home. Attempts to restart after that failed. The remedy was to replace the electronic ignition switch (ezs or eis control module). The explanation I received was that it has certain computer circuits that affect not only starting but other car systems. In fact, incorrect programming of the replacement module caused me to be unable to lower the soft-top as if one wasn't installed. Reprogramming the unit to "tell" the new module that this vehicle isa convertible solved that problem.
