Mercedes-Benz C320 Recall 08V303000

Incorrect Software Calibration May Cause Fuel Pump to Remain Powered in a Collision

Recall Details

There is a faulty software calibration that affects several areas including shutting off the fuel supply in a collision. This could cause a fire hazard during an accident. Dealers will reprogram this software. The Mercedes-Benz recall number is 2008 070001. This recall began during August, 2008.

Our Quick Take

There are several computers in the vehicle and each computer requires proper software to operate the each vehicle system. One particular software calibration on this vehicle was erroneous from the factory and could keep the fuel system powered after an accident. This can cause fuel to continue to flow even after an accident.

What Should You Do?

Please contact your Mercedes-Benz dealer. They will check to see if your specific vehicle is affected and advise you on what to do next. Always have your vehicle identification number (VIN) handy when you call.
