Common problems with the S550 engine computer

Name: Alex Flores
Email:
Year: 2008
Vehicle: Mercedes S550 Ecm ecu problem

Question: Hello, I have 2008 s550. I Just found out the ECU needs repair. When the vehicle is cold it runs like a champ. When its warm or Ive driven it for 20 to 30 mins my vehicle will not start. Lately Ive found it helpful opening the hood and lightly hitting the ECU and apparently that works perfect. Please give some enlightment to my dilemma. I've Taken it to dealer and spent over $3500 in repairs and now they say another 1400 for the m.e. control unit. Dealer replaced: crankshaft sensor, aux battery, fuel throttle, fuel pump, fuel relay, fuel pump. Mercedes Dealer is guessing and I just need a proper answer. The fuel pump will not operate anymore due to a bad computer. The part number is A2731535679 and the original control unit part number is A2731535079. Any help would be appreciated.

Answer: Yes, this is a very common problem with the S550. The fuel pump is grounded by the ECM ECU and when it fails it will no longer control the fuel pump. The only option is to repair or replace the control unit part number A2731535679. The old part number A2731535079 has been replaced by 2731535679.
