Product Description

Part Number

Please match the following 0 261 209 402. We recommend matching the following but believe your MB shop can update this: A 272 153 05 92

Fitment/Interchange

  • You must match your part number exactly as seen above. If any numbers are off compared to your original it will not work properly.
  • Ecu will require programming or coding to your vehicle or vehicle's security system and is not plug and play. You will need to take this to your local BMW/Mercedes/VW "IMPORT SHOP" for programming. Your dealer will more than likely refuse to perform the programming or say it can't be done. 
  • Ecu will fit 2006-2010 C350 CLK350 W211 models with an exact part number match. Programming is a must.

Tech Notes

      ECU has been tested with our state of the art vehicle simulator which tests over 25 circuits of the ECU! Some of those are listed below:
    • Reference Voltage Good!
    • ECU powered up and has communication!
    • ECU fuel pump/main relay test good!
    • The problem areas on the PCB that cause a no crank with the cooling fan running have been tested good or repaired.
    • ECU injectors/coils circuits test good
