Product Description

Part Number

Please match the following 0 261 209 294. We recommend matching the following but believe your MB shop can update this: A 272 153 51 91

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 2006-2009 E350 CLK350 C350 models with an exact part number match. Programming is a must.
