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

• 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.

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!
• ECU injectors/coils test good and much more!  

• Disconnect the negative terminal of the battery. Make sure the battery connector is not touching the battery post.
• Disconnect and remove the module to be replaced.
• Install and connect the replacement module.
• Connect the negative terminal of the battery.
• Ecu will now need programming or coding to your vehicle. 

• Pins perfect, none are broken or bent
• NOTE: The mounting prongs are not included but you can swap them from your original ecu on to this unit easily. Also note the case is slightly dinged which did not effect the circuit board and one mounting point is missing but we belive the other 3 points will hold this unit firmly in place. Please review the pictures prior to purchase.
