- 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. There are also clone services available online or companies that can virginize the ecu for you but you'll need to do some research on those two options.
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. See below for install notes.
