Audi A4 B9 ECU Short Circuit


Registered User
Hi Guys,

I'm new to the group. I've managed to diagnose that my ECU is blowing the fuse so my car in currently undriveable.

I'm looking to replace the ECU with a refrubished part on eBay.

Are any of you aware if i need to get the ECU recoded with my vehicles VIN number before it will work? If so, do you know any garages apart from Audi main dealer who could do this?

Thanks for your help,

It will need matching yes & maybe best to goto Audi for that, if they will do with a used ECU.
