Flashing the head control unit
 

Hi all!
I have an issue with the HEAD CONTROL UNIT dying off. It`s happened once before - and now again.

Anyways - I bought one from a car dismantler and it turned out they sent me a unit that originates from an A4...:(

The part numbers are the same: 4E0035729A, but the software is different. so to my question:

Is it possible to load the software from the 8?

In that case how, and where to start?

Best regards
Pelle
