ECU and faults issues

Post by Plumberstu » Mon Jun 26, 2017 5:03 pm

Hi I'm new here and new to the RS4.
I'm after some advice, I've recently purchased an RS4 B7 that was stolen and recovered. It need some work so I brought it as a project car.

The issue I'm having is it is misfiring on the nearside the engine management light is on, it's currently at my local Audi VW specialist, the have plunged it into vag-com but there is no fault codes stored.

They suspect that the ECU may have been corrupted by whoever stole it.

Does anybody know of a way to reset or reflash the software on the ECU or if buying a second hand ECU would work.

Cheers for any help
