Hello,
I am the owner of an Audi A4 Avant B7 2.0 TDI, manufactured in 2008, and I had a detachable tow hitch from Westfalia with a Jaeger electrical kit installed last week.
Can anyone help me with coding the ECU?
I have already re-coded the onboard electrical system control unit: now the trailer hitch is obviously recognized, because the fog light on the car is no longer off when a trailer is attached. Before the coding, the fog light on the trailer AND the car was off. But unfortunately, my rear parking brake is still not being deactivated

. It seems like another control unit needs to be reprogrammed!?
I would be grateful if someone could offer me some advice!
Best regards,
universe
