[alicksambo]

Am getting a Parking brake malfunction followed by a Gearbox malfunction on my Audi A4 B8.

The car drives well and also shifts gears when this error comes especially after driving and putting the car on park.

I know this seems counter-intuitive, but you might have better luck in the B8 S4 section.

The B8 A4 didn't come with the DTC transmission here in the US, but the S4 did. There are a handful of non-US members that post here, but you'll likely get a lot more input in the S4 section.
