Dear everyone, Working on a vc upgrade on my 2014 a3 8v. VC running ok. (2 problems, 1 cannot change it to TDI, 2 trailer gives error) Today i wanted to change the steeringwheel to a a3 8v FL with the VC View button. The lights work. Buttons do not react. Whats wrong? Tried old steeringwheel and mfsw works... New steeringwheel has 4 wires, 3 black 1 purple... airbag loom has 3 wires (bought as a set from a3 8v) Even tried another View wheel, (same pinout) nothing.. Should be plug n play?
