The correct steering wheel with paddles for my car is 8T0 419 091 B WUL.
My airbag is 8K0 880 201 E 6PS.
My airbag cable harness is 8K0 971 589 A.
My original steering wheel was 8T0 419 091 A WUL.
The steering wheel that did not fit my car was 8R0 419 091 G WUL. Normally this is not an A4 part, but it seems some cars came fitted with this one, but mine did not, so I had to resell it and buy the correct one.
My car did not accept the coding for the gearbox, it only accepted the one for the steering wheel, but the paddles are still working perfect.
