I recently swapped the standard steering wheel for a FBMFSW from a TT with DSG paddles. Everything seemed fine - the DSG paddles work and light up - but when I try the horn, not a peep. The horn worked before with my old steering wheel. I've checked the fuse, and checked all the plugs were attached correctly.
I've taken the airbag off again, to look at the wiring. There are three spade connectors on the back of the airbag, but only two are connected up. Is that right? I'll try put a picture here, but if that doesn't work, I'll try describe it.
Holding the airbag so the green connector is on the left and the orange connector is on the right, there is one spade connector around the 12 o'clock position, and another around the 7 o'clock position. These are both connected up. But there is a third, unused connector around the 1 o'clock position. What is this for? There doesn't seem to be an unused wire to attach to it.
I can't see any other stray wires sprouting from the steering column or slip ring. Nothing is mentioned in the how-to guides I've found. Those all suggest it's a pretty straight-forward plug n play, straight swap. Mine's an 05 five door Sportback. My old wheel was the shield-shaped airbag, not a multi-function one, but it was also a dual airbag with green and orange connectors. The TT one has a round airbag if that makes any difference?
Any ideas anyone?
