590337 Location. France. My Photo Gallery: 0. Audi A4 B8 S line steering wheel swap, horn not working. Guest-only advertisement. Register or Log In now! Hello,
Directswap. Horn is pins 1 and 2. Pressing the horn (pressing the airbag against the wheel frame) closes the circuit between pins 1 and 2. Set the airbag into the wheel (dismounted) and put a meter or test light on pins 1 and 2 of the yellow plug sticking through the opening in the back of the wheel. Thechime drives me crazy sometimes when I just want to keep my door open for a few seconds and lights or the engine is still running or something. I would sort of miss the turn signal sound but I could live without that. Current: 2013 A4 TFSI | Past: 2010 A4. CAEB Longitudinal EA888 Gen2 155kW. MPG 24city 31hwy. jemi.
