Have mot shortly and my horn doesnt work :(
The old slip ring when connected used to sound the horn when i turned the steering wheel but not when i pressed the horn, now that i have another slip ring i does neither.
I have triple checked the part numbers, and spoken to bmw directly and have assured me that the part they supplied is correct. Is there anything else i should be aware of?? and/or any other way of getting aorund this??
