Have started sifting through all the threads about these, but thought I'd throw a question out anyway! Bit of back ground first, when I bought my Disco (a '94 300tdi ES with air bags) the horn worked fine, now tho its stopped working and while attempting to press the horn switch on the wheel (which didn't work) the SRS warning came on and now stays on when driving! I asked about it at the time and someone suggested the Rotary Coupler....my question is, can these be repaired like so many other electrical items on the Disco, or does it have to be replaced?
