My 2004 A3 TDI threw up a fault code on my scanner recently:
01134 - Alarm Horn (H12) - static - no define
Tonight I locked the car with the key fob, then unlocked the drivers door with the key and opened it. The indicators flashed but no alarm horn. I am guessing it needs a new alarm horn.
I have done a search on here and people have sorted theirs out before, so I think I can probably do the job myself.
However, short of some used items on ebay, I cant find any new alarm horns when doing a google search.
Anyone got any suggestions?
