Hello just incase someone has experienced the same issue and can give some help.
Last week after starting the car 2017 a4 b9 allroad as i was setting off the horn was tooting and sounding for 2-3 seconds at a time, i pulled over turned the car off restarted the engine set off no problems, it was ok for a week then at 4am was sounding off for 5mins 2 or 3 times in 40mins, this is the horn sounding not the alarm siren i pulled the fuse for the horn and havent locked it again as yet.
Vcds said alarm system error missing signal has anyone else had this issue? Thanks dave
