Hello there, first post here.
Ive had my A4 avant tdi sport now for about 3 months, loving it, apart from the problem im getting with the stereo / speakers.
Its mainly the passenger side front speaker, which keeps going on & off.
I am about to strip the door card off to check the wiring - but I suspect it may be something else, as some of the other speakers occasionally crackle & go on / off. I have removed the head unit to check if anything is loose there, but it all looks ok.
Any advice greatly appreciated.
