Hi all, I know this subject has been covered,appologies. I have 2007 A3 sportsback tfsi. The usual thing, were working, get the long beep then nothing. I can not hear any buzzing or feel any vibration from any of the sensors. My question is, is there a central unit controlling all the sensors? and can this fail or is it normally just one or two sensors? I have seen something about a unit in the rear ,side panel in the boot , can this be easily changed? I have tried to find a thread that covers this but most seem to concentrate on a particular sensor being faulty.
Many thanks in advance and I hope this is the right way to do it as total neewbie to using forums.
