Hi guys,having a problem with the bluetooth in my A4 B8,it was working and now is not,cant figure it.It isn't even looking for a phone,it is the Audi concert stereo with the phone cradle in the armrest,but i've always used the bluetooth connection.The voice activation button on the steering wheel doesn't react either.My local dealer wants 100 euro just to run a diagnostic on it,any help would be great.i checked the fuse in the boot and it ok!!!
