I have recently acquired a used Audi A4 cabriolet and am very pleased with it. The only bug-bear is that there are a couple of lines missing on the led display on the head unit of the Symphony II sound system. The local Audi dealer has offered me a re-conditioned one for £350; I'm tempted but it seems a lot to pay for a few red dots!
Does anyone know if the displays are repairable and, if so, how I may go about getting it done?
