Hello. I have the following problem: With my Audi 80 Cabrio MJ 95 the electrical unlocking is defective via the switch on the B-pillar. It can be opened manually of course. To the info-the cover is manual, not hydraulic. With a familiar Audi compartment I have already installed and tried another cover control unit – no change, it does not work. Maybe someone of you has a useful tip, so that I might have expensive hours of troubleshooting in the Audi workshop can save money. Thank you, greet fire guns
