Hello expert, I can buy from an acquaintance whose coupé (EZ 09/2003, 82 hp, manual circuit). Only known problem is that after a few seconds the doors will unlock themselves again, if you have locked up before. Perhaps some microswitch/sensor/actuator is broken at a lock. Can it be easily found and repaired by the (technically experienced) user or will it be an expensive workshop”fun”? Sometimes there are so’n typical “standard errors” in technical things, the connoisseur already from afar by the symptoms…. Thanks for your opinions!
