My 1997 355 had a convertible top that wouldn’t go down. Replaced the hydraulic hoses, both seat potentiometers, and the elastic bands. Got the top working and “taught” the computer the seat positions. Worked exactly twice. Now the dealer has it and can’t figure out why after several up and downs, the computer seems to forget the seat positions. Anybody else ever heard of this? BTW the battery is brand new and everything else works fine.
