Upgrade to Comfort Lock System: Possible?

Hello again!

Can I retrofit my 1992 Passat wagon with central locking so that the windows and sunroof automatically open or close when I hold down the key fob button?
If so, what would I need to get for that?

Is this a complex operation or just a matter of plugging in relays/cables?


Thank you very much.

Hello,

This is a somewhat larger undertaking.

- other central HVAC control unit.
- Additional body control modules (BCMs) in the doors or new window lift motors with integrated electronics.
- In addition, three microswitches on the cylinder lock, possibly with a different type of cylinder lock.
