Hi all,

First-time poster! My partner recently picked up a 2002 GTI 1.8T that I've been doing a few bits on, but electrical gremlins have gotten me stumped so I'm asking for your help.

I've recently fitted a new Sony head unit to the car. It works as it should, apart from resetting every time the car is locked/unlocked, meaning she has to mess around re-pairing her phone and whatnot every time she goes anywhere. The ignition and engine can be cycled on and off without affecting it, and I've cleaned off the battery posts and checked all the connections are tight, but that's as far as my limited diagnostic skills have gotten me so far!

The car has the same central locking issues that seem to be the norm for these and the driver's door doesn't work - not sure if there could be a link?

Any help and suggestions are appreciated!
