    Door lock microswitch, try manually pushing the lock mechanism up & release with handle, some wd40 may help to clear some gunge mate, well known issue, if fails try removing lock, opening it up & checking microswitch position & clean, I have done this before.

    As far as I saw the boards were soldered very well, so dont think this is it, but certainly test full functionality whilst its of & its just 2 bolts on the side of the door mate where it locks, it has a plastic lug straight piece that locks into a hole in the lock mechanism, this is the pita piece that pisses you of, but not impossible to refit, once done then you'll remember how to do each time, but make sure you test full lock functionality when refitted as in door handle, exterior lock with key etc before putting all back.

    For me your microswitch has got either stuck from gunge or its buggered, I do have a drivers lock for sale if need be.

    Then would work on yours as the locks of a 54 aswell.

    Yeah its possibly dislodged something or the mechanics have slightly moved out of alignment, just remove lock & all should be revealed.

    thanks mate, will look into it in the weekend,me pretty sure its the mechanics cause when i have the door open and i push the lock to lock and release it with the handle the lock dont seems to release fully,

    oh another problem me just noticed is that if i have the headlights on and i off them (to sidelights) they take around 5secs to go off, do you know what that can be?

    You could try checking measuring blocks in 09 with vagcom.

    Switch I have is 8P2941531L, your part number is on a sticky label on the switch.
