Sounds like a problem with the door latch mech to me. If you have it scanned for faults, it should show the problem. If the door latches are the same as the golfs, the micro switches become sticky. Not sure how you overcome it with out a new mech

Sounds like the switch thats in the door latch mechanism... common problem normally requiring the latch to be replaced as its integral or if you are feeling brave then there are guides on the web to swap the micro switch out...

Reason it locks is the alarm is designed to rearm/lock doors if you unlock the doors but don't open them... this happens a lot when I open the boot on mine as the switch sometimes doesn't work on that too..

could probably change the latch, how much should i be paying? is it best buyin new from the main dealers or 2nd hand? last time i went to dealer got stung to the tune of approx £600 for one alloy wheel and tyre!!!

thankyou

Not cheap IIRC... best bet is to give your local dealer a call to baseline it... you may pick one up on ebay (never looked tbh) but don't be tempted to buy second hand... its that common that they will all do it eventually...

Like I said, there are a few guides kicking about on the web as I have looked into this myself to swap the microswitch out with one from Maplins... tricky to do but a cheaper alternative..

Here you go...
You CAN replace the 'Door Open' micro-switch in the door latch. - AudiWorld Forums

The Audi TT Forum :: View topic - TT Lock Switch -opinions on creating a fix. Got 1 option

Give you something to think about... the second link you will need to read through a bit

Have you tried unlocking the car and then opening one of the other doors to see if it still locks itself?
