Attn: Anyone who has/have had problem with door lock sensors
i.e. the dash display shows the doors as being open when they're not.
this is real problem on the A3. the problem (as you may/may not know) is that the micro switches in the door latch-unit fail prematurely. I've head enough of paying out £40 a time to solve the problem.
The switch is, I think, the same on the A6 and I have traced who makes the switches and have a contact email - I have spoken to the UK branch of the company - Cherry, and they said the more people that contact them the more they will listen and something will get done.
If you have this problem and want to do something please say so now!
