Central locking issue

[Nottmman76]

Hi I have a 2006 A6 Avant that has a Central locking issue. All the doors lock except for the passenger front which can still be opened from the outside when the rest of the door are locked. I can hear the motor working inside the door when I lock and unlock the doors but I can still open the door for the outside. Any clues?

I'm having this on my rear passenger door, at times it works from outside and other times it doesn't. When I scanned with VCDS I was getting this error :-

As the sunny days are coming back plan on sorting the issue and will hopefully take pics and do write up. I know there are members who've fixed this or had same issue.

Hi ya Dan ,

Yes indeed matey , I recall there was a thread about this topic which I think you and B5NUT were sharing your experiences.

How much was the part BTW?

[dan2485]

A year ago i got a passenger door lock for around £114 form TPS new. This was on a friends 2006 A6 Avant.

A rear lock should be cheaper.

Cheers! as you've seen this part and I haven't do you think there is something serviceable on it to make it come back to life? only ask as a) mine seems to work at times b) trying to keep costs down as recently wife had a low speed accident (she's at fault) and I need to get work done or do myself on front end.

[dan2485]

There is nothing serviceable in it, I still have it in a tool box at work and i will post up a few pictures tomorrow.

The micro switches are potted so no real way to replace them and the lock is not easy to put back together.

For the price of a used or new not worth the effort in trying to repair, i thought that it could be a simple switch change.

This chap repaired his lock, may be of interest to others - A6 (A3, A8) doors not unlocking. - AudiWorld Forums

Roy! Cheers for that mate! as mine is intermittent I think I will have a meddle with it first! if I didn't I don't think I'd qualify as a "meddling owner" ...

I have a similar problem with my drivers front.

I've noticed in temps above 10 degrees it doesn't happen, for now am happy to open the rear drivers side and open rather than spend £££'s fixing....hopefully for Summer it will be trouble free
