Messed up locks & remote

[David Fay]

2007 A6 3.2 -- it started with passenger door not unlocking from the master inside switch and now when using the remote only the rear doors lock (there have been a few additional variations of this problem since this started). Any info is appreciated. Thank you

Get it scanned with vcds and check for any errors.
Door can be enabled/disabled in mmi settings. It may be obvious but have you tried there?

Not sure if you have the same problem but sometimes the micro switches in the locks fail. You'll need to get the car scanned to be sure but take a look here:

Right, someone just had similar issue here.

Can you open the same door from inside?

There was a comment on the recent thread about a part needed to be replaced and it should solve the problem.
Check some recent threads about passenger door problem one member had just now.
I might have thrown in some thoughts also.

If doors cannot be opened from both sides, it would be the lock, most probably.
