open door warning

disconnected the battery on the car, and reconnected again- no change
tried changing the battery on the remote, no difference.

running out of ideas, so will reluctantly be giving to local mechanic to diagnose.

You could try sitting in the car hold the remote on the Passanger side floor and pressing the buttons again. See if that works.
Do you have a spare key? Try and see if that works or not.

vygec...I've had the exact same problem for some time now and have resorted to just using the key for locking/unlocking (can't afford to bring it to the garage just yet). My fob does work now and again, but its rare enough and it usually only works on drivers door only.
I tried everything mentioned above and checked my ccm and it was bone dry as were the electrical connections.
I'm beginning to suspect a relay under the dash, but not sure which one it is. Anybody know?

I'd be interested to hear how you get on.

Hi Joto,
The fobs can fail if you have a spare key see how that is with the car if you dont and you have Vag-Com or VCDS you can program anotuher key fob as long as the MHZ is the same.
This can be found when you take the Key away from the Fob.

Have 2 fobs, both the same. Changed the batteries in both; disconnected car battery as mentioned earlier, still no joy, same as 'vygec'.
I doubt if both fobs would fail at the same time.
Think I'll try what you said about getting down on the floor and trying it, just to check it's not the aerial.
