    Hey all,My 2005 sport back 1.9 TDI is acting weird! I've had a scan for similar problems but no one seem to have my exact symptoms. - driver side door fails to lock/unlock via key fob but locks fine with key. All other doors lock fine with key fob. When lock with key and use fob hazards work but if I don't lock drivers door manually no lights flash.- driver side wing mirror doesn't work at all but passenger side works fine.- driver window does go up and down but a bit juddery not like passenger window which again works fine (driver window goes down by itself if held but doesn't go up).Any ideas guys? I want to replace the loom from pillar to door but if it was that, everything would be dead? Any help would be really appreciated as its been ongoing for a while now.Cheers Gussy

    Could be an intermittent connection though in the rubber boot.

    Symptoms are constant not intermittent though? Do you mean the rubber boot between door and pillar?

    Ahh right yeah but seeing as it's only the one door being effected i'd try a circuit test from both sides and move the door to as it may/may not connect on door movement.

    it will rule out a broken wire for sure.To get to the core of a wire use a pin to pierce the covering then put the tester on that.

    If the door locks are made of cheese like the range before them (ie golfs/leons) could well be the door lock module.

    Yeah autolatry that's what's so weird. I expected the faults to be apparent on both side as I presumed they are on the same circuit?

    Just a quick update. I took apart the loom to find wires twisted and snapped!!! Have no idea how it happened but I'm going to be taking it out and inline splicing 2 of them. Hoping that sorts the issues! See pic

    Missed your post, and was about to say it's definitely the wires broken in the door loom! (you might find an old post of mine a few months ago with the same problem). Mine was exactly the same, door lock and mirror not working. And they had broken in the same way, they look almost as if they have been cut!

    There is too much wire length between the door and the body so it obviously gets trapped and bent too much when it's closed and they break. I just soldered them back together and everythings back working ok now.

    Also, has any one got a top tip to get that connector off?

    The clip for the connector on the body is on the "back", just reach round with a finger and it's in the middle, press it in and waggle the connector out. Ignore the purple bit, it's nothing to do with the clip.

    On my car I removed the boot completely so I could solder the wires back together. Now one issues with this is the boot on the door appears to clip round a loose piece of plastic inside the door itself so looks like it needs the door trim removing to put it back on properly (not got round to doing this yet!). To remove the boot completely I slid it over the connector once it's disconnected, it can be done when warming it up and using washing liquid on the connector so it slides through.

    Update.

    I took boot away from pillar and door and spliced an 18awg bit of wire in. Wrapped it up and fitted boot back together. All is well now!

    Tips for anyone in future...if you take the boot away from the door the best thing to do in order to get it back on properly (avoiding water ingress) is to take door card off and remove speaker to get behind the plastic clip. Push it out from inside, fit boot over said plastic clip and push it back in.

    Cheers for help guys
