I have done a search and found a lot of threads on this, but couldn't find exactly the issue that I have.

For a while now, when I unlock the car from the remote key fob, the drivers door doesn't open. When I get in the car, the drivers mirror also doesn't work on the electric adjustment. After a few miles however, this seemed to stop happening and the car was happy to lock and unlock and adjust it's mirrors just fine. But now, for the last couple of weeks, the drivers door doesn't open from the remote at all! This means that i cannot adjust the mirror electrically either!

I am going to scan it with VCDS later and see what it says. But does anyone have any thoughts? Could this be related to a flat-ish battery (hence it used to stop when the car had been driven and battery topped up a little)?? Or is this the usual door control unit failure? if so, how do i fix it?

Any help would be greatly appreciated.

Forgot to say, when I put the key in the door, everything unlocks perfectly. Although still can't adjust the drivers side mirror and the anti-hijack locks don't work.

Hello,

I had this on my car and lived with it for about 2 years. It was intermittent at first and then finally the lock and the door mirror stopped working. It took a very good auto electrician to find the cause and it was one of the connections in the door loom. it rurned out to be one of the pins in the connector had corroded internally and to look at it was fine. Luckily I had bought a second hand door and stripped it of everything, so I had a loom. I also had the door motor and the plastic box that attaches to it, so when they fitted a the loom and the box it all worked perfectly.

Scanning the car merely showed that the mirror and lock didn't work, but I knew that anyway! I'm not saying that this is the cause of your problem, but it might point you in the right direction.

If I can find the old loom, I'll see which pin it was and let you know the colour.

edit : I've just looked and it was the yellow and red wire in the middle row of the connector block, the nearest the clip. Hope this helps.

Here's a photo of the connector in the door I'm referring to. It's not my car, but it's the same place. Water had got in and filled the plastic box. Then that had ruined the pins in the block.
