    Door lock, window, mirror issue

    I own an 07 Golf Mk5 right hand drive that has door, window and mirror issues at the moment.

    The left side doors, passenger and rear passenger doors will not unlock or open in any way. The passenger side mirror can not be adjusted and the turn indicator light on that mirror does not light. The windows cannot be lowered either.

    The fob works on the drivers side as does the side mirror adjustment and window adjustment.

    Is this an electrics issue somewhere? I suspected the door loom but is this unusual to be happening on both doors?


    Any help greatly appreciated.

    You need to get your motor scanned (preferably with VAG-COM\VCDS) for any error codes logged in the ecu and post them, that will save a lot of guessing. Investigate components check.

    I had this last year on a 2007 R32 4 door. A few weeks earlier our bodyshop had fitted a new left rear door skin and everything was OK, it even went through an MOT test. We then had it back to do some suspension work after which it needed to go back to the body shop as we had found some more work that needed doing. I was backing out of the bay and noticed the left mirror was folded back so I tried to open the window to lean out and flick it forwards, but the window would not work. I got out and found the door would not open, the locking system did nothing, the mirror and its indicator did not work and to top it all, the rear door was also dead. I was bemused to say the least and a fault code scan showed

    My initial suspicion was that the left rear door control unit or lock unit were at fault or the wiring, as it is completely operated by a LIN (Local Interconnect Network) signal provided by the front door controller which is combined with the window motor.

    I accessed the left rear door wiring at the A pillar kick plate with the sill trim removed (which was a fun job with the doors shut) and accessed the four wires that go to the rear door, thick red/yellow which is the main power live from fuse 26, thick brown for earth, thin red/black from fuse 24 which is live again and the thin purple/white from the passengers door controller which carriers the Lin data signal which controls ALL the doors functions. I could not see anything wrong, I had a LIN signal and the wire had perfect continuity back to the door, anyway, it was the front door I was really worried about. The front left door controller has the LIN wire for the rear door, two fused permanent live power feeds from fuse 12 and 23 and two CAN (Controller Area Network) wires which carry the data from the central convenience system.

    I was beginning to suspect the convenience unit but to get this out you have to remove the glovebox and to remove the glovebox, you need the door open! I decided to hot wire the front door controller signal to the lock by getting at the wires through the hole left by the door handle but try as I might I could not trick the motor into working.

    Next a friend of mine help me to remove the passenger’s seat and then he managed to release the door card without damage just far enough away so that I could drill out the six speaker unit rivets and remove the speaker. Whilst he lay on his back he got his hand up inside the door and was able to disconnect the plug to the lock unit whilst I hot wire a new long lead plug from the driver’s door controller, so both door cards off! He was then just able to plug the extension harness in, I pressed the remote and the door opened.

    As a test we then plugged the normal feed in and shut the door and operated the remote it, it was still dead so we hot-wired it again. I decided to try a new door controller and this made no difference. Now I could get the inconvenience unit out and fit and code in a new one which I did and it worked, the rear door opened and all the doors functions came back so I built it all back up and it was fine apart from I had forgot to match the remote to the new convenience unit. I tried to code it is and it would not have it no matter what I did, VCDS or VAS PC. In desperation I put the old one back in to make sure the remotes (I had both) were not the trouble and they worked but so did the doors and windows etc, I was stunned. I built it back up and all is well after a year as it is here again for annual MOT and some moods. No, I can’t explain it…

    Bit of a thread revival... but thatís interesting about basically removing and reinstalling the ccm and it working, Iíll give this a try When I get chance before attempting the what seems like a pain experience of replacing it

    And to this day the fault has not returned.... I fitted a new convenience unit to a Passat a few weeks back and this chnaged the ABS coding to a different value and something else, I can't remember what, and this made the car pull to the left and this is correct, WHY?
