    Electrical faults, windows and central locking. :(

    Hi all, I've got a bit of an issue with my electric windows and central locks, so the problems are, drivers door window switches not working(passenger switch working fine) when using the key to manually unlock the door it only unlocks the drivers door then when the ignition is switched on all the doors unlock, also when the key is inserted into the door manually and held over to the lock or unlock positions the windows do not open. And my remote central locking is not working on the fob.
    So what I've tried to resolve the issues are,
    ive had the door card off and checked the wiring loom in the door, I did have a few breaks they was re soldered back together still same faults occurred, I've checked the continuity through the loom all the way from inside the drivers foot well up to the window motor and all is fine, I've had the passenger seat out and the carpet up, no water or moisture is present and I cannot see any green on any of the plugs or in the convenience control module, I've checked my feeds and earths and can signals up to the motor and all are present, I've also had vcas connected up it would not connect to the door control module and threw up a key 1 fault. I've changed the window motor in the drivers door and still not working. I've ordered a new switch to rule that out but is there anything else it could be? Any held but be great thanks

    check the pins in the connector they may be all green and gummed up mine was that bad some of the pins broke off!!

    you might get enough to show continuity with a multi meter but it may not be able to carry the loads required to operate the rest

    I would connect it all up then check the main power cable to see if you are getting power to the door controller

    yeah it should be close to what the battery is reading

    I would do a resistance test too on the door loom while you have easy access to it

    It's really starting to get on my nerves now, I'm a Hgv mechanic and its baffled me, I took it to my local garage and they diagnosed it at the door control unit/window motor so I've just brought one at 200 quid and it's not fixed the fault, I've herd the switches can fill with water if the window is left open so I'm goin to try that next. If that don't work then it's time for a auto electrician I think unless anyone else on here has any info.

    Put it all back together now, when locking the car manually with the key the hazards intermittently work and also the interior light works as it should. These are all checks I've carried out by looking at other people's threads

    All sorted now. I put a new window switch in and it's working, stripped the old switch down and the circuit board had lots of corrosion on the solder joints.

    The central locking is working manually on the key, I did another full scan on vag com and I have a key 1 fault, spoke to a mate of mine and apparently it needs reprogramming I only have 1 key for the car so I'm going to get another key and have them both done.

    have you tried inserting the key in the ignition and switching the ignition on press lock and unlock on the fob then turn it off?

    this usually solves most remote problems

    00955 key 1 is the fault it came up with.tryed a few different things to try getting it working again, new battery, disconnecting the car battery, and a few different button combos with the key in the ignition and in the drivers door lock

    00955 - Ross-Tech Wiki

    looks like it need adapting to the car again as you say

    this can easily be done in VCDS the dealers will charge the earth!!

    check the VCDS map to see if there is a member nearby I have VCDS and I'm in Hull yorkshire if that helps at all
