    Well I took it in and they suspect that the module that controls the windows, seats, mirrirs etc. has gone but dont want to commit to replacing it yet.

    They read the fault codes and there was loads but as we dont know when they where last cleared the garage has cleared the codes and I'm going to drive it for a week and take it back to see what new codes come up.

    Well that's a start, make sure you try to operate everything you possibly can in that week

    Did you take a note of what codes had been stored?

    Bit of an update.

    It's all going to pot now.

    List of stuff that doesnt work as of today.

    1. Passenger Mirror
    2. Passenger windows from drivers controls.
    3. Seat, wheel and mirror memory.
    4. Front doors central locking.
    5. Stereo / Satnav (comes on for about a minute with no display.)
    6. Dashboard indicator lights and audible notification. (yes I do use them, lol )
    7. Parking sensors dont come on automaticaly.
    8. Heater Blower (still as when I bought the car)
    9. Auxillary fan. (as above)
    10. Passenger mirror dipping when reversing.

    Going to have to get it booked into an auto electricians before the whole lot packs up on me.

    Passenger mirror is supposed to dip when revering I think It's so that you can see the kerb so you don't make a mess of your wheels.

    Perhaps another member will confirm this, i'm sure other cars do it.

    If you've got a multimeter then check the charge rate at the battery when the car is running

    Cheers Ronnie I'll give that a check tonight.

    The self levelling suspension packed up this morning too.

    Unless it is a charging issue I'm thinking either the main control module is slowly dieing or theres a serious short behind the dash somewhere.

    I'm going to have to pull it off the road before it goes up in smoke or something as severe. It's a good job Ive not managed to sell the Passat yet.

    Bit of an update. I've found a shorted wire under the dash. It has melted all the insulation of itself and some of it's neighbours.

    I've started stripping the loom back and seperating the wires which has resulted in some systems coming back on. Other stuff works ok depending on which position i wiggle the loom.

    I still need to strip it back further but the throttle pedal is stopping me pulling the carpet back and I cant work out how to remove it.

    Anyone know how to get an E39 throttle pedal out?

    Ouch, not good! Any idea why it's been hacked into before?

    For the pedal you need to use a screwdriver pushed down the side of the pedal base/floor and push the plastic tags back, see here for a rough picture http://www.realoem.com/bmw/showparts...68&hg=35&fg=10

    Thanks for the link Ronnie. I keep forgeting about realoem.

    Anyhow this is the diagram for my pedal as it's fly by wire.

    http://www.realoem.com/bmw/showparts...49&hg=35&fg=20

    Which helps a bit although I'm not sure how to get the cover off that covers the bolt on it. I'll have a go at it tommorow.

    Looks like it's bolted in from the side and then slides off?
