    Mine has done it a couple of times too.
    orly? How come it affects all sorts of weird things like rear suspension, remote locking and parking sensors?

    I think the switch works as 3 separate ones, and if one or two of the other switches don't flick, the control units end up rerouting power from different wires and can struggle with voltage.

    Different car, but similar switch, and you can see the odd collection of problems. Fault codes should reflect power problems with "terminal R" I think

    well that guy said it was cruise control and the navigation/radio would turn on and off. can it effect other stuff? and before the whole thing happened for me, things used to turn back to normal while driving. at least my cruise control works perfectly (did yesterday at least) and the navi/radio works fine too except all dash died. i was going to do diagnostic yesterday but the guy never answered the phone to meet him. so cant do anything till next week.

    I've had it where the car cuts out for a second then restarts, the interior lights coming on, and ABS lights coming on, so it turns up as odd electrical problems.

    The switch isn't that cheap, so best to get codes read first, and maybe check the battery leads are tight before buying anything.

    after going over the car my bro found that there was damp in the heating system for the car (you know the deisel powered one that produces heat before the engine gets hot - i didnt know it even had this lol) so alls working for now after it's dried out... he's sealed it up so we'll see if this happens again.

    Auxillary heater = "webasto"

    If it is anything like the others I have seen, it will have 2 faults for power and K-line communications stored.
    I'm not sure what the fix is, most likely the heater unit part itself.

    i have unplugged the power from it before winter started had no problems till 2 weeks ago. i suppose its an ignition switch or the ZKE most likely for me. too bad i'm having problems finding someone who can read codes, because the one i suppose to be going to said i need to leave car for longer period of time and i cannot do that. so ill have to wait for my own cable for code reading to arrive from UK
