    Wiring diagrams are in a separate document called electrical guide. In the stickies somewhere too I think.

    Not all that clear will have to take the J-Gate apart, Not sure if it is the "Not In Park" switch on page 77 of 200 or is my box a ZF which is somewhat different, it is a bit of a grey area. It is behaving at the moment.

    There's a micro switch at the top of the brake pedal which if malfunctioning will not allow the gear shift to come out of park. There's also a video on youtube showing how to get around this problem temporarily till you can get a new switch. Apologies if this has been covered in the above posts eg interlock solenoid.

    No Probs with the Gear lever, Good to know about the microswitch.

    series 2 cars and onwards have ZF boxes. 2002.5+
    If your car is making the rapid beeping sound when you try to remove the key, it is because it thinks the gearbox is not in park. I don't believe there is another reason for that noise coupled with the key removal.

    Spot on ! BTW what does 2002.5+ mean? Mine is from 03/2005. Moving the lever slightly in the P position turns the beeping on and off allowing removal of the key.
    While beeping the key cannot be removed. So what is sensing the lever in the park position. I saw on the 5 speed box that there is a "Not in Park Switch" but cannot see what it is on the ZF. It feels local ie on the Jgate assembly, because the lever position is very sensitive when this problem occurs. Is it a slider on a pcb, a microswitch, Opto or Hall effect sensor?

    2002.5 just means half way through 2002. Your 2005 car will be a ZF box 6 speed.
    I don't exactly know how it senses park or not in park but I though it was something to do with the gearbox interlock solenoid. There must be a micro switch that senses the park position, however, there is only one switch listed as parts.

    There was a big model revision with design changes halfway through the year incl. suspension & bodywork & these are referred to as 2002.5 cars.

    From the sensitivity of the lever I would guess it is local to the lever. If I can get my A/C sorted I won't mind sitting in it and having a close look under the console.
    I've got an endoscope which I got to look at merc M271 timing gear teeth, might be useful here to save a bit of effort too. Need to check the circuit diagrams again.
