    Hi, i have just bought a 2002 e46 330d tourer. The tailgate warning indicator is showing that the tailgate is open when its not. Because of this, the interior lights in the boot stay on.

    Anyone have any ideas how i can sort this out?

    and its draining your battery?
    sounds like the micro switch on the catch is showing the tailgate as ajar...any issues with the boot not locking at all?
    what i've felt,what i've known
    never shined through in what i've shown.

    Hi mark, the boot locks fine, i have now removed the bulbs in the boot to avoid the battery from draining.

    Have you tried the glass boot opening also, it also will set off the boot open fault. As your a new owner you may not know its there. If you find the wiper, there is a small microswitch under the tab and it unlocks the glass from the rest of the boot opening, if that is not closed properly that will also keep your lights on inside on the touring, otherwise it's as Mark says it's the dodgy microswitch, you might find that it just needs adjusting rather than replacing...good luck.

    The glass opening is fine, it sounds like it could be this micro switch then. Could you explain where this is and what it looks like, as i have no idea what im looking for, and just know i would get ripped off if i take it to a garage.

    Thanks for all the info guys

    The first thing i would suggest is to check that they (Glass and Main) boots are closing properly. Secondly, check that the 'hook's that locate in the locks are firm and secure. Third, would be check the locks for any sign of breakage or obstructions.

    I dont have access to any photo of the locks themselves sadly, this very much looks like unit replacement rather than repair. If the microswitch can be replaced (BMW have quote someone £50!) then you will need some skill at stipping this apart and doing it yourself with something that costs a £2 from RS (more likely the option).

    Well for the main boot lock it would be item 1 below.
    http://www.realoem.com/bmw/showparts...19&hg=41&fg=60

    To find out which one is sending the signal try disconnecting the wiring plug to the rear wiper on the glass boot this should then determine which one it is. As for switches should be operating as NC (Normally closed) then this method should tell you if it's the boot one.

    Failing the above it maybe worth making a visit to a recommended local Indy to look at it.

    Sorry i could not have been of more help.

    Thanks for all the help guys.

    I have now fixed the problem. Being the touring, there are 2 micro switches, one for the rear window and one for the main tailgate.

    To rule things out, i used a screwdriver to push the switch all the way back as if the tailgate was being shut. I then checked the dash and bingo, the warning light had gone out.

    So obviously this meant the tailgate was not pushing the switch all the way in. So all i did was adjust the bracket on the tailgate that pushes the micro switch in when you close the tailgate.

    It worked, no more warning light

    This happens periodically on my saloon, I assume adjusting the micro switch will cure it. cheers

    First i tried adjusting the micro switch, but this made no difference. It was the actual hook that clicks into the micro switch that i had to adjust. Then all was perfect.

    Just thought i would let you know, as it took me ages to get all the trim out of the way to get to the micro switch fixtures, when this ended up being a big waste of time.
