    Hi Remote locking just stopped working,neaver had any issues before (help and ideas please)

    1. Have tried spare key and recoding key
    2. central locking works fine with the key
    3. radio works fine gets all stations
    4 have checked voltage to BM5 MODULE (behind glove box )PIN 49 as suggested here BMW General Module 5 (GMV, ZKE V)
    but no voltage
    5. So looking to find Aplifier module

    Questions

    Is It definately in the rear spioler ? then I am led to belive you have to open the rear window ?
    to undo the bolts

    If so how do I open the rear window as the manual button under the wiper has neaver worked
    and cant open it with the key fob as the remote locking is not working,is there another way to open the window

    Also does anyone know a good way to work through a faulting process
    for the remote locking so I can be sure which bit is at fault ?

    Thanks

    Oh me me me! I know the answer!

    I had a customer with a similar fault and it turned out the receiver, which is indeed under the spoiler cover, was faulty. I fixed it for him and remote locking was restored. As you say the GM5 is not faulty as it does work with the key in the door and centre console button.

    You need to locate the relay for the glass hatch, which is located next to the GM5 module. Also check Fuse 58 7.5A is okay.

    Find the relay, which has moved during the E46 production, but is always beside the GM5, not the bank of relays above the unit.
    It will have three wires:

    white/blue (goes to GM5, middle connector pin 31)
    Red/Brown (+12v from F58)
    Brown/Red (drive to the rear latch)

    It is probably easiest to disconnect the GM5. Reconnect the battery and locate middle loom connector of the GM5, (biggest connector in terms of number of pins).

    Pulse pin 31 to ground.

    This should cause the glass hatch to pop open.

    At the glass hatch, remove the black plastic trim cover from inside.
    Locate and remove the four bolts holding the spoiler on.
    Under the spoiler is the receiver module.

    Contact me if you are unsure or require more guidance.

    PROBLEM NOW FIXED

    Thanks mainly Due to Colin (what a great bloke)

    1. Released the rear window by touching earth to white/blue on relay (as described above) just scrapped off enough plastic insulation on wire to show copper cable
    2. Removed spioler to see black amplifier module (about the size of an old cassete)remove left hand side black plug on module it has three wires
    blue/white (on the right) should 5 volts, white (in the middle) only had 12 volts when radio was on, red/with thin purply blue (left) should have 12 volts
    mine did not
    3. Found the red/with thin purply blue wire in the loom in the far right compartment at the base of load area (where battery is)
    scrapped off a bit off insulation and measured voltage,getting a good 12 volts,therefore must be a break in the loom between here and top of window
    4. pulled red/with thin purply blue wire where it goes into the long rubber bendy tube between top of window and body and it came out (must where break is)
    removed bendy rubber tube at top of roof pulled same wire and out it came
    5. Soldered in new piece of wire at both ends,first feeding it through rubber tube (what a game)
    6. Bingo 12 volts at black plug, Remote locking now working again


    All info from Colin,cant thank him enough, would definately trust his business
