    Turns out, the part in the photo above was for the auto release on the boot cover which is now also broken.

    I've not been able to find anything on the wiring to the aerial which tells me the fault itself is quite close to the aerial itself.

    For the purple connector, are the pins still intact?

    For the antenna issues, do you own a multimeter? What did you find when you checked in the area around the rubber bungs?

    Unfortunatly I do not own a multimeter Joylove - up until today I didn't even own a Torx screwdriver!
    I traced some cables from the fuse box up the bootlining and into interior roof lining - this is a group of about 12 wires fastened together in some type of adhesive type sheeth. All these wires appear to be intact and complete for as far as I can trace them.

    As for the purple connector - the pins have broken inside the unit.

    I phoned BMW customer services today too, they basically said its not on the AUC warranty as its electrics and as its pre-existing I'd have to deal direct with the dealer - pretty much as expected.

    There is a permanent power there at the FM amp for the alarm receiver.

    If the pins were ripped off you may need to replace them. You want 1.0-2.5mm MQS pins. They can be crushed into place with a pair of needle nose pliers.
    Checked supply to aerial diversity. NO supply found and found harness broken on tail gate. Need to replace wiring.
    http://www.bmw-planet.com/diagrams/r...0e61/index.htm You will need Java and Adobe's SVG viewer. Search for N8a. The diagrams are hyperlinked and you can keep searching for that term until you find the photo and wiring diargram.
    Self-diagnosis of aerial diversity

    The aerial self-diagnosis checks the diversity function and aerial connection. However, these results are not always meaningful. In this case, it is necessary to examine the field strength of the receiveable stations.
    Service mode

    In the Service mode of the radio, there is the possibility to display the quality and field strength of the radio station currently being picked up (not M-ASK and CCC). The displayed values lie between 0 and 15.
    15 corresponds to very good reception
    0 corresponds to very poor reception

    Proceed as follows to call up the Service mode:
    Terminal 30g ON
    Switch off the radio
    Switch on the radio again
    Within 8s for a duration of 8s, press the button for manual station-search function
    The radio switches into the Service mode
    Assessment of the reception quality in the test module

    If the result of the diversity self-diagnosis is OK, the field strength of the currently received station can be displayed in the test module. If one aerial has a noticeably weaker reception than the other aerials, the vehicle must be turned by 90 degree and the measurement repeated. If there is still a violation of the tolerance range, at least one FM aerial is defective. The defective FM aerial must be checked.
    Checking AM aerial / testing Rad_on signal

    In the diagnosis, the AM amplifier is inactive and therefore delivers level values with the AM amplifier switched off during an AM scan. To evaluate the AM aerial with the active amplifier, the test is concluded by switching the switching voltage from the diagnostic mode into FM1 / AM mode. With the amplifier switched on, the level values must be significantly higher than those with the amplifier switched off. If this is not the case, the Radio_on cable must be checked.
    Next you'll need a cheapo multimeter. Can you borrow one from a colleague?
    Inspect pin 1 RT/WS of X11012 for 12V as fed by fuse F59 5A.
    Inspect pins 2 (WS/BL) and 4 (BL/GE) of X11012 and make sure they are not shorted to GND. Also check they are not like 10 MOhm, suggesting a snapped cable.


    Might as well check fuse F59. If it's blown, it may have saved your amplifier from assploding.

    Hmmmm, sounds like passing the buck to me. Mine was repaired by my local dealer at no cost to me (they said it was a warranty item). Neither were they the dealer that I bought the car from so they had no obligations to do me any favours at all.

    Good luck getting it sorted, it looks like you have the assistance of someone knowledgeable on the subject already
