The factory fitted TCU had failed (the Motorola units like mine were notoriously unreliable btw) - so I fitted a Gen 13 ULF - all sweet now but not plug and play as you have to rewire the 54 pin plug

Sorted after 4 years - a working bluetooth system again - and with VR - well happy!

No - VR is built in on the later ULFs- any ULF with "mit ses" on the label has VR capability - may not be factory-enabled but readily sorted via DIS or a Resler I/F. No jumper plugs on the facelift E53s BTW

Someone must know surely ?

Blu-tooth installation conked years ago - just got around to having a look - fault seems to be no 'telephone on' signal from the TCU to the BM54 so the BM54 does not enable the front speakers during a call - they can hear you, you can't hear them. Decided to get the phone working again and fit a ULF ...

The key fob contains a rechargeable button cell the holder of which is soldered to the internal PCB - inevitably it eventually fails. You can get a repair kit off ebay for about £15 comprising a case, new rechargeable cell - and three new button microswitches. To access the PCB from the old key you ...

I am in the process of preparing to install an Intravee II and i-pod interface via the Alpine i-pod module. To this end I have made up a three-legged harness (using BMW supplied iBus cable lengths, pins and socket cases) one leg to connect my made up harness to the my vehicle's IBus plug as used by ...

[quote="brewer"] Similar problem here with the front seat heaters. Rears are working fine, but when I switch on the driver or passenger side it blows the fuse immediately. I suspect it's a loose connection in the wiring or heating elements and that will take some hunting down :( [/quote] If it helps ...

unfortunately have already bought a replacement module on ebay from a 2006 write-off - whatever I will sell it on

[quote="Steamyrotter"] It may have been tried, but try disconnecting the battery for a few mins and reconnecting. May reset it for you. If not at least its free to try it !!!! [/quote] Thanks - you got it in one. I actually pulled all the fuses associated with the heaters and the control panel, left ...

Thanks - I have had a search but can't find any solution on co-incident failure of the heater on both front seats - the common factor I suspect is a failure within the control module that incorporates the heater switches 

Both front heated seats have stopped working today - push either button, the three green LEDs light and then a second later, go out. The fuses are OK and all the electric seat movement functions are OK.

Any suggestions anyone?

Mine works fine with 7

Presume you have

1. un-zipped the drivers file

2. tried a different USB port

3. tried another lap-top

"Noise from behind heater control when car is turned off" - does this stop if you wait a while? If not:- 1. check if it is the blower running at low speed (this can be caused by the final stage resistor which you say you have replaced - with new?) - to do this, pull the 50 amp blower fuse - if the ...
