Anyone else had these problems !
2012 M3W
A few weeks ago the Main Beam Blue light came on when sidelights or dipped headlights ( and main beam) were switched on.
Everything else on the MOG worked fine.
At the time I noticed vaguely that with the headlights on you could not turn the engine off !
Now having investigated why this blue light comes on and found nothing obvious I disconnected the Indicator Module ( don't let the name confuse you it is a far more complex unit than that)
The Mog will even start without this module plugged in !!
After plugging it back in there are now no sidelights or headlights working yet the lights in the speedo indicate they are working.
Further confusion reigns in that when you switch the headlights on the ignition comes on and you can start the engine via the starter button without turning the key on.
Quite how the headlight switch can work the fuel pump/ ignition is beyond me at the moment !
Of course I checked all wiring, fuses, swapped relays etc to no avail.
It starts and runs fine but there is definitely some electrical crossover in the system.
Anyone else had similar problems ? which might point me towards looking in the right area for a fixable solution.
There is clearly some hidden electrical item that has failed and causing these problems, a wiring diagram would be a big help, Ian Brett has pointed me towards one in the Parts list.
