Jochen,

Just had a play with using the LKM coding option on my E83. Reads the module OK, but had a very strange issue - the 'cold monitor' of rear blinkers is off by default so I switched it on. This caused the front main blinker on the LH side to stop working.

Initially this threw me as I thought it was a bulb out and couldn't understand why the warning didn't come up, but after testing the bulb & was found to be OK, I undid the change and it started working again.

Don't have a Navcoder loig I'm afraid ... but can probably get one if you need it. The LKM is for a 2005 X3 with adaptive Bi-Xenon headlights (if that helps).
