the question is about the programming - there is a line in the LCM programming code that states "LED taillights - nicht active"... I don't remember exact spelling at this moment, i would need to dig up the old file to look it up, but...
I wonder if there is a member who has the LED tail lights, does not have a capacitor (or can remove the capacitor rather easy) and is able to use NCSExpert, could change the line in the programming code to see if the LEDs will stop flickering AND will retain the BFD ability...
Any takers?

When I first put my LED tails in my 2006 X5 a week ago, I had flickering despite having coded the LED tail light option in NCS; and I thought the LED tail lights were too dim ( I could barely see they were on in bright sunshine, although the brake lights were brighter.)
I turned off all cold monitoring as well.
I ended up changing the PCM setting, really just by trying one setting, then test, then try another, until I was happy there that there was no flickering .
