yeah, I replace AE on my 535i so I need to recode; not sure if my BT tools will do it though. But again I these are H8 type 20W Cree bulbs (it's using 4 Cree XB-D leds in a bulb that put out 1200lumens total), so if they are blown I am sure someone is making H8 tpe with XP-T led chips at around $50 for a pair in a year or so (these one suppose to be 1800 lumens), so maybe more reason not to code the LCM module
