My 2009 328i now has the rear LED light failure and the dealer will not cover this under warranty. I see that you were able to get the LED boards out of the sealed plastic light housing. Before I start prying open the housing, do you have any details on how you did this? I believe you need to part the red lens plastic from the grey body to get at the LED boards - it looks like this is bonded together with an adhesive.
Any pointers you can provide would be helpful...better than buying a new light from BMW.
My outer lights are out and the main LEDS flash when 12V is applied. Oddly enough the main LEDS work fine if I drop the DC voltage down to about 9V.
