I went to 2 different BMW specialist shops they both quoted me over $1,500.00 to repair the issues I was having with my lights and other electronics not working. I did some research and found The ECU Pro online I followed the instructions and watched the videos it was the FRM module it was relatively easy to take out and send it to be diagnosed they did and fixed my unit sent it back in a few days. I reinstalled it and every issue was gone what a relief, this saved me over a thousand dollars I also called and they were very helpful and informative I highly recommend The ECU Pros Nick
