Well acutally 've read it in a different places , I have a lot of freinds who has 540 and M5 and they upgraded to CCFL angel eyes ... when u remove the headlights even on the X5 , you don't need to remove the bumper and the sensors , and after installing the ccfl angel eyes ..everytime the angel eyes are on , whenever the pdc comes on it will start beeping from the front .. a lot of people were talking about this problem ...

thanks for your reply anyway drex
