    HI A4 - Sorry to ask you directly. I have a 2007 Q7 and want to do the rear LED retrofit. I know i need to change the J393 Comfort module. The thing im confused is the component protection. When should i do it? After i installed everything or before installing the module. What isthe effect if the component protection is not removed? Can i drive the car to the dealer while the module is still protected?
