Need your help guys... I just bought a 2007 Audi A3 1.9TDi. I have noticed a few 08/58 plate A3's with LED strips in the front lights? Couple of questions: What do i need to do if i want these LED headlights, are they a direct swap? Also, I want to upgrade the front bumper to a S-line bumper. What parts of the bumper do I need exactly. As i have seen people on here talking about lower grille, upper grille etc. Thanks in advance for your help.
