Hi there, I'm an Audi virgin so bear with me if I confuse the situation. I bought a 2004 1.6 SE.... The brake pad wear indicator has lot up on my dash, can anyone tell me if it is the front or back set of pads that have the wear indicator, or can I buy both sets with wear indicators built in? Also, is there anyway to change the standard grille to the > 2004 facelift grille, I think it looks 10x better. Scott
