Hello, I need to change the brake pads on my A6 avant 2.5tdi Quattro (2003). I live in France and am looking on a French car parts site but when I put in the car details it gives me quite a few different choices for front andrear pads. Can anyone tell me if tere is away of choosing which pads I should pick?
Here's a link to the site I'm using which should (fingers crossed) show the choices for the front pads.
