Please someone HELP! Can't find front coil spring anywhere for my 2000 plate A6 S6 C5 2.7 BiTurbo Quattro. I've removed the strut and not sure if the colour code on spring is 1 brown 1 pink or 1 yellow 1pink. Audi dealer parts department gave me a part number but i think it's the wrong one. Any HELP appreciated. Thank you.
