Hello. Has anyone ever had trouble buying rear springs for an 2008 Audi A4 S-line 2.0 TDi?. I work in a a garage and all the springs listed for this model from our motor factors are the wrong size. I just cannot seem to find the right ones anywhere. The measurements listed for the car are approx 290mm in height and approx 135mm width across the middle. The ones i have on the car which look original (with grey and blue paint dots) are approx 250mm height and approx 115mm wide. The bigger ones will not sit right and hit against one of the arms. If anyone has had this problem and know the spring i need, i would appreciate your help. Thanks in advance. Gary.
