Audi 2001 A4, somebody hit my car in rear bumper, passenger side. There are few scratches on bumper, no dent though. I looked under behind bumper and noticed two bumper shock-absorbers on each ends. Passenger side where i got hit, shocker shaft was pushed in about 3 inches and came out again. It helped a lot. Body shop is saying that those shock absorbers are only one-time deal and needs replaced.I wander if it is right or he wants make extra buck as it will be insurance claim. Just curious. Thanks
