2003 AUDI RS6 User Comment / Complaint

I was driving the vehicle for a family vacation to nashville tn from milwaukee, and i started to notice that the rear suspension was very bouncy. i thought it may have been due to the extra weight of the luggage in the trunk, but as the vacation went on, the bounce got worse. by the time we were headed back to milwaukee, the bounce was so bad, that the car would lose control while going over rough highway. we took the car into the dealership for repairs, and were told that the suspension system had a leak in one of the rear shocks. however, because of the way that the system is designed, all four of the shocks have to be replaced in order to balance the pressure in each absorber. my car was out of service for 2 weeks, and the first time it was repaired, the mechanic stated that he did not have any training on how to fix the system. he did an admirable job, but the ride has not been the same since. the mechanic has since received training, and had to re-pressurize and replace all four shocks again. the second time the mechanic made repairs the system was better, but now the car is due for another repair on the rear suspension this week. it seems that this system is prone to leak fluid, which helps it maintain the proper pressure on all four wheels. i am worried that when my warranty is expired, i will have to replace this suspension system again, and it will be very expensive, or there will be a terrible car accident due to lack of control over rough highways.
