I just finished installing my water pump on my 77,000 mile C6 A6 Coupe with the F55 option. While doing it I had to get access to the radiator drain plug so I jacked up the the front of the car and blocked it off on the passenger side and then I jacked up the rear of the car for a minute and then put it back down. I think the front of the car went up about 12 inches which gave me enough room to get to the drain plug.

Now here's the problem... I started driving the car and I noticed the rear passnger side of the car the upper tire well sits about an inch lower than the rest of the cars tires in relation to the tire well. So the rear passenger side of the car has sunk about an inch.

Does this mean I need a new $700.00 Magnetic shock? Shouldnt I get an error on my DIC about the bad shock? If it is the shock can I go with four cheaper shocks and loose the F55 Function? Will it show up on my dash as an error code?

Does anyone know where I can get a cheaper shock than the $700.00 one and it works the same?

Is it something else altogether that I'm missing? Maybe the car had sunk before I changed the water pump, but I didnt notice it until after that. Can I take the shock off and stretch it out again see if it will work? (I'm grasping for straws sounding kinda stupid, but I'm brainstorming.)

Due to the economy I need to save as much money as possible and go with the cheapest solution. I can come up with the $700.00 but I really hope I dont have to.

Lastly is there a C6 graveyard where I can buy a used F55 shock that would work?

Any help from the forum would be deeply appreciated.
