The DRC suspension system on my 06 RS4 has/is failing. I get a knocking noise at the rear every time I go over bumpy ground.
I want the ride and ride height to stay the same, so should I go for shocks or coilovers? Or should I shell out to try & repair the DRC system?
Any recommendations of where I could get this done in the Hertfordshire area would be most welcome. TIA.
