This is my second RS4. And on this one, I can not get the so called Audi Experts to find the problem The front driver suspension knocks at low speeds. Audi thought that the problem was because there was not enough hydraulic pressure in the front right system, and decided to actually change the entire DRS system all together. Wow, i was impressed by their decision. They even changed the accumulators. However, guess what the problem is still there. they just don't seem to know what the problem is?

Does anyone have any suggestions for me?

 

Old thread but I am wondering if you found the problem yet. If its not the DRC, my next guess would be loose steering rack.

 

yes, after verifying the DRC again, the Audi Dealer finally found a lose control arm in the lower front passenger side. I just can not believe it took them this long to figure this out.
