There were only about 2000 RS4's sold in North America and this is predominately a US forum. So even 20 failures would be 1%. Assume 20% of owners come here, which I think is still high, and you can extrapolate a 5% failure rate. Look at the RS6 4 year failure rate and it far higher. To make things worse, once the DRC goes the first time, it becomes a guessing game as to whether or not it will ever be properly repaired at anytime in the future.
I feel pretty strongly that suspension components should last the duration of the warranty under "normal" use - which I think you have to define by the car and how it is marketed. The RS4 should hold up as a daily driver with a few track days mixed in since that is essentially how Audi markets it. Most of these RS4's are not even being tracked. So it is complete bullshit for Audi to limit the warranty on a DRC system that they brag about the purported benefits of. Build a product and stand behind it. Period.
I doubt we really disagree on this one.
