While working on one of our favorite high performance Audi models, the 2007 Audi RS4, we saw one of the braided DRC (dynamic ride control) suspension lines start to seep fluid. Once the DRC system loses fluid, the suspension becomes compromised and a repair must be carried out at once. We love the engineering behind this suspension system and thought we would include a picture of the braided suspension line in its worn state to provide a heads up as to a potential safety risk. Audi models that use the DRC suspension are : RS6, RS4, and RS7. Call us if you have any questions about your vehicle's suspension (super-car or not).
