Audi DRC Suspension Repairs & Refills in Guildford
At CT Cars in Guildford, we now offer professional repair and refill services for Audi’s Dynamic Ride Control (DRC) suspension systems – fitted exclusively to RS models such as the RS4, RS5, RS6 and RS7.
What Is DRC Suspension?
Dynamic Ride Control (DRC) is Audi’s advanced hydraulic suspension system designed to reduce body roll and improve cornering performance in high-performance RS models. The system links diagonally opposed shock absorbers using hydraulic lines and a central valve system to keep the car stable during dynamic driving.
How DRC Works
DRC automatically adjusts damping force during acceleration, braking, and cornering – without relying on electronics. Instead, it uses oil pressure to control chassis movement, resulting in a sharper, more responsive driving experience.

Which Audi Models Use DRC Suspension?
DRC is only found on specific high-performance Audi RS models. At CT Cars, we are fully equipped to repair and service DRC systems on the following vehicles:

Whether you drive a B7 RS4, a C6 RS6 or a newer RS7 Sportback, our team understands the high standards expected by RS drivers. We’ve built a reputation for precise workmanship and personal service – making us a trusted name among local Audi RS enthusiasts.
Common DRC Suspension Problems
Over time, the DRC system can develop faults due to wear and pressure loss in the hydraulic lines or valves. Symptoms of a failing DRC system include:
- Uneven ride height
- Knocking or clunking sounds from the suspension
- Excessive body roll
- Oil leaks from dampers
- Increased vibrations in the pedals

Frequently Asked Questions
What is the cost of repairing Audi DRC suspension?
The cost of repairing DRC suspension varies depending on the model and the extent of the problem. At CT Cars, we offer competitive pricing and will always provide a clear quote before any work begins.
Can you recharge the DRC suspension without replacing parts?
Yes, in many cases a hydraulic fluid refill and pressure balance can resolve performance problems without needing full part replacements. We’ll always assess the system first and recommend the most cost-effective solution.
How long does a DRC repair or refill take?
Most DRC services can be completed in half a day, depending on the complexity. We aim to get you back on the road quickly, without compromising on quality or safety.
Is DRC suspension better than air suspension?
DRC and air suspension serve different purposes. DRC offers sharper handling and performance ideal for RS models, while air suspension provides comfort and ride height adjustability. Neither is “better,” but DRC is more performance-focused.
Do you service DRC systems for older RS models?
Yes, we’re experienced with both newer and older RS models equipped with DRC systems. Whether you drive a B7 RS4 or a newer RS7, we have the tools and expertise to help.
Will a faulty DRC system affect my MOT?
While DRC faults may not directly cause an MOT failure, problems like leaks or imbalanced suspension can lead to advisory notices or safety concerns. It’s best to get it inspected and repaired promptly.
