Technical Service Bulletin
Technical Background
The following components of the DRC system can influence the noise level:
• System pressure too low (see repair manual for nominal pressures).
• One of the four shock absorbers.
• One of the two central valves.
Tip: In the DRC system the shock absorbers are connected to one another diagonally (front left to rear right
and front right to rear left).
Production Solution
Not Applicable
Service
If you can clearly assign the customer concern to the DRC system, proceed as follows:
1. Check the existing system pressure of the DRC system according to Elsa at Repair Manual, Chassis >>
Suspension, Wheels, Tires >> 43 Self Levelling Suspension >> Dynamic Ride Control – DRC.
2. Use one of the available noise search tools (e.g. Pico tool or Chassis Ear) in the area of the shock absorbers
and decide at which of the shock absorbers the noise is the clearest.
3. Attach noise search sensors/terminals to the affected shock absorbers and the respective central valve and
decide whether the noise is generated by the central valve or the shock absorber.
4. If a defective part is found, replace it per the Elsa Repair Manual.
