Dynamic Ride Control

Dynamic Ride Control

Only approved oil for filling and draining must be used.

Filling must only be performed at ambient temperature of approximately 20 °C.

As a replacement part, shock absorbers and lines are delivered empty.

Lines/dampers and central valves may only be suctioned, evacuated and filled when they are installed and connected.

When the DRC system is disconnected from the individual components (for example, the connection between the line/damper/central valve), the vehicle must not be standing on its wheels.

While filling the DRC system, the gas reservoir to the pressure clamps is checked for leaks on the piston on the inside of the central valve.

If, while filling of the DRC system, a pressure of 22 bar cannot be reached or continually drops, then check all connections for damage and leakage. If no issues are found on the outside, the gas reservoir to the pressure clamps on the piston on the inside of the central valve is leaking. Replace the central valve.

To attach or detach Charging Device (V.A.S 6209/2 ), system line to be checked must be locked at central valve to limit the quantity of oil leaked to a minimum and to prevent pressurized central valve from emptying.

Small oil leak with locked central valve which results from connecting or disconnected Charging Device (V.A.S 6209/2) at connection is not critical. Avoid repeating measurements because a small quantity of oil is removed from the system every time the Charging Device (V.A.S 6209/2) is connected. Every connection results in a pressure decrease of approximately 0.3 bar from the previous reading. Multiple repeated measurements decrease system pressure below minimum pressure or failure, which then requires a replacement of central valve of respective DRC line.

If the DRC system is being extracted, evacuated or filled, then this must be performed on the front and rear extraction/filling valves for each damper line. Observe the following when doing so:

CAUTION!
Always wear safety goggles!

Before removing or disconnecting any DRC components, extract the affected line completely.

Shock absorbers must only be filled when installed.

Vehicle must never be placed on wheels with closed, filled system and locked central valves. This inevitably leads to leaks and system malfunction.

Lines must not be bent.
