Dynamic Ride Control (DRC), Draining And Filling
Extracting, evacuating and filling the whole DRC line (lines/shock absorber and central valve) is performed with the DRC Filling Device :VAS 6544 Depending on the DRC system equipment in the dealership, the equipment may need to be modified or updated with the supplement or retrofit set to match the version of the DRC Filling Device :VAS 6544 . The following choices are possible:
Special tools and workshop equipment required
- Vehicle Diagnostic Tester
- DRC Filling Device :VAS 6209/4
The DRC Filling Device :VAS 6209/4 serves as a retrofit set to the DRC Charging Device :VAS 6209 already found in dealerships.
Special tools and workshop equipment required
- Retrofit Kit, DRC System :VAS 6209/5
The Retrofit Kit, DRC System :VAS 6209/5 is needed if the dealership has the DRC Charging Device, Pressure Pump :VAS 6209/3 and wants to upgrade the DRC Filling Device :VAS 6544 . The DRC System Supplementary Kit :VAS 6209/6 is also necessary.
Special tools and workshop equipment required
- DRC System Supplementary Kit :VAS 6209/6
The DRC System Supplementary Kit :VAS 6209/6 is needed to upgrade the DRC Charging Device, Pressure Pump :VAS 6209/3 to the DRC Filling Device :VAS 6544 . The requirement is that the dealership already has the DRC Charging Device :VAS 6209 . If the dealership does have the DRC Charging Device :VAS 6209 , then the Retrofit Kit, DRC System :VAS 6209/5 must also be obtained.
Special tools and workshop equipment required
- DRC Filling Device :VAS 6544
Required components from the DRC Filling Device :VAS 6544
- Not Required
- Not Required
- Charging Hose with Quick-Release Fastener
- Venturi Injector with Drain Hose
- From the DRC Charging Device :VAS 6209
- Connecting Hose
- From the DRC Charging Device :VAS 6209
- DRC Filling Device :VAS 6544
- Used Oil Container
- empty before starting the work
- Identification: red dot
Updating the equipment for the DRC system must be done one time only. It is not necessary to convert back again. The rest of the procedure for draining and filling the complete DRC system is described using the DRC Filling Device :VAS 6544 .
- Only approved oil may be used for filling or refilling. Refer to the Electronic Parts Information (ETKA).
- As a replacement part, shock absorbers and lines are delivered empty.
- Filling must only be performed at ambient temperature of approximately 20 °C.
- Lines/shock absorbers and central valves may only be evacuated and filled when they are installed and connected.
- While filling the DRC system, the gas reservoir to the pressure clamps is automatically checked for leaks at the piston in the central valve.
- Valves of filling device are open when ratchet levers are parallel to the flow direction.
- The valves must be kept closed during transport and storing the DRC Filling Device :VAS 6544 .
- Lines must not be bent.
Risk of eye injury.
- Wear protective eyewear!
