ACTIVE CURVE SYSTEM malfunction in instrument cluster. Topic number LI32.34-P-058736 Version 1 Design group 32.34 Roll control (WR) Date 03-21-2014 Validity MODEL 166 with AIRMATIC (code 489) and ACS (ACTIVE CURVE SYSTEM, code 468) Reason for change Reason for block Complaint: ACTIVE CURVE SYSTEM malfunction in instrument cluster in combination with the following fault codes in the ACS control unit: P100000: The oil pressure at the front axle is too low. (Veh. up to approx. 7/2012) P100200: The oil pressure at the rear axle is too low. (Veh. up to approx. 7/2012) P1C9C00: The oil pressure at the front axle is too low. (Current veh.) P1C9E00: The oil pressure at the rear axle is too low. (Current veh.) In addition, the following complaints may occur depending on symptoms: Gushing/flow noises from the front or rear axle area when cornering. Oil leaking via the ACS reservoir. Cause: Residual air in the system. As a result, a fault code is logged and the message appears in the instrument cluster. Remedy: 1. Check intake line for tight seating at oil reservoir and at pump (it should not rotate; replace if necessary) 2. Fill oil reservoir up to upper line of 60° marking 3. Start engine and observe fill level 4. If the fill level drops, switch off engine and correct oil level, multiple times if necessary, until it can no longer be detected to drop. 5. If the fill level is stable, run engine at idle until there are no more bubbles in the oil reservoir 6. When the oil reservoir is free of bubbles, start the bleeding routine. 7. If there is severe foaming in the oil reservoir, abort the routine and top up the oil again, then run the engine until the reservoir is free of bubbles. 8. Restart the bleeding routine, observing the fill level and watching for foaming. 9. When the foaming stops, the high-pressure test can be started. 10. If the test is passed, again check that the fill level in the reservoir is at the correct level; correct if necessary.
