Common ABC faults and symptoms
- Clunk over speed bumps
- Pressure accumulators have lost their nitrogen charge. Usually the first and cheapest ABC repair.
- Car sinks overnight
- A front or rear valve block is leaking internally and the car rises slowly on start-up.
- One corner sits low
- An ABC strut is leaking past its plunger seal, often with wet fluid on the strut body.
- Whine from the engine bay
- Tandem pump wear. The same pump drives the power steering, as on the W220 and W221 S-Class.
- Fluid under the front of the car
- Pressure or return hoses near the pump have split from engine heat.
