Air Suspension Compressor Pressure Relief Valve — Wabco / Audi | OEM 4F0698311
Fix Air Suspension Compressor Overrun — Replace the Pressure Relief Valve.
A failed pressure relief valve in the Wabco or Audi air suspension compressor causes incorrect pressure regulation — allowing the compressor to over-pressurize or run continuously without building proper suspension pressure. This direct replacement valve restores correct pressure relief function.
Why Replace the Relief Valve
- Stops Compressor Overrun: Correct valve function prevents the compressor from exceeding design pressure limits.
- Restores Pressure Regulation: New valve allows correct pressure buildup and cutoff — restoring normal suspension operation.
