Porsche symptom guide
Porsche PASM Fault
A PASM fault can involve controlled dampers, sensors, wiring, power supply, calibration or another chassis module. It does not automatically mean the damper has failed.
What the driver may notice
- A warning message, changed sound or changed vehicle behaviour.
- The symptom may vary with temperature, speed, load or drive mode.
- The event may be intermittent before it becomes repeatable.
Possible causes
- Damper electrical or mechanical condition.
- Ride-height, acceleration or steering input fault.
- Wiring, connector, module or low-voltage event.
- Incorrect coding or incomplete calibration after work.
Safe checks before booking
- Record the exact warning text without clearing it.
- Note vehicle temperature, speed, drive mode and when the symptom began.
- Check only visible fluid levels, tyres or obvious leakage where safe and permitted by the handbook.
What professional diagnosis may require
- A complete compatible module scan with event data retained.
- Physical inspection and directed electrical, pressure or mechanical tests.
- A controlled road test only when the vehicle is safe to drive.
Is continued driving risky?
Drive cautiously only if the vehicle remains level and controllable and the warning permits it. Stop for unsafe handling, severe noise or combined steering/brake warnings.
