Known Issues & Watch Points

Air suspension compressor wear

Watch

On Cayennes fitted with air suspension, the compressor is a known wear item. Symptoms: slow levelling, warning light, audible compressor noise. Replacement costs are significant — verify system health before buying.

PDCC hydraulic leaks

Watch

Porsche Dynamic Chassis Control hydraulic lines can seep on older examples. Check around the PDCC pump and lines for traces of hydraulic fluid.

Intervals are general guidance. Always refer to your car's Maintenance Booklet and consult a qualified Porsche specialist. Known issues are documented based on commonly reported patterns — not every car will be affected.
