On the 2003-2025 Porsche Cayenne, cayenne models equipped with PASM air suspension suffer from compressor burnout and air strut bladder leaks. The compressor overworks to compensate for leaking struts, eventually overheating and failing. Air strut bladders crack from age, UV, and road debris, causing the vehicle to sag overnight.

This issue also affects: Lexus LS, Mercedes-Benz CLS-Class, Mercedes-Benz GLC

Common Symptoms

Vehicle sitting low on one or more corners
Suspension fault warning on dashboard
Compressor running continuously
Audible air leak from wheel wells
Harsh ride quality

How to Fix

Replace failed air struts and compressor. Consider replacing all four struts simultaneously. Arnott offers quality aftermarket replacements at lower cost than OEM. Some owners convert to coilover suspension to eliminate the air system entirely.

On the 2007-2025 Porsche Cayenne, the PDCC active anti-roll bar system uses high-pressure hydraulic fluid to control body roll. The hydraulic lines, actuators, and seals develop leaks over time, causing the system to lose pressure and trigger fault codes. Repair costs are extremely high due to the specialized components and Porsche-only fluid requirements.

Common Symptoms

PDCC fault warning on dashboard
Excessive body roll in corners
Hydraulic fluid leak under vehicle
Creaking or groaning from suspension during cornering
Warning to reduce speed message

How to Fix

Replace leaking hydraulic lines, actuators, or seals. Use only Porsche-specified PDCC hydraulic fluid. Some owners choose to disable the PDCC system and install conventional sway bars as a more affordable long-term solution.

TipIf PDCC repair quotes exceed $4,000, consider a PDCC delete with quality aftermarket sway bars — many owners report improved ride quality and zero maintenance.
