Front Air Suspension Strut With ADS PASM For Porsche Porsche Cayenne III 9Y0616039 9Y0616040

Q1: Which OE numbers are for which side? Front Left: 9Y0616039, 9Y0616039B, 9Y0616039C, 9Y0616039D, 9Y0616039E, 9Y0616039F, 9Y3616039. Front Right: 9Y0616040, 9Y0616040B, 9Y0616040C, 9Y0616040D, 9Y0616040E, 9Y0616040F, 9Y3616040. These units are side-specific — never mix left with right.
Q2: Which vehicles does this fit? Porsche Cayenne III — 9YA (SUV) / 9YB (Coupé), 2018–2024 with air suspension + PASM (electronically adjustable damping) — e.g. Cayenne, Cayenne S / GTS / Turbo / Turbo GT, E-Hybrid variants. Vehicles without PASM use different parts — do NOT fit this unit. Confirm model, year and equipment by VIN.
Q3: What do the letter suffixes (B, C, D, E, F) and the 9Y3 prefix mean? The suffixes are successive revision numbers of the same side-specific strut (base → B → C → D → E → F); the 9Y3-prefixed numbers (9Y3616039 / 9Y3616040) are the related variants for the Coupé body. Match the exact number on your original unit by VIN.
Q4: How do I tell the PASM/ADS version from the non-PASM one? The PASM/ADS strut has an electronic damping valve with a plug connector. If the original unit has no connector, it is the non-electric version.
Q5: Is this the complete strut assembly? Yes — air spring bellows, shock absorber and damping valve integrated into one unit, air fitting ready to connect. Direct replacement of the original strut.
Q6: Do I need to replace both front sides at the same time? Same-axle pair replacement is strongly recommended. An old unit on the other side causes uneven ride height and leveling behavior.
Q7: What should I pay attention to during installation? Release air suspension pressure per the workshop manual; disconnect the electrical connector cleanly and protect connector + air fitting from dirt; mount and reconnect; start the car, run the ride-height reset / system initialization; check left/right height and leaks before a road test.
Q8: Warranty policy and shipping damage? 18-month warranty under normal use. For shipping damage, inspect within 48 hours of receipt and send photos/video — the seller arranges a replacement.
Q9: Service life and maintenance? Depends on road conditions and climate. Keep bellows clean and check for cracks during routine service; if the bellows leak, replace the complete unit.
Q10: Are aftermarket alternatives available? Yes — NTY A-PS-030 (left) / A-PS-031 (right), at autoteile germany AT14646 (right side); genuine Porsche 9Y0616040C / 9Y0616040E are also sold as air spring units on spareto.
