Questions about this item

How do I install the 15-529902 rear right air spring on my 2001-2004 Audi A6 Quattro, and what step is often missed?

Mount the air spring to the factory upper and lower brackets, torque fasteners to specification, then pressurise the system and check for leaks — skipping the leak test after inflation is the step most often missed.

What maintenance or replacement will the 15-529902 air spring need over its service life?

Inspect the rubber bellows for cracking or abrasion at each oil change; replace the unit if the bag no longer holds pressure or shows dry-rot damage.

What limit appears first on the 15-529902 during sustained heavy loading or towing?

The rubber bellows reaches its maximum safe extension before the metal end caps yield, so ride height drops and the compressor runs continuously if the load exceeds design capacity.
