Air suspension compressor wear from constant cycling

Land Rover Range Rover Sport Air Suspension · 2012

If one corner of the vehicle is visibly lower than the others after sitting overnight, the air suspension compressor is likely running overtime to compensate for a slow leak in one of the air struts - and that constant cycling is exactly what wears the compressor out well before 100,000 miles on this generation. It is not a safety-critical issue day to day, but ride height and handling degrade gradually, and an already-strained compressor left running against a leak will eventually burn out entirely. Fixing a leaking strut promptly is the cheapest way to protect the compressor; if the compressor has already failed, budget for replacing it on its own unless a strut also needs attention at the same time.

Track this fix against your exact car, save it, and get alerted the next time it's due.
