Maybe it's just getting old, but the ride quality has deteriorated. Ride at 'Lift' is about where 'Standard' used to be, 'Dynamic' is now harsh. Dealer says <I> am getting old.

If it were not air suspension I would be guessing shocks. What else then? Tires are Continental w/ 30k miles and good tread and proper inflation. Worn bushings ? What ?

Thanks for any suggestions
