I have a S85 with air suspension, and it seems to have developed an interesting clunk. I have the suspension set to "high" for my home location (primarily to ease passenger ingress/egress). As such the geo-aware function raises the suspension as I get close to my driveway, and by the time I pull in it's typically already raised. I've had it set this way for a couple of years, with no issues. Recently, I've noticed a clunk/rattle when the suspension travels as a result of hitting the incline of my driveway. My wife commented in it a bit back, so I don't think it's my imagination. The parameters seem to be: Suspension on high Steering cranked 80% to the right Hitting the incline of the driveway I don't notice it at other times, such as in my parking garage at work, where I go over speed bumps while turning, but the suspension is on low. This is also not the same popping noise associated with the steering unit, I had that previously. Anybody else experienced similar?
