All of the sudden I feel the car juddering when driving over all surfaces.
*
It's noticable from the driversseat but twice as bad in the passengerseat where you're physically rocked around?!
*
It feels as if one tyre is completely flat or one of the wheels is buckled.
*
- All 4 wheels are tightened properly
- Original Porsche 20" wheels
- wheel nuts/studs not broken
- wheels not damaged
- brakes not sticking, not hot
- all 4 tyres at the correct pressures
- not visible damage to the tyres
- no side to side play in the wheels
- no knocking and/or scraping noises
- no juddering in the brakepedal
- no errorcodes
- airsuspension works on all settings, no errorcodes
- adjusting rideheight or suspensionmode has no effect

It seems like it's coming from the passengerside of the car and when I reverse is seems the front wheel is moving up and down??
*
Any ideas what this can be?
