I just had a poke around under the car, and there is no visable external wire / tube etc coming from the shocks.(for adjustment) When using the “off-road height” on the full air suspension, the downward travel is not stopped or sufficiently slowed by the shock absorbers until an almighty metal to metal thump. This happens at slow speeds driving simple off road tracks on either of the front wheels. (note, downward travel)
