I noticed the opposite with my 405. In off road height the suspension feels noticeably softer and more compliant. |

What dia rims and what tyre pressures are you using? |

if its like that in GGS try it in M&Ruts. it opens crosslink valves for the suspension across axles in M&R Cheers

In the higher mode it should be softer, with more articulation, there must be something wrong with yours, maybe diagnostic check as starting point, if that inconclusive, then journey with technician from dealer over ground that causes the problem you describe. Consider change to 20" wheels if on larger at present, but what you describe does not sound like wheels issue only.

I don't take the Westie near any mud. But I noticed this on our P38. In off-road height, it's much much firmer. Which to make makes sense.

But the speed will be significantly lower at higher heights so impacts should be less. Cheers

I think someone needs to have a look (Tech) and check the suspension is doing what it should. It doesn't sound right to me as both my D3/4 and FF all seemed softer on raised suspension. Try the M&R to see if it does what it should. |

Move air but not more pressure unless more weight is added at the same time. The shape of the air-springs changes as they extend and IIRC the L322 air-springs were promoted at the L322 release to be shaped to provide a softer ride at off-road height. However with extreme articulation wheel down-travel becomes limited more readily which makes the ride harsh. |

Would the added weight of the 322 versus the 405 not create a more dampened effect on the rough stuff?? |

Does your car still have the original front struts? Lots were replaced under warranty and others later replaced at the owner's cost due to oil leaking from the dampers into the air-spring which restricts suspension movement. Sometimes when lowering to access height the oil in the air-spring prevents lowering which triggers extended mode because the suspension module thinks that the vehicle is resting on an obstacle.
