I keep losing air suspension lift option on acceleration

[zed_thirteen]

yes, I did mean lift.

I cant really describe the rate of acceleration. .If I accelerate quite quickly (not maximum warp!) then the lift option on the MMI becomes disabled. It tends to stay like this until I brake quite sharply (gentle braking doesn't seem to enable it) I think it might cruise for hours in the disabled state until fairly sharp braking occurs again?

I will check out the link you provided though - thank you
