TBH, I think I'm leaning (no pun intended!) towards an ACE related problem now. If you can get access to some diagnostics somewhere then that may be more enlightening.

Did you check the heights on the 4X4 screen?  Visiting from DISCO3.CO.UK

UPDATE, have just found out the problem......steering wheel sensor was at 18% now reset to 0 % and have not had suspension fault registered anymore.....it assumed I was oversterring by 18% causing ' vehicle to lean when cornering ' and then registering the fault which then snowballed and all the other listed faults started.....and breathe!!!!!!

Thanks for all your hints, but Mick Moores Landrover at Winnards Perch Cornwall you're top men Roger
