My wife has bought herself a 2007 3.6 SDV8, it has come with a fare few faults a lot of which I have managed to cure, unfortunately there are a couple that I can't get my head round, so if anyone can give me some advice please?

RLM
U0416-86R pending, invalid data recieved from vehicle dynamic control module.
U0434-86 invalid data recieved from dynamic responce module
ATCM
U0416-94 invalid data recieved from dynamic control module
HVAC B1B78-84 permanent pressure

if anyone can help me with what the codes are for please as my icarsoft doesnt tell me enough.

with the warning lights on the dash for suspension faults i can drive the car, but it wont raise or lower, but if i clear all the faults and try raising and lowering the car it works, but i cannot drive it as it makes a grinding sound from the front off side wheel area.

i am also getting a warning saying that cruise control is not available?

any thoughts please?
Thanks Tony

U Codes are a , old wiring/modules

My cruise control only works for about an hour then stops. Turn off the engine and it works again. L320 Range Rover Sport 2008
