I am getting the suspension fault only normal height allowable error message on my 2007 LR3. I get the fault about 30-60 seconds after start up and during that time if the car is sitting idle, the speed fluctuates greatly till I get the fault but less so afterwards. I also get strong fluctuations when the AC is on. So I am wondering if this is a throttle body or MAS problem rather than the suspension problem. Does anyone have any experience with this? I am hoping to get some input before I dig into the process of clearing the TB and MAS, or before I buy 4Dcan so I can dig into the fault.

 

Clean the throttle body to take care of the idle, not related to the EAS issue. I recommend a full induction service, and checking the PCV valve, but just cleaning the throttle blade will fix the idle.

EAS fault coming on after that amount of time is indicative of the compressor not building pressure fast enough. This is usually caused by a leak in the dryer, but if it has been leaking for an extended amount of time, that can damage the compressor, as it will run much longer then it should, and overheat.
