Air suspension fault codes???

I took a look at a friends L322 with full suspension lock-out (no LED illumination on switch controls).
I scanned the air susp ecu and got codes 112 and 118 which I've Googled to death but cannot find a description anywhere.
Anyway I cleared the fault codes and the system came back into life, the original prob was just after coming back from a dealer for an auto box replacement the front end dropped with the usual dash warning.
On the live data tests I've noticed that the resevoir is taking ages to get upto 11.8 Bar due to the fact that it eventually cuts out due to reaching 100 degrees c and won't cut in again until the temp drops back to 80 degc so I therefore I suspect the compressor is knackered and struggling to get to desired pressure before overheating.
But due to the fact that a replacement is £300 I want to be sure about this so if anyone could help with those codes I would be very greatful.
Thanks
Chris

What are you using to read the codes??

Tell your man to get hold of the RSW All Comms (about £200 delivered from the US with Import Tax) - great piece of kit.....

Have you done a site search? Compressor failure seems to be the usual cause, I think you can find a replacement for less than £300.

Yeah went through Google which directed me to here, and various other Land Rover/ Range Rover sites but no luck, I'm using my works Omnitec which is a great bit of kit but has no definations for these codes!

Look in the bar at the top of the page, there is a search button NOT Google, type in L322 compressor and see what you get.

Tried that and just got my post!!!!

A decent code reader will give you a description of the fault and not just the fault code numbers.
Get an "all comms" fault reader. Good bit of kit

When my air suspension lights went out it was my compressor on its way out.

When you reset the fault the compressor kicked in for 10 seconds and then it shut the system down as there was a fault with the compressor

Hope this helps
Good luck

Resevoir pressure dropping, keeps coming up on mine and its just had a new compressor, any ideas ? Could the actual resevoir be leaking slightly? Had 2 front air bags and height sensor plus resevoir sensor stumped

leak in connections or pipes at a guess - if compressor is new it can't be the solenoid seals or the pump piston - unless contaminated with dryer dust during fitment of new pump

Thanks
Its a 2003 L332 vogue v8 if that helps

Soapy water in a spray bottle will help you find any leaks around the reservoir . Checking over everything that was last repaired would be a place to check also.
