hi,
can anyone advise with what the air suspension pressure should be on an 07 RRS, I am currently getting 1500-1600 Kpa, but get a suspension fault, I'm trying to establish if it is a worn compressor or a pressure sensor problem

many thanks

Not sure what pressure you're meant to get but the vehicle should raise and lower smoothly, if it's notchy when it lifts then your compressor's more than likely on the way out.

Whats the error you're recieving ?

The fault is suspension fault normal Height mode, I need to check the whole system including the reservoir for leaks also the intake filter for blockages etc. I have since found out the pressure should be about 16 bar and I'm getting about 14 bar so it could be the compressor requires an overhaul or one of the above
Thanks

It should raise to 1779kpa
It's error because it's not getting up to pressure.
Either compressor if fubared or you have a leak.  Bodsys Brake Bible

Thanks for the info. Compressor is booked in for a removal and refurb. Lower collapsible steering rod getting done at same time, hopefully that's it sorted for a couple of months LOL
