Hi there, had the 2012 4.4 Westminster throw up a few issues recently. The suspension is working most of the time but occasionally says ‘drive moderately suspension fault’

I’ve put it on the computer and it’s given C13A13-64 PRESSURE DOES NOT DECREASE WHEN VENTING GALLERY

C1131-92 AIR SUPPLY

Been told it’s the compressor but I doubt this is true as it works most of the time.

Any help would be greatly appreciated 👍🏼

Thanks. Sam

check the filter isnt clogged up and spray some soapy water onto the compressor air tank...you might have a faulty one.. ... - .- -.

Thanks. I’ll try this asap

Try running for a while with the bronze silencer removed (fitted on the exhaust side of the system and located under the compressor cover)

If it is clogged it will increase the vent time and may cause the alarm you’re getting.
