L320 air suspension fault

Drdeathv8 · Jan 7, 2020

Hi chaps... i know... its dark, and wet out so not ideal time to go playing find the fault..

So..... driving along and suspension deflates. Brings up fault.

Stopped and raised suspension.. which it did..

Drove off and deflated again...

What do we reckon? Burst an air spring?

Help appreciated... I know nothing about air suspension...

Hi

really need the faults codes read as it can be a few things from a new compressor , faulty valve block , relay etc the list goes on

a quick question does it drop over night plse

plus do u get a red or orange warning light on the instrument panel when the error comes up

cheers

It was fine until last night. Currently has a red warning light on the dash. Deflation takes literally less than 20 secs. I would say compressor is working as it raises, albeit very slowly front raises first from what I could work out

Hi @Drdeathv8

what year and engine does ur RRS have please

Have u got a multimeter and ok with testing a few basic things as can certainly run through a few things to see if we can pin it down with some basic tests

Suspension slow to raise can be , worn out compressor , leak

back should raise first , mainly so the headlights don’t glare people when the vehicle is started up

have u got any manuals etc ,

hope that helps a little and happy to talk u through a few things

Hi

No probs , I’ll send a link over for a workshop and wiring manual

thks ref the details, so here goes, lol

1) does the suspension drop overnight
2) if the suspension is at its lowest height setting u press off road height , does the warning symbol come up as per picture but in red

hope this at least helps to get ur started
