Suspension fault 2007 range rover vogue

Hi all
Hopefully somebody is in the know!since yesterday my RR has started to flash on the dash, suspension fault, do not exceed to 30mph,it also will not go into access mode,instead it will go into extended mode! I think i may have found the problem,the air compessor exhaust muffler.i have removed the gold coloured muffler and it a peers to be full of blue dust,does anybody know if I can test the suspension with the engine running with out the muffler in place?
Thank you all for your time

Should be able to...just need to clear the stored faults in the ECU I would think before it works correctly, unless it is just a soft fault which will reset itself when you turn the ignition off!

all good,removed the air compressor exhaust muffler,start her up,suspension goes in all modes without any trouble at all. No more suspension fault!
thanks for all you replied either on the landy page,or on the rr page

Don't forget to change the air dryer as suggest or its going to go tits up

Will change the air dyer ASAP once back in the uk next week

Cool hopfully leaving off the muffler might just stop it clogging up or a tempory bypass a bit of moist air won't do any harm over a short period

Air exhaust muffler and dryer changed
