Air Suspension Compressor Failure
Thanks lads for all the help.
I had the fault messages as described on this site ("suspension fault - locked in normal height" and "vehicle rising slowly") and , not wishing to hand vast amounts of folding to the Main Stealers, did some googling.
Most, if not all, of the USEFUL information was from this site (thanks Bodsey and Disco Mickey).
I initially hoped it was just the air drier but ended up with fresh silica gel, new exhaust valve and piston seal (landyair on fleabay - expensive but effective) and now appear to have my D3 working again.
Everyone mentions the top bolt on the support frame!!! I managed to remove it using a LONG 10mm spanner but trying to put it back was impossible (rugby player's hands) and, after much swearing, decided to modify it by cutting the frame to change the hole into a slot. I could the start the bolt in its thread and then fit the unit and tighten all three bolts.
I hope this is helpful to other members.
Cheers

I've just followed exactly the same route and done the cut out bit, great minds think alike, except mines a failure, still get the same fault messages, Iid tool says motor is overheating
It can when others can't,
It will when others won't,
It goes where others don't.

Hi MD3PO.
Don't be too disheartened - mine did exactly the same!
I suspect that the system has partially depressurised with the faulty compressor and when working hard properly to repressurise (200psi) said system it has shut down - compressing air produces heat.
There is reference to this on another thread. Let it cool down and try again. This is conjecture on my behalf but it has worked with mine.
The manuals say that the system has to be separately repressurised after being fully discharged which would suggest that the onboard compressor is designed to top up the system as opposed recharging it.
