Air suspension pointers needed please

Hi guys, help needed please, I've had a adaptive dynamics fault message ping up on the dash (


60 plate autobiography), so i checked the obvious, the sensor on the drivers side wire had split, no issues, replaced with a repair kit and all good, however i've had it scanned as the message didn't clear and the code was C1A20-64. I've looked at the workshop manual and it gives the following info : Pressure Increase Too Slow When Filling Reservoir - Signal plausibility failure
Signal plausibility failure
Gallery pipe air leak
Compressor fault
Reservoir pipe air leak
Reservoir air leak
Intake filter
blocked/restricted
Intake pipe
blocked/restricted
Air suspension intake
silencer blocked/restricted
Corner valve stuck open
So I'm now a bit stuck as the off road height works and the compressor lifts it up no problems without any sag overnight so i'm guessing no air leak but i haven't checked properly yet. Has anyone had this problem before or know where or how to start checking any possible faults, thanks in advance and sorry for the long post!!

It's pointing to your compressor not filling the tank fast enough... worth taking it out (it's in the clamshell under the spare wheel) and checking nothing has got stuck in there and is preventing it from sucking air...

The compressors don't last forever though... Pete

Thanks very much!! I was looking for ages to find one that looked a bit more stately, but i'm so glad i waited, its a great colour combo and still turns heads, not bad for a decade old lump!
