RRS l320 Getting message Suspension fault, checked code C1A20 Pressure increase to slow filling reservoir.
Comes on after about 2miles driving, go out after recycling ignition, then back on after another 2 miles.
Front & Rear corners height all look ok, about 460mm front, 470 ish rear, screen on dash showing heights all level. Compressor runs the same as usual.
Appreciate comments/help.

Hi if you are getting the "pressure increases too slow when filling reservoir" (C1A20) code and you can hear the compressor running okay, it may be you need to get the dryer cleaned/replaced and the valve refurb kit.

Hi Iomegas, Had thought the same as you, it seems most folk who get code C1A20 do just that, it sorts it for some &
not for others. will get the dryer kit & give it a shot. I would have thought that I would have had other issues with
height or compressor, not just the message/light on. very temperamental these vehicles!
Thanks for taking the time answering post.

Hi no problem i hope you get it sorted ok .
