Air suspension warning light?
Click image to enlarge
Hello all,
I have a 2006/7 disco 3 which has an amber warning light on the dash. It looks like a picture of a truck with up/down and side to side arrows, I’m assuming this is the air suspension light?
I get a c1a20-64 code “pressure increases too slow when filling reservoir”
The vehicle suspension doesn’t sink at all over time and will lift and lower for the first 30 secs or so till the the ping and warning light come on.
I’ve attached a screenshot of the measured pressure in the reservoir. Rises quickly after start, peaks around 1300 and then drops off rapidly once the warning light comes on and the compressor cuts out. Quite quickly drops down to 600 and sits around 200 if left for a few hours.
After reading through a fair few posts on here I’m thinking I’ll check the reservoir for holes first. Is there anything else that should be high on my list?
Typically mot is just around the corner and I’m not sure it will pass with that amber light under the new rules?
And I’d like to fix it anyway!
Any help greatly appreciated

That error message could be the centre valve block (sits between tank and pump) or the pump filter medium.
