Hello All;
I have a Disco 3 L319 2008 in my garage with a suspension fault.
Yellow light on dash and C1A1364 code on scanner - "Pressure does not decrease when venting galery".
We change a many parts of suspension, including two front air suspension spring, all 3 block valves, change compressor in 3 times, including a new compressor from china, every model Hitachi (the original).
We clear all the system 2 times, we test all of wiring, and it's OK.
But we can't solve this problem, a big problem, and i dont know what do.
somebody can help me?
Thanks people, i'm from south Brazil.

Chinese compressors are mostly junk , were the other parts changed because it was needed or just because of this fault ?

Very likely either the central valve block is faulty or the exhaust valve on the compressor is kaput.

Check the wiring under the expansion tank for broken or chafed wires a friend did all of the above only to find a wire broken. Fixed the wire all sorted

Hello guys.
Yesterday I replaced the original Hitachi compressor with an AMK, and the problem was SOLVED!
8 months of work, 6 Hitachi compressors (2 used, 2 repaired and 2 new Chinese), and simply assembling an AMK solved everything, not even programming was necessary.
HITACHI never again!
Thanks for your help colleagues.

Could be the software was set up for AMK. AFAIK they require different settings, AMK vs. Hitachi.

Hitachi will not run on AMK software but AMK will run on Hitachi software although at a higher pressure, for max life check you have AMK software installed. It can when others can't,
It will when others won't,
It goes where others don't.
