C1a13 pressure doesn't vent from gallery
Hey guys - I've seen that there's been numerous posts about stir suspension, but this one's giving me the run around.
With a snap on solus I can send a command to declare the EAS and within seconds the car drops onto the tyres and following an 'enable suspension' command, the car picks itself back up in an errorless state until I ask it to change night from the dash of the car and it instantly goes into c1a13 and as a driver I'm faced with an orange ride night error light and the ride height switch is disabled again.
I take from this that mechanically each component works, because it is capable of venting the air and then reinflating evenly. So why does it still refuse to work?

Thanks for getting in touch. I actually have resolved mine. Here's my thread link posted below if you're interested. For me it ended up being a few different issues but the main ones were; tiny hole on the top of the reservoir (it did not look rusted from the bottom but the top side was), my original compressor most likely had an exhaust failure, my brand new compressor was a knockoff Dorman and not a genuine part so continued giving the same fault, and lastly I had some tiny leaks at my brand new Voss fittings. Best of luck to you. Hoping my repair holds!

Had same issue. 2006 Range Rover Sport.
In my vehicle the filters inside the desiccant dryer attached to the compressor pump were clogged, which resulted in slow venting when the vehicle was lowering.
I was also having issues with intermittent faults triggered by C1A13-64 error code (Gallery pressure does not decrease when venting) as well as Suspension in extended mode errors.
When the vehicle sends signal to lower, it opens the exhaust valve and the front right / left valves, which in my case caused an increase in the pressure on the gallery pressure sensor (because the pressure vents through the desiccant dryer, which was clogged, and the increased pressure from the front springs caused a spike in the pressure on the gallery pressure sensor when the front right/left valves open and the exhaust valve can't vent the pressure quickly enough).
Replaced the desiccant filters and desiccant, reassembled and so far it looks to have resolved both issues. Huge difference in the amount of time it takes the vehicle to lower since the air can now flow freely.
Hope this helps someone.

Where did you order the parts? The desiccant filters and desiccant?
Thank you,
