Was having the same error (C1A13-64) and lifting issues as you. I pulled the filter and let it soak in some CLR for 10 minutes, blew it out, then put it back on. So far, raising and lowering are not causing warnings. I also ordered a service kit from 4x4AirSeals to replace the media and seals. Thanks for posting!
Might do that actually. I did wonder why there was a filter for the exhaust, although I imagine it’s just to stop foreign body ingress? Is this where the air enters the system as well, I can’t remember? Since having ‘serviced’ the fitting, my suspension has been faultless (although I won’t say that out loud as I wouldn’t want to anger the Landrover Gods!) 😂

Drill that sintered brass filter and will help too. Common issue and the fix is to drill it through.

@@Dadulthood It’s the exhaust only. Remove it. Drill it through and refit.
The compressor and air suspension will not operate correctly with the Tailgate open!!! The pump will work harder and cancel out!!
