Air suspension trouble c1A13

Replaced the Hitachi unit with a amk about one month ago, and now suddenly I would get the fault ; C1A13 Pressure does not decreases when venting gallery.

I Took apart and cleaned the rear and middle valve Block and I replaced the front one (due to the White powder issue) at the same time I replaced the compressor.
Could it be the pressure switch in the middle valve Block?

Sometimes it worsk fine, other times I would get this fault, so it is not constant.

There is also a leak at the back of the air supply exhaust silencer (!!?) making the car fart a bit louder when parking.
When searcing for a replacement part I can see that they are stated "only for Hitachi compressors" making me think the routing May be a bit differnet with the amk unit.
