When you say it "holds at about 224psi", do you mean the gallery sits at that pressure? There was a software update issued to vent the gallery down to just over atmospheric to prevent the compressor starting into a high head pressure. That also helps detect internal leaks where the valve leaks the bags back into the gallery as you can see the gallery pressure slowly increasing.

It drops down to around 15 psi after its vented, I just had to move the car and it had dropped slightly over approx an hour.
No visible leaks in the struts at current height and they are about 6 years old.

Have you done the "pull the fuse" test for 24 hours to see if it reliably moves? That's what pointed to my front valve block which started this thread (post #10). Now I have the same problem on the rear because I didn't do the rear.

Having said that, the only fault code was the one in the thread title, because it was leaking back into the gallery. Your "slow to raise" fault would seem to indicate a compressor issue on top of a leak.

Edit : Oh, and also because I have a fat arse, when I exit the vehicle it'll often fart and drop because with the removal of my ballast the suspension raises out of tolerance. Sometimes it's almost immediately, and sometimes it takes a little while.

I've just pulled the fuse and will check on it tomorrow, even though my main compressor was worn my spare is good and have even lent it to a friend while he ordered a rebuild kit for his so i know that one was good.
2 annoying issues that happened at the same time .
