W221 Clues in Airmatic codes
Greetings All!
Just replaced compressor and block after rear end suddenly dropped to the deck. No warnings or issues at all up until this happened while driving.
After replacing the pump (which was original) and valve block I paid a local mobile mechanic to come and reset the system. I have the attached diagnostic report and am hoping experience found here will lead me to the remaining issue.
Im well experienced with air suspension having had six Range Rovers but currently without garage space to work on a car. In that respect im limited but with tools and some practical knowledge to get by on.
What puzzles me most and the reason Im not spraying soapy water everywhere (yet) is the 5286 code “…bleeding takes too long” which doesn’t seem like an air pressure loss but a depressurization issue. Also have codes for pressure sensor 5110 5111 and pressure release 5260.
Disregard FL and FR codes as report was prior to airing them up. The are now inflated and locked holding air.
Please take a look and tell me best guess what I should be looking at.
Thanks much. Cheers!

You did the compressor and valve block, now you’ve got 5286 bleed takes too long, plus 5110 5111 pressure sensor, and 5260 pressure release. That combo pretty much points at the valve unit side, not a corner leak. The bleed timeout happens when the exhaust path is restricted or the vent valve isn’t actually opening.
Actually I think you are confusing my post with the previous posts. I had been getting the malfunction symbol on my dash recently and just because I happened to have a new air compressor here, i swapped it thinking my problem may get solved but it didn't. The valve block had been replaced about 2 years ago, system had been relatively reliable but this malfunction symbol was an occasional thing every few days and it probably started around 2 months ago. Now it's almost every day. I do though think you're right, I'm leaning towards valve block. I just ordered one to see if that solves it. I did do all the Xentry airmatic tests and all completed successfully. I will report back after wapping the valve block.

or buy a decent diagnostic tool that’s not lying
@Billydv1 any work on air tragic must always start with checking the level sensors move freely on the silly seize up ball joints of the link rods... two at the front and a bend and snap off impossible to reach one above the park brake module at the back
Okay
so after hours of checking this out, I have finally found the issue. I pulled all the panels. checked the wiring under the floormat, by the air compressor, by the valve block, simply couldn't find anything. After running tests on Xentry, next set of tests involves check raising and lowering of vehicle. Front left was not lowering. Xentry instructs to disconnect air line, sure enough front left didn't lower. Grabbed a channel lock and unthreaded the brass valve on the top, now the strut lowers. This is the issue. The brass "Air Strut Residual Pressure Valve" is defective. Unfortunately not available locally. Amazon will send out for Sunday. Here's the valve

Reached out to Arnott in the hopes of also getting the original valves. Let's see if they will sell them to me.
for now, pulled the valve, drilled a tiny hole through from the bottom, appears to work, not getting the code again. I don't know why they use these, I'm guessing so that if the strut develops a big leak it doesn't drop too quickly
Just an update,
Arnott was real good about this, sent me a replacement valve 2 days later. If anyone ever needs, they will warranty with a purchase receipt but if you need to buy outright, they are listed in their online catalog in the Jaguar section
I wonder how many of these Arnott struts suffer this issue - on this forum for many years they had a great reputation then as of last 5 years its gone to rat**** with almost 100% of users struggling with almost immediate failures...
interesting info you have given - I thought you were on drugs when you first mentioned the problem
where exactly do they fit ?

After all it was the level sensor. It is welded to the rear axle or supposed to be. This weld failed and set in motion code after code. The sensor was still functional after I reattached to the axle. System aired up and hasn't had a problem since.

they clip on to the anti-roll bar - and snap off regularly - just as they can at the front
all three are a maint item - replace every 5 years - lube plastic seize up ball joints at least once a year

They are screwed in to the top of the strut, the car's air line screws into the valve. I guess it's better to have a replaceable valve rather than oem that appears to have pressure residuance built in meaning the strut would have to be replaced

So the clip as previously mentioned isn't welded to the rear bar, it clips on and there is a stop that locates it. Quite common for ball joint to fail if not regularly lubricated and to seize up breaking that clip. Some people will replace the clip and attach with a hose clamp. When I did mine, I dropped rear subframe, removed rear sway bar to install the clip correctly. If you keep it lubricated, it will last forever
