L322 suspension woes

Sounds like a valve stuck open for some reason. Compressor is probably trying to fill the tank & airbags.

If you have missing crosslink valve(s), then who knows what re-plumbing has been done, hence the ECU cannot control the system properly.
 
big, quick update, fitted a second hand valve block, seems previous owner had both front struts connected to central valve block only, suspension seems to only want to go highest settings possible, even if I press the access button, the lowering light flashes, but the suspension raises, until it’s so high I can barely get in the car!!!!
 
further update, I have fitted and plumbed in the second hand valve block, but whatever suspension setting I try to choose, it just always kicks the compressor in and gets to such a height its undriveable, I now own a Hawkeye v5, is there a way of calibrating or resetting the suspension heights, also I have fitted 2 new height sensors on the front, all help appreciated, I'm determined to get this sported at home!!!!
 
Would like to keep this thread running as it’s an ongoing problem….. the new air bag seems to leak a little… the compressor air dryer was blocked ( now sorted ) however… the rear suspension still wants to go to extended mode!,
So what I’ve done to get over the problem in the short term is, remove fuse 15 to stop suspension doing anything, if I need to use the car, I replace fuse and inflate the new airbag using Hawkeye, once I’ve got it pretty level, i remove the fuse, this allows me to use the car for 4 - 5 days without a problem, after that, the Hawkeye inflates the leaky bag and away we go!!!
Just removed the window tints, car looks a lot better now..
 
Sorry only just seen this thread.
I don't think they all have a front crosslink valve. I borrowed a used ECU for testing and it threw up a faulty crosslink valve but my ECU didn't. Assuming the borrowed one wasn't faulty
 
Found this with a google search

Yes, it is normal. The x-link valves were deleted from production as a running change in 04 (so some early 04s have them, most do not) and replaced with a inline connector. That is how the truck car was sold new.
 
Blimey, so fitting a crosslink valve was a mistake…. I can revert it all back to normal ( as in, with no crosslink valve) then with the new sensors, I might get some sense out of the car, thanks for the responses, it means a lot…. Watch this space👍

Quick update, I’ve now changed all height sensors,
I’ve also got some links so I can remove the front valve block, and a reconditioned compressor, since last post, suspension is still doing the same, and now, the Speedo doesn’t work, I’m getting to the end of my tether with this car, I will fit the parts I’ve got, if it’s still the same, I’ll set it on fire and get a p38

Hi
My son and I are just going through pretty much the same scenario working on my car....compressor has been refurbished and new height sensors all round, rear and tank valves refurbished, currently got a leaking n/s front air bag (got both sides ordered) and the front crossover valve had been deleted but now reinstated by us...all exactly the same as your photo even down to the same air connection and witness marks where the valve block had previously been mounted.

We'll plod on and install the 2 new front struts but I did wonder (hesitantly!) if you ever resolved this issue given that the issues seem so similar?

Cheers Mark
 
I/We can probably offer some advice on this but I think it would be best if you start a new thread as I've read through and I'm not clear on exactly what your issues are. Accept that you are missing a valve block but what are the symptoms and codes you're fighting? You'll need to to get the new airbags in first of course.

Thanks for your reply.
As you say we'll get the new bags in and start a new thread if we're still up the creek!

In brief what drew me to the thread was seeing the photo of the missing front crossover solenoid valve along with similar 'back end' up in the air problems, mine is/was exactly the same.

When the 2 air struts are in we'll have replaced or refurbished most of the system apart from the control unit. I have the RSC Allcomms software to try to set levels up if necessary.

Thanks again
Mark
