2005 Vanden plas... ( NY)
Removed front Air shocks (while replacing Upper Control arms) Everything went back fine and followed Tips on the 'Arnott' / Bilstein video.. Only problem is, Started her up expecting to hear compressor kick in and fill the shocks..? Nothing! Silence..
I'm wondering IF it's because I left the key in the ignition? (Bilstein says to remove key) And / or I never disconnected the battery prior to working on it. ANY ideas on how to Kickstart the air system again ? about to check all the fuses.. Need for work tomorrow! Everything worked fine just prior to work.
any advice much appreciated! GG

 

Have you tries driving it around for 15/20 minutes?

 

+1
Drive the car (slowly) for some time.
Also try repeated igition on/off cycles and moving the car.

 

Thanks lads.. Will try ( later) n get back!

 

Hi GG,

+3 on driving the car to see if it is just in Jacking Mode.

If driving doesn't bring it back to life, I think at least one member had success doing a "hard reset" of the system: disconnect the battery negative cable and hold it against the battery positive cable terminal for a few minutes or more. You don't have to disconnect the positive cable from the battery because the battery will not be in the circuit. This clears some or all of the Keep Alive Memory (KAM) in the Air Suspension Control Module (ASM) and may prompt it to once again recognize the low suspension and run the compressor to repressurize the system.

Please keep us informed.

Cheers,

Don

 

Thanks for the suggestions.. ( feel daft.. should've tried driving it first!) Reversed it out of garage (30ft) .. then fwd.. back again & let it sit. In a minute or two..heard that lovely sound that only an Air Mattress could love!
lol.. I think in my blocked up, head cold state of mind.. I got paranoid about missing a few steps & thought I could damage the bags.
Next up.. those creaky, groany Front sway bar bushings..


Cheers mates..

Great to hear your "up and running".

 

Are you totally serious about holding the negative - battery cable to the + terminal " for a few minutes" ? How have you dealt with the explosion?

 

Disconnect them both first, wait a few min's, then touch them together.

 

Disconnect both cables, wait 5 min, then touch together

 

You actually do not have to disconnect the positive battery cable. Just disconnect the negative cable and touch it to the positive cable still attached to the battery positive post. If you think about it, the battery cells will be completely out of the circuit, so there will be no current flowing through any of the vehicle's circuits except for the very tiny currents from the keep-alive memory capacitors as their charges drain to ground/earth. No explosions or other adverse effects. I've done this many, many times.

Cheers,

Don

 

Hello gemjag,

My advice is to follow "Bilstein"'s instructions on that video, (especially from 07:24 - 08:29):
"Lower the vehicle to the height of 380mm, (front)... then after 2 min. while engine is run - lower the vehicle to the height of 340mm"


And, from https://www.pdf-archive.com/2016/07/...rkshop-manual/ follow page 142 instructions:

Hi Clapton7,

My anti-virus program did not like the above link, but the entire pdf X350 Workshop Manual can be safely downloaded in six sections from the How To Quick Links thread on the home page of this X350 forum.

Hello Don,

Allow me to recommend and forward you to Google's well-known "virustotal.com" website and inspect what do
they think about the "https://www.pdf-archive.com/2016/07/02/x350-workshop-manual/" link I attached...

And at the same time... to review again who is/are your anti-virus software code writer/s that you are using and maybe
update them for the paragraph's above results.

Regards.

I tried a "hard reset" with the battery and had no luck. I had to just drive the car. It fixed itself once I pulled forward a bit and then backed and did that a couple times as I was turning around in my driveway. It fixed it just after doing that a couple times. All good. Thanks everyone for the tips here.

 

Does anyone know anything about a 2003 lincoln navigator this is the only free page i found that will openly let me ask aquestion about my air ride suspension. I replaced my front cv axels and now the suspension wont kick on. it doesnt sound like my air compressor is kicking on. I had it rise one time after my new parts were put on and now its shot to the floor and wont rise. Ive tried leaving it run for 10 minutes and took it slowly down the road for about 15 minutes and still nothing. Any suggestions?

 

Hi BigWhiteTowTruck,

Welcome to the Jaguar Forums!

The first possibility that comes to mind is that the air suspension control module has entered Jacking Mode, which disables the air suspension compressor. On the Jaguar X350, driving the vehicle over 2 or 3 mph will exit Jacking Mode, re-enabling the air suspension. However, the air compressor will not run until vehicle speed exceeds 25mph. But if you start the engine and leave the transmission in Park, the compressor should run and re-charge the system.

Another possibility is that one or both ride height sensors may have been disconnected or damaged in the process of replacing the CV axles. Except for the earliest cars, X350s have only one front ride height sensor.

For a full explanation of the Jaguar X350 air suspension implementation, see this post:
