Suspension fault, what to replace next?
Advice please I’m losing the will to live.
I changed a ride height sensor as the info screen was showing the front wheel all over the place causing faults.
Giving the whip a little TLC I thought I’d also tackle other suspension issues.
My car was sagging at the front overnight, and throwing up suspension faults.
I’ve changed both front airbags and shocks as they were a bit old and crusty.
This didn’t fix it so I then swapped out the front valve block.
This has made it worse. Now it’s constantly faulting and I struggle to even get it up to standard ride height.
Today in the rain I fitted a new compressor.. it’s a bit noisy and now there’s no life at all in the front suspension. I’m going backwards fast here.
Any advice on what next. It’s like the front is getting little or no air. The drivers front is showing signs of trying but the passenger front is completely flat. The rear seems fine but is getting locked out by the fault.
Help.. please.. it’s a 2005 manualNarpy Grill, tinted windows, Smooth leather wheel (TLO Group buy), ACM fitted (thanks TLO), Rear door loom and Row 2 & 3 audio switch upgrade, RRS 20" wheel change, 285 Cooper LTZ's Sat Nav Mod (until I get a Faultmate upgrade), Front & Rear lamp guards. 4x4 screen now switched on - Woody32, Follow me home reverse lights - woody32, Auto release EPB - Woody32.

What’s the fault code it’s throwing when the light comes on?

I haven’t got a reader. I’m going on instinct and so far it’s been a mile off.

as changing the front valve block made it worse, go back there and check that you have all connections correct and that hoses to air bags are fitted correctly

Plus 2 on Globetrotter’s advice. It’s very easy (common) to have a leak at the Voss fittings after taking them on and off. They are reusable, but the internal o-rings wear out with use. I keep several spares because one always leaks after I refurb a valve block.
Did you fit a new valve block or rebuild your existing? Is the block OEM or aftermarket? Aftermarket are typically junk, but they should seal OK. If you’ve rebuilt, you may need to verify no internal O-rings are pinched or missing if the Voss fittings are OK.2008 LR3 HSE, 4.4L V8
