Gday

Starting a new thread appropriately titled with updates on this previous one: https://www.aulro.com/afvb/discovery-2-a/293615-melbourne-spare-sls-airbag-sitting-shed-short-term-loan.html

TLDR:

I had a leaky airbag, replaced it,
In the process, I created a leak at the thread at the compressor end, fixed it,
Inflated the bags to offroad height to test, they stayed there as I packed the car to the roof.... and then just stayed there. I got an SLS warning when I hit the speed threshold as the bags wouldn't go down.
I chased the wiring from the compressor loom to check for any issues I might have caused when I pulled the compressor off the chassis cradle, nothing obvious. I jiggled the ride height sensor plugs, broke the plastic housing on one in the process. Taped it back together and cable tied it in position. Also realised there is a crack in the bottom of the caliper on the passenger side (See photo)

I bled the lines at the compressor end, started the car, bags inflated to standard height. Hurray!
But they went back to offroad height essentially the next time I drove the car, which was 5 days later, no Offroad light on the dash, and the SLS warning light did not go off when I drove at speed. When I hit the offroad mode switch, it just blinked forever.
I pulled and checked fuse 28 - all good. Turned the car back on, offroad light is on! Press the SLS switch, blinks but no change to height.
I bled the lines again, they're now back to standard height.


Given this sneaked back on me pretty quickly when this solution last worked, I thought I'd post now rather than wait.

I'll update if/when anything happens, but in the meantime, if any of this sounds familiar, feel free to comment!

P.S. I do not have a Nanocom, I do have an iCarsoft LRII but not sure it is much use for the SLS.

Cheers

It probably isn't. If you are anywhere near the Dandenong Ranges you can borrow my Nanocom.

Recalibrate the ride height, you'll need a Nanocom for that.

Recalibrate the ride height, you'll need a Nanocom for that. +1 for that ^^^, you certainly need to calibrate then everythng will be OK, hawkeye can also do it... the reason can be that:
I jiggled the ride height sensor plugs, broke the plastic housing on one in the process.if you didnt disconnect the battery first.... if a sensor is disconnected or a bad contact occurs while the system is not in sleep mode it looses the calibration.
