Further update after putting F26 back in and rechecking fault codes:
I got front-cross valve issue back after having cleared it, and additionally got a fault code regarding the front height sensor which took a few attempts to clear.
I checked the front valve by putting it into rock crawl and the live values remained at 0% and N/A so suspect there is an issue with the valve block both with the connection and likely letting-by. What I don’t know now is if the height sensor fault was genuine of just thrown by me putting F26 back in.
I’m tempted to just cover all odds and replace both front and rear valve blocks and all height sensors whilst I’ve got the access.

Also hope I’m not being rude but did u check the rock crawl mode with a short drive up the road whilst watching the live data to see if that made any difference
Can also watch the height sensors to ensure u have 5Vdc in and signal Vdc out, that signal voltage goes back to the suspension ecu
Plus do u have a multimeter plse , thks

Hi, thanks.
What voltage would you expect the battery to be sitting at?
I’ve just put it on the tow charge now

As a side note ref the gap iid
Enter the live data menu and type vol in the search box and all ECUs that report voltage will be listed for selection , so u can check the suspension
Plus before I forget and to cover all the bases, have u looked at what the steering wheel angle sensor is at when the wheels are dead straight plse , thks

Hi,
I’ve just been out to check the live values and it shows voltage to all height sensors
With the steering angle sensor all options for live data relating to the steering angle show N/A. I’ve never looked at this before so I don’t know if this is right but it doesn’t sound right to me?

Hi, from what i know, crosslink valve operates in all "special programs" only if a twisted wheel condition is in act, so i suppose that is normal to read 0% while reading live from iid on a flat surface.
If your car drops without fuse 26, a leak is pretty sure (usually from the lower corner you find at morning).
With fuse 26 in, every 6 hours the car try to level all four corners lowering each single suspension to match the value of the lower one. During this routine the EAS ecu opens the crossover valves in order to balance the pressures inside the axels airbags. If a crosslink valve is stucked, you get the error code posted before.
So i suppose that you have first to check your rear driver airbag strut for leaking, than proceed to overhaul the front valve block looking for debris or stuck O-rings - Easy-Lift suspension module 4.0
