Looking for some advice as I don't seem to be able to find any info on this particular issue on the forum.

I get an intermittent fault bong on my dashboard with yellow exclamation mark detailing 'Suspension Fault'. When I switch the car off and then restart it resets the fault but a few miles later the fault will return.

I've pugged my IID tool in and the only fault that is read on the suspension is:

C1130-66 (AF) Air spring air supply - Algorithm based failure - signal has too many transitions/events

I am assuming this a a sensor fault but which sensor I do not know.

The car seems to be slow to rise when lifting to Normal/ Off-Road height but I don't know if this associated with the fault or a issue all of it's own. Also it seems to drop passenger side front when parked up ad left.
I'm hoping that is a sensor issue and not a bag gone but I don't think I'm that lucky.

Any advice/ help would be greatly appreciated! 2011 RR Vogue 4.4 TDV8

Problem solved:

(For anyone searching for the issue in the future)

Issue was with the front air spring. Pin holed somewhere due to the age I imagine. Changed for a new bag on the corner that was dropping over night. Suspension stopped dropping and alarm has never came back in since.

From my searching round the web I've found it is likely to be the valve block leaking or the air spring. Bubble tested my valve block to discount it. Bubble tested my spring to no avail but took a gamble and ordered a Aerosus bag.

Ran it for a week and been sweet ever since! 2011 RR Vogue 4.4 TDV8

How did you isolate which front bag? Im having the same issue, I currently have the negative terminal pulled to see which side drops, I figured if it valve block both will drop, and if it only one then one corner will drop since it can't auto level with no voltage
