| Suspension pressures reach > 245psi then amber warning |

The dreaded suspension waning light
Suspension line pressure increases and then as it almost reaches 250psi it drops straight down to ~15psi and the dreaded suspension warning is displayed. code U0421(68). Can't tell which comes first. pressure drop or warning light. They're so close together. Recorded this event while driving (I wasn't touching the phone, promise!).
Suspension dimensions don't seem to be effected. The warning light started coming on a few months ago only when it was cold in the morning and cleared after turning off/on. Now it's almost every drive although for 2 days this week it didn't have an issue. Suspension doesn't seem to drop overnight but I'll be looking at that more closely over the next few days.
When I got home I turned off/on and I think the pressure reading was immediately showing 244psi.
Can someone point me to a diagram for how all the valves, reservoir and compressor are connected so I can try and debug this. Hoping it's not a new compressor. 2015 Disco 4.
