i have an “activity plausibility “ fault that comes up on my front left wheel and would like to know what could be causing it.
I have had a few issues and replaced the following items which have cured the previous items, here is the list or replacements done.

compressor head and piston seal, now getting 16 bar
solenoid valve module under car, sorted open front left valve
both front ride height sensors and regulator rods, old rods stiff and changed sensors in case damaged.

i did notice that the activity plausibility fault came on after going around a roundabout if that helps
