So… I have still not fixed an issue that started around 5 weeks ago that I’ve lived with.

Usually within a mile or two from being cold or reasonably cold I get a ‘hdc fault’ then ‘suspension lowering’ I then pull over and turn it off and on and no faults. Drive 200 miles after with no issues.
No obvious faults logged. Sometimes the ante is upped and you get a cheeky transmission fault limited gear selection and park break fault as well as the above.
I don’t believe it’s steering angle or height sensors as it doesn’t come back after the initial restart…

When was the last time it had a new battery ?

We chased similar fault on my mates car for a fair bit it turned out to be a faulty height sensor

How did you work out which one? Current stable:

We changed the one on the side his so called mechanic worked on when replacing the lower control arms etc. Got lucky.

Keep the car on the 4x4 info screen and you can see the heights that all 4 sensors are reading, then when it faults look again and see if one of them has changed.

A friend of mine had an ABS reluctor ring on a driveshaft come loose so it thought one wheel was stationary. That lit the dash up like a Christmas tree with all the errors you mention but it didn't clear. An intermittent ABS sensor might clear though.
