HDi Running Temperature

[C.A.R.]

That's for VAG cars Chris, not cheap old Peugeots. Or Vectra's if you were interested, I'd prefer that it sat it 90 like the Mk4s used to, regardless of the actual temp.

It's a lot of modern cars unfortunately

It's to stop people getting into a blind panic when the needle goes a bit higher than they are used to. My Celica had it (albeit in digital form) and the MX5 had it too (from 1994!)

Poodle says it's linear, I'm inclined to subscribe to that since it seemed to wander in traffic this summer...
