Umm, it's not a gauge? seems like it haha!

it's always in the vertical position without flutcuating, even in hot weather and slow traffic.

I'll put the scanner in the car and will have a look at the water temperatures during a ride to see if there's anything strange happening that would kick off the P0115.

Yesterday I guess I hit some diesel on a roundabout... nice controlled 4-wheel drift to the outside (to stay on topic :P )
