I too have the same problem. My car gets to 76 degrees within 5 miles or so but has never gone any higher. When I put full demist on the gauge drops to quarter when the fan kicks in. I haven't checked OBD for temp with full demist on yet.

I have an egr bypass and in-line stat fitted.

Will be interesting to see the results of a sender change.

Might have to try the rad blocking technique.
