Finally got my mini back on the road and I noticed the other day when it was 28c i ended up getting pretty hot in a drive through (hit red on my gauge) so I've been reluctantly driving it on cooler days and today (about 24c) I was doing some highway driving and it was getting close to red when I took my exit and immediately upon slowing down the gauge dropped 1/4 of the way down very suddenly and stayed there for the most part until I stopped at my next location. The rest of the day it seemed to hover at about 3/4-5/6th of the gauge. Just curious on how reliable the gauge is in this cluster are normally since it seems to act a bit sporadic. It has a new thermostat i put in before winter last year.
