I'll give it a try.. Thanks for the info! Also how long did it take to come back up to temp? Any chance you have that info?
During my drive today I watched the temp the whole time. It took about 16 minutes to go from 16C to 21C in 1C increments then all of a sudden it jumped from 21C to 27C. Now that I think about it I think there is some delay in these temp sensors as I remember even the stock temp readout on the heater controls of my 200 series took a long time to go back to the normal ambient temp reading after a short river crossing which made the temp readout drop
