I was browing my Startek DVD looking for some information as to why my Coolant Guage in the instrument cluster and the Temp readout in the HVAC controls were different. Heres what I found regarding the ECT Guage

" This display (guage) is a plateau display. i.e. the pointer stops at 95 degrees C. at temps between 95 and 115 degrees C. Temperatures in this range are still not critical. The correct temp is only displayed again from a temp. of 116 degrees C. This prevents the driver from being disturbed by the display, for example at high outside temperatures. The warning rage starts at 116 degrees C. The coolant temp signal comes from the engine control module."


I know my Passat was that way but I thought the MB was an actual reading. I guess I have to be "disturbed" by watching the HVAC module with the temps. incrementing from 88 to 105 depending on speed, ambient temp., and how long the hill climbs are.
