W211 E500 Temp Gauge High Read Solved
we live in a hot place but my 2004 e500 sport wagon has car temp on the dash board that is always 10 or 20 degrees higher than the outside temp, or any of our other car temps.
if its 90 or 95 degreees outside, my dash will read 105 and up most of the time.
I thought we were in an unusual heat wave, till my wife ratted it out, after we switched cars.
Also, I had the Jet Turbo helicopter sounding fan on most of the time, announcing my arrival from 2 1/2 blocks away.
solution:
I recommend mend waiting till the next morning before the car is driven, so that it will be cool to avoid it being Hot
step 2
Using the 8mm Socket and wrench, remove the 4 to 6 srews holding the smaller front plastic under cover from the car.
step 3:
look up and around behind the uppper bumper/lower grill
And look for a dangling sensor on a twister wire...
Fell out of the whole it belongs in and starts reading the heat from the engine compartment instead of the outside. And i think this contributes to the super ultra high fan power selection by the mb car system.
(I'm so sorry my car is dirty and that this dead fly bellow the sensor is now immortalized on line).
I used electrical tape to try and secure the plug in place
My car's temp now reads 86 degrees and the vehicle fan can just barely be heard. Neighbors and family no longer know i am arriving from two blocks away.
Aloha
