Went to work the other day and on the way my Multi-function display started showing an overheat condition, however that was not the case. The gauge always reads (I believe) lower that is should read. It never goes higher than 1/4 over from cold. Is this the water temp sender switch?

I just fixed an overheat warning that would come on regardless. It was the tempature sensor, it also disabled my A/C due to thinking the engine was overheating. Cost me $250 parts & labor.

It is showing the overheat warning, however the gauge is normal, actually a little cooler than normal. Does that water temp sender also control the gauge on the dash?

does your AC work?

I beleave the water temp sender and the tempature sensor are different. Thus why you have a warning, yet a low reading on your gauge.

Probably need to replace the temp sensor

Do you know where they are so I can locate them?? I will have to check the AC

You have a Bentley? They are near rear of engine, both sides.I don't remember which is which now.

IAC valve to get to it. The driver side rear sensor in the coolant pipe is the engine coolant temperature sensor.
