Where is the thermostat gauge on the e60? I know they have on the m5 on the cluster how about the non m????
Or will it just pop on the idrive that car is overheating???

I dont think non m have a thermostat on our cluster but im sure we get the idrive warning message

Actually it does!!! Notice does little small lines on your rpm right next to 7,8 spending on how far yours go.. Pretty sure that does little lines is the gauge.. Go check out yours when you have your engine running... Normal driving you should have at least 3 to 4 lines
Keep me posted

i think those line gauge is a whackass temp gauge where it heats up to a point then when it overheat it will throw a error on the idrive.

OP, did you replace the sensors when you replaced the pump and thermostat. Not very familiar with the parts for the 6 cylinders but assuming the parts are similar, I replaced 2 sensors when I replaced the pump and thermostat. One on the thermostat and the other on the end of one of the hose connecting to the radiator.

Also, have you accessed the secret menu to see what the operating temp is when you get the message.

I do agree with you about those red line gauges. I do not trust them since mine is always on 4 marks no matter what the condition is.

I think the over heating message has 2 warning stages. One is engine is heating up and the other is to turn off engine immediately. This info was posted in another thread by Balbs, I think, in another thread about overheating issue.
