normal operating temperature?

my owners manual doesnt give a number it just says it may rise into the red zone during hot days. so mine fluctuates between 88 and 97 celsius. is that typical for this car?

The gauge on my E55 isn't accurate... mine doesn't go over 100 Celsius on the gauge. However when I check using the cars built in diagnostic, it reads much higher.

To access the diagnostic readout... Press and hold the REST button until a readout appears, using the AUTO buttons toggle to 6. It should give you a readout in Fahrenheit. The highest I've seen is 220 Farenheit. I'm usually at 184-200 cruising...

Interested in what other E55s readout...
