Noticed my coolant temperature gauge doesn't work on my new 325e. Is there an 'idiot' light that will turn on if it overheats, or will I be completely oblivious if it does? It runs excellently, but that's not the best indicator of engine temperature.
Is there a way to test the gauge before replacing the sensor?
I am planning on getting a Bentley but I need to drive around (to work mostly) and I'm not sure where the coolant temperature sensor even is.
Oh, and does the fan clutch work off of a different sensor? On my VW it has a separate one so even if the gauge sensor fails it will still turn the fan on. If the sensor is bad and it's the only sensor it's possible the fan will never go on, which obviously is bad.
