So I'm driving a few weeks ago fairly spiritedly for abt 5 min. I get off the highway and I get the "engine overheated" msg. I pull over and notice I do not hear the auxiliary fan that is associated with a hot car. Let the car sit turn it back on, no msg and still no fan. Weird to me so I then drive hard to see if the fan cuts on it does and no overheating msg. New radiator just installed Car wasn't low on coolant and I had my cooling system done earlier this year(water pump thermostat). Further more i put my car up to a GT1 and showing no errors. Any idea what this could be? When I pulled up the hidden temperature menu the temp ranged from 85 celcius(on start up) to 110(after a spirited drive) Someone mentioned an "oil level sensor" sending false codes to the DME. Any help is appreciated as I am baffled...
