bmw x5 e53 actual intake air temperatur error?

[Clavurion]

And the intake air temp sensor is implemented in MAF. I wouldn't rely on Carly regarding this information.

Have you checked coolant temps with diagnostics or from cluster hidden menu? Failing thermostats is one culprit on these. The running temp should be near 90 C (main thermostat is 88 C). Is your Webasto still working as it helps massively getting to running temp on cold climate.

so i need to change the entire MAF=?
the webasto is running non stop when engine is on.
engine is beeing cooled all the time since that actual intake air temperature is so high so the engine dont get hotter than 50-53
