Cause : Air intake overtemperature comes when threshold for the air intake overtemperature has been reached. For air-cooled power units, the threshold is 42 °C (hysteresis 2 K). The response is set using p0290.

If the air intake temperature increases by an additional 13 K, then fault F30035 is output.

- is the ambient temperature within the defined limit values?
- has the fan failed? Check the direction of rotation
