It could be a faulty sensor but normally when it goes it displays ludicrous temps.

On other VAG cars the sensor is behind the grill on the nearside so I assume that's where it's located on the Scirocco.

The MFD displays the frost symbol when the temp falls below 4 degrees.

External temperature sensor, part number: 8Z0820535

Same part used across all sciroccos, golfs and numerous others.
It's located behind the front lower grill, usually to the left side (passenger side)

-45c indicates pretty much open circuit.
