What’s wrong
Due to the programming of the HVAC control ECU software under certain conditions such as a specific failure mode of the electric compressor the HVAC system will enter a failsafe mode that suspends the heater operation of the system and affects defroster function. In some cases when the vehicle is operated in certain low temperatures the defrosting performance reduces and may not remove frost ice and/or fog from the windshield glass. This can reduce driver visibility and increase the risk of a crash in certain driving conditions
The fix
Update the HVAC control ECU software.

How to check your vehicle
Use the official DVSA checker with your registration number to see if your exact vehicle is included. If it is, the manufacturer should have written to the registered keeper. The repair is free, even if you bought the vehicle second-hand.
