BMW 5 Series: Introduction

General information

The new BMW 5 Series with the development code G30 will be equipped with a further developed and optimized heating and air conditioning system. The heating and air-conditioning system is similar to the BMW G12. The G30 uses the new R1234yf refrigerant.

A brushless blower motor is installed in the heating and air-conditioning housing which provides the supply of fresh air to the vehicle interior via the fresh air microfilters. The microfilters can be replaced from an access point from the footwell area under the dashboard on the passenger's side.

The IHKA control unit is separate from the IHKA control panel and is located behind the dashboard on the passenger side towards the center of the vehicle.
