The airbag technology used in the BMW 4 Series varies depending on the year and model. Airbag24 professionally repairs control units for all BMW 4 Series generations with original functionality and a 2-year warranty.
The BMW 4 Series, introduced in 2013, has evolved over two major generations. With each generation, safety standards and thus the complexity of the airbag systems and their control units have evolved. This applies to both the physical design and the software.
For first-generation models (F32, F33, F36), defects in airbag control units requiring professional repair are not uncommon. These can be caused by aging, moisture, or other electronic problems. A professional repair of the airbag control unit is essential for restoring vehicle safety.
The newer second-generation models (G22, G23, G26) feature even more comprehensive airbag systems, requiring even more precise diagnosis and repair should a defect occur. Regardless of the model year, it is important to consider the specific requirements of each control unit to ensure reliable functionality.
The BMW 4 Series has been produced in two generations, each using different airbag control units. The development of the safety system reflects technological advances from 2013 to the present.
The first generation of the BMW 4 Series, internally known as the F platform, was launched in October 2013. This includes the F32 Coupé, the F33 Convertible (since March 2014), and the F36 Gran Coupé (also since 2014). These models received a facelift in 2017, which brought minor technical adjustments but retained the basic airbag architecture.
The current, second-generation BMW 4 Series is based on the G platform and was introduced around 2020. This includes the G22 Coupé (from 2020), the G23 Convertible (also from 2020), and the G26 Gran Coupé (from 2021). Each of these generations uses specific airbag control units tailored to the respective vehicle architecture and installed airbag systems.
The ongoing development of the BMW 4 Series from the F to the G platform also means an evolution in its electronic systems. A first-generation airbag control unit is therefore not compatible with a second-generation vehicle. For a successful repair, precise knowledge of the respective generation is crucial.

BMW 4 Series airbag control units can be uniquely identified by part number, model year, and vehicle identification number (VIN). Each generation, and often different trim levels, use specific control unit variants for optimal compatibility.
The part number is the most important indicator for identifying your airbag control unit. This number is printed directly on the control unit and should match the number of the unit being repaired or replaced. Sometimes there are also additional reference numbers that indicate specific hardware or software versions.
The model year of your BMW 4 Series provides an initial indication of the relevant generation (F3x or G2x) and the associated control unit variants. The vehicle identification number (VIN) is also crucial, as it contains detailed information about the original equipment and the exact model year. The VIN allows the BMW system to identify the exact components.
Even if an airbag control unit is defective, the part number is usually still legible. If this is not the case, qualified workshops or specialized repair services can determine the correct part number using the VIN and year of manufacture to perform the correct airbag control unit repair.
The airbag configuration of the BMW 4 Series varies depending on the model year, trim level, and model variant (Coupé, Convertible, Gran Coupé). While early models use basic airbag systems, newer generations feature enhanced safety packages with additional airbag modules and sensors.
All BMW 4 Series models, both the first generation (F32, F33, F36) and the second generation (G22, G23, G26), come standard with a comprehensive suite of airbags. These typically include front airbags for the driver and front passenger, as well as side airbags that provide additional protection in the event of a collision.
In the first-generation models, produced from 2013 to 2020, head airbags for the front passengers (curtain airbags) and, depending on the trim level, knee airbags were often available in addition to the standard airbags. The safety equipment corresponded to the high standards of the mid-range segment at that time, with a focus on sporty driving dynamics.
With the introduction of the second generation (G22, G23, G26) starting in 2020, the airbag equipment became even more comprehensive and technologically advanced. These newer models generally offer extended head airbag systems, knee airbags, and other options that are part of the modern safety concept. The G26 Gran Coupé, in particular, offers comprehensive protection for all occupants as a four-door model.
A defective airbag control unit can impair the function of all of these components. A professional BMW 4 Series airbag control unit repair ensures that the entire system functions properly again and the occupants are optimally protected in the event of an accident.
