Alfa Romeo – BCM, Body Computer and BSI comfort and body modules
In this category you will find comfort and body control modules for Alfa Romeo vehicles, including BCM, Body Computer units and selected control modules responsible for vehicle electronics. These modules manage functions such as central locking, lighting, electric windows, CAN communication, power supply to other control units and various comfort features in the vehicle.
We offer tested body control modules for popular Alfa Romeo models, including Alfa Romeo 147, 156, 159, Giulietta, MiTo, Brera, Spider and GT. Depending on the vehicle version, different types of body modules may be fitted, most commonly Magneti Marelli Body Computer units or other BCM modules used in the Fiat / Alfa Romeo group.
How to choose the correct BCM / Body Computer module for Alfa Romeo?
The most important thing is the part number from the label of the original module. When choosing a replacement, you should not rely only on the car model, year of production or the appearance of the housing. In Alfa Romeo vehicles, the same model may have different versions of the body module depending on equipment, engine version, wiring system and market specification.
Before purchasing, compare the numbers from the label, such as the OEM number, Magneti Marelli manufacturer number, Body Computer / BCM marking and hardware version. If you are not sure which module is correct, send us a photo of the label from your old control unit – we will help you choose the right part.
Common symptoms of a faulty Alfa Romeo body control module
