What is a Volkswagen Tiguan BW2 airbag control unit?
The Volkswagen Tiguan BW2 airbag control unit is the central safety unit that activates all occupant restraint systems, such as airbags and seatbelt pretensioners, in the event of an accident. It continuously monitors all associated sensors, stores relevant crash data, and is crucial for the proper functioning of the entire vehicle restraint system.
This electronic module, often referred to as the SRS computer, is located safely inside the vehicle and communicates with other vehicle systems via the CAN bus.
It is responsible for detecting impact events and decides in milliseconds whether to activate the passive safety elements in order to optimally protect the occupants.

A Volkswagen Tiguan BW2 airbag control unit often becomes defective because it irreversibly stores crash data after an accident that needs to be erased, or because internal electronic components fail, leading to communication errors and requiring a Volkswagen Tiguan BW2 airbag control unit repair.
A failure can be indicated by an illuminated airbag warning light or by the control unit no longer being recognized by the diagnostic system.
Especially after collisions, the crash data record stored in the control unit blocks further function and must be properly deleted or the control unit replaced in order to restore full safety.
