What is a Skoda Octavia Combi Mk4 airbag control unit?
The Skoda Octavia Combi Mk4 airbag control unit is your vehicle's central safety unit, precisely activating all occupant restraint systems, such as airbags and seatbelt pretensioners, in the event of an accident. It monitors sensor data, stores crash information, and ensures correct deployment to maximize occupant safety.
This safety-relevant module, often referred to as the airbag ECU, receives signals from impact sensors that detect the severity and direction of an accident.
Based on this information, the control unit decides in milliseconds which airbags should be deployed and when seatbelt pretensioners should be activated. It is closely integrated with other vehicle systems such as ABS and ESP to ensure a holistic safety function.

Typical signs of a defective control unit are a permanently lit airbag warning light or error messages in the on-board computer.
