OK, but the car did not give any fault code. I will check for possible fault via the clock spring wiring as suggested sir. Thank you awesomely.It can simply be due to a faulty brake switch, but it is best if you read the fault codes and see what the car thinks is faulty. Steering angle sensor faults are often not real faults, but the 'clockspring' wiring inside the 'Comm' stalk unit behind the steering wheel can eventually wear and break. The Airbag system has a number of parts, so start with the fault log.
My battery is just a year old.Battery condition is the single biggest issue for 206 airbag lights
