Is it safe to drive with this code?

The vehicle typically remains driveable, but the passenger airbag may be disabled or may activate incorrectly, raising a genuine safety concern for any front-seat passenger; see our disclaimer for full guidance on restraint-system faults.

An illuminated airbag warning light is commonly considered a reason for MOT refusal; what matters is the lamp's state at the time of test—see our disclaimer for the legal position.

Roughly how much does it cost to fix?

Sensor mats themselves range from low to mid three-figure sums; labour for diagnosis and replacement adds another hour or two; independent garages often charge less than main dealers, and some manufacturers offer goodwill cover even outside warranty—a full sensor-and-mat job could be mid three-figure or creep into high three-figure territory depending on parts availability and workshop rates.

Can I simply clear the code to get through MOT?

Clearing the code may extinguish the warning lamp temporarily, but the fault will often return once the system performs its next self-test; a stable repair is needed to keep the light off and ensure the airbag functions as designed.
