Is the Airbag light or SRS on a mot failure?

Can your car pass its mot with the airbag light or SRS on?


Yes it will fail! If your airbag light is on or your SRS supplementary restraint system warning lamp is on it will fail its MOT. It comes under section 7.1.5 and 7.1.6 in the manual and is a Major failure. You can also try to reset the airbag or SRS light which may resolve the problem.

What the DVSA MOT manual states is the following.

7.1.5. Airbags

This inspection is for all airbags fitted as original equipment other than on Class 3 vehicles.

A passenger airbag that is switched off is not a defect.

(a) An airbag fitted as original equipment obviously missingMajor
(b) Not in use 
(c) An airbag obviously inoperativeMajor

7.1.6. Supplementary restraint system (SRS)

(a) An SRS malfunction indicator lamp (MIL) indicates a system malfunctionMajor

What is an Airbag or SRS light and how to fix it?

An airbag light or SRS supplementary restraint system warning lamp is the cars way of warning you there is a fault with the safety of your car. It could be an airbag faulty, switch or sensor. Its difficult to tell what it is without scanning your car using an OBD2 scanner.

The warning light could be a simple easy fix. Common airbag fault is when you push the front seat back and it moves the connector and just needs to be reset. See below on how to reset the light.
