What is the spanner warning light which comes on and off on your vauxhall vectra 1.8 b?

The spanner warning light on a Vauxhall Vectra 1.8 B typically indicates a fault in the vehicle's engine management system. It can signal issues such as problems with sensors, the throttle system, or other engine components. If the light comes on and off intermittently, it may suggest a minor issue, but it's advisable to have the vehicle diagnosed with an OBD-II scanner to identify the exact cause. Ignoring the warning could lead to more significant problems, so it's best to address it promptly.
