The warning light has two states. A blinking light indicates a critical problem with gaseous emissions from the engine that is likely to cause permenant damage to the engine, exhaust sytem or catalytic converter. A blinking light must be remedied immediately, and the car should not be driven in this state, at the risk of causing serious and permenant damage to the engine, exhaust and/or catalytic converter. Repairing or replacing these parts can be extremely expensive. A reputable garage or a Vauxall/Opel garage should be able to diagnose and repair the problem.

A solid (unblinking) light indicates a non-critical fault in the emmisions exhaust system. Many faults are covered by this light including failures in emssions sensors, temperature sensors and a variety of other parts. This usually results in a higher than average amount of environmentally harmful pollutants being expelled from the car, loss of power and/or gradual damage to the engine, exhaust and catalytic converter. While the car can still be driven with a non-critical emmisions problem, it is highly recommended that the fault is diagnosed and repaired at a reputable garage or Vauxhall/Opel garage.
