Happened to me yesterday after I filled up with 95 Octane from Shell on the M2 highway. Pulled off and drove for about 10 Kms and the light came on. Called Lyndhurst Auto explained what happened. I was told to pull over on the side of the road, switch the engine off and on again. Light disappeared. It might have been inferior fuel with particles that upset the catylyst converter I am being told. Now I'll be extra carefull where I fill up...
