Whilst driving up to Nottingham & about 1 hour into the journey a warning light came on & stayed on throughout the duration of the journey there & back which is approx 6 hour journey in total. The car did not miss a beat at all & drove fine. I have since found out that the warning light in question is the Exhaust gas monitor warning light & according to the manual it could cause serious damage if you continue to drive the car. Has anyone had this problem aswell & was it expensive? Any advice welcome.
