Its the orange "Engine light for the exhaust emissions have deteriorated" warning light and has not failed any MOT's on it. The chap at the garage said that BMW's are a pain in the a*** for warning lights, and since it was just the fuel mixture light and no issues with the emissions since then not too worry about it too much, the original fault was code E3. As the emissions have all been fine since 11/08/10 I have just left it. It does reset but come back on after a few days, I did not want to get it reset again or as some would have done and take out the bulb, I am being honest about it. From what i understand new MOT is for dashboard warning lights that show a problem such as Airbags, Electric Power Steering, Electonic stability sytem and additional restraint systems; since this light is not related to restraint systems and all the relevant emissions tests are good it should not be a problem. It has had 2 MOT's since with no emission problems.
