0 frogland Posted July 6, 2018 Report Share Posted July 6, 2018 (edited) This question interests me. I've also got the check engine light,due to a boost code but I can live with it and the car still runs. What if i were to remove the bulb or black-out the light on the cluster ?? Would it pass the MOT ? Edited July 6, 2018 by frogland Quote Link to comment Share on other sites More sharing options...
0 dave62pb Posted July 7, 2018 Author Report Share Posted July 7, 2018 The law now states the light must show when ignition on and go out when running , Mad because the car runs fine and passed on emission test the fault could be anything Will keep posted Quote Link to comment Share on other sites More sharing options...
0 frogland Posted July 7, 2018 Report Share Posted July 7, 2018 Ok I suspected as much. Mine runs fine as well. I'll have to enquire as to whether the same applies in France;that's where I live. Quote Link to comment Share on other sites More sharing options...
