I know this has cropped up before so apologies if I'm treading old ground.
as you can see my engine warning light came on last night, no loss of power, running, idling same as always. This happened a few years ago, somewhere I read (maybe on here) that if you switch the ignition on and off three times and then give it some welly on a good stretch of road it resets and goes off. This actually worked, but not this time. I'm having a new Dobbie and p/x this one in a few weeks time so don't want to be forking out much. Wondering whats the best course of action, I'd welcome any ones thoughts.
