Hi there. I have a lovely 2013 Focus diesel Econetic. The stop start system has stopped working. I think there may have been a problem with it when I bought it (about two years ago now). On occasions the fan would kick in when I parked up sometimes even on short distances and it would run for about three or four minutes. The last time it happened, I had to wait (parked up) for five minutes before the fan stopped. I was worried as I had two dogs in the car as I thought it could have caught fire, so waited until the fan stopped. That incident only happened a few months ago so not in warm weather and I had travelled only about a quarter of a mile before parking. Since then, the stop/start has only worked once. I’m no mechanic but assume something must have burnt out (?). The car goes fine without it so should I be worried and/or get it fixed? It’s going for an MOT/service next week and I will ask them to look at it but would like independent advice beforehand as, like I said, I’m no mechanic and don’t want to be ripped off. Can anybody advise?
