My Ford EcoSport cuts out...

I have a Ford EcoSport. The stop/start system, when I switch it off, at times, still makes the car judder a bit. When I've stopped, at traffic lights, then the engine switches off. I've not put it in neutral or took my foot off the clutch. This will only happen a few times, then the car runs fine, with the stop /start off. I don't understand why it still cuts off, when system is off?

Hi Debbie,

It doesn't sound to us as if this is anything to do with the stop-start system, but actually an issue with the engine itself that needs looking at by a good mechanic. You've not told us which generation of EcoSport you have, nor which engine it has, but the 1.5-litre TDCi diesel has a known issue with the turbocharger wastegate valve that could cause engine running issues. It might be worth mentioning to the mechanic when you bring it to be checked.

Best of luck
