Right guys, UPDATE:

The Ford garage has had my Ford Focus Titanium for 7 days today. They rang me to say the car was ready. I asked what they had found. Answer: "NOTHING"
I told the service manager what you guys had told me and he said that was a fault on older models and I have the 2016 model which has no faults.
All they had done apparently was to give the battery a boost for 2 hours this morning. I brought it home but am seething.
Question: On the speedometer on the right is a vertical line. Is that telling me the state of the battery? If so the needle was at the top when I picked the car up but when I got home it was mid way down. I'm just wondering what that does.
I'm pretty sure it will break down again soon as it has done every week or so.
