Hi, I recently got a 2nd hand Ford Galaxy 2008 TDCi in November last year, with 79,000 miles on it which is now 84,000 miles. A couple of days ago the car was cutting out, and stops, then later it was going completely fine, maybe too hot, as when I checked the coolant level, its very low. But even when I top it up, soon after it is again very low. We are just waiting for it to be seen again by the mechanic. Has anyone else ever had these problems with a car before?
