I have a 2001 Freelander TD4, it has done 190,000km. I have an intermittent problem: Every now and then the car does not start, it turns over ok but does not fire up, Usually after five or ten minutes it starts. It was suggested that the fault might be the fuel filter which I have replaced. I thought this had cured the problem, but after a couple of weeks the same problem was recurring. Anyone got any suggestions???
