Ok so, I've had my ford focus 56 plate 1.8TDCI for about 2 months now and on 2 occasions I've broken down. The first time.........
I was doing a longish journey of about 160 miles and with about 10 miles to go I hit a traffic jam. As soon as I slowed to a halt my car cut out and wouldn't re start. I was towed off the motorway by the RAC and when they stuck the jump cables on and turned it over for a short period it started and ran completely fine again. When it happened no lights came up on the dash.
The second time........
again almost exactly the same scenario except I was only doing about 55 miles this time and this is about 2 months later. It cut out on a slip road off the motorway as I stopped for traffic lights. Again no lights on the dash and when the RAC put jump cables on and turned it over for a while it started up fine again and running 100%. He hooked it up to the computer and it had a message saying "fuel rail system, low fuel pressure" Its currently in the garage and they can't find the fault. They said its possibly the fuel pump (£529 to fix) or the fuel regulator valve (£198 to fix) But they said there's still a chance its not even that???
I have asked them to change the fuel filter and open that up to see the condition of it (read that in a forum somewhere) As this is a lot cheaper than the other stuff.
if anyone can help you would be a bit of a hero :)
I appreciate any input.
