Ford Focus 1.8 Tdci Sport S - 07 Reg - Engine Systems Fault

27 January 2013 - 10:09 PM

I recently bought a Ford Focus 1.8 TDCI Sport S (2007/07) after many happy years of driving a 1.8 TDDI Ghia until the fuel pump ECU failed.

Anyway, 2 weeks ago I got into the car and it started, sounded "lumpy" then stalled and then refused to start. It turned over but would not start and the lights came on etc (lots of stuff that flattened the battery) and then a "Engine Systems Fault" message appeared along with a red light on the right of the display.

I called the AA and they got it to start by forcing fuel through but it would not keep running and there were no error codes stored. Some more trying and the diagnostics then said "low fuel pressure". I then got towed to the garage where I bought it who then apparently took it to the local Ford dealership who got it running and said it was the immobiliser. Specifically that it was the key pick up at fault and I needed a new instrument unit. Being as I really had no choice I agreed and had it replaced and it took 2 weeks to get this sorted.

I got it back yesterday and was assured that the fault was fixed and it was definitely going to be OK. I took it for a spin and noticed that the acceleration was different, it was much quicker and less lagged. Not having had this model before I did not really notice there was anything wrong but the comparison tells me that there was. Having read other posts on "Engine System Faults" this seems to imply there was potentially an underlying fault when I got it.

So I got in it tonight (not having used it today) to go and get some fuel but guess what? ... you guessed it ... same fault!!

Has anyone got any ideas? I am only glad I was at home when it went wrong!!

Another point is that the car is parked on the drive with the engine "up hill" from the tank. The AA man said that their is a fault on Transit Vans where a small pin hole appears in the fuel pipe that feeds the fuel pump from the filter and so syphons out the fuel from the filter back into the tank. Anyone come across this before? Not sure why this would cause "Engine Systems Fault" unless it was too clever for its own good!!

Any thoughts?
