Ford Focus 1.8 Tdci Sport S - 07 Reg - Engine Systems Fault
Posted 27 January 2013 - 10:09 PM
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!!

The key excuse is bunkum.

The 1.8 seems to have only one Achilles heel and it appears to be the fuel filter.
I had this myself a few months back and a major service cleared it right up.
You may well get fault codes referring to low fuel pressure and such like.

According to the dealer, the AA man damaged the seals on the fuel filter when he was trying to prime the system and so air was getting in thus draining the fuel lines. (Does the pump not self prime afterwards?)
I was also told that the "road side diagnostic tools" would not have picked up the fault code from the immobiliser so that (AHEM!) "still needed to be changed" ...
They have now "changed the seals" and are checking it starts reliably.
The true test will be when it is back on my drive.

Fuel filter then?

I would not say that a local garage is any worse than a main dealer as the main dealer changed the instrument panel on mine before they fixed the real issue with the fuel system having a small leak of air into the system so they clearly were in the dark too.
I have read other forums where the fuel filter was the cause of similar problems so it does not seem that uncommon and it was the first suggestion made above too ...

For any garage to say the filter doesn't usually need changing is total cobblers!
I had an engine system fault flash up on mine last year and error codes were stored concerning low fuel pressure.
Trust me when i say it was DEFINITELY the fuel filter.
I had mine changed on a full service and the problem was gone instantly.
The garage showed me the old filter and it was full of fuel tank gunk and detritis.
In my opinion any garage that doesn't change a fuel filter on a TDCI Ford is a bunch of feckless tools.

Cheers guys, you've definitely made me feel more confident that they're on the right track. Will report back when they've fixed it.
Please do, the only achilles heel on the 1.8 TDCI i've seen so far is that the fuel filter is partial to regular changes.

I'm thinking they've not fitted the filter correctly, is that a reasonable assumption and if so, would you expect the dealer responsible to now finish the job for free?

I'd definitely expect the garage to rectify their mess.
