:L - I've been reading the many posts on this site with reference to faulty injectors as my mondeo 02 55k 130 tdci has suffered many of the similar faults: My local Ford dealer is baffled by their on going failure - so far they do not know what underlying problem is causing the problems (limp home mode, flashing glow plug light, smoke etc) -Then it dawned on me - the car has gone too long without a fuel filter change - since replacing it - the problem is solved - so far - car runs well

Ford service schedule states to change the fuel filter at 37.5k miles and draining the filter to check for water every 12.5k miles (which I doubt gets done every time). Over in the USA many diesel specialists recommend changing the fuel filter every 5k to 6k, which sounds like a more sensible approach to me on a very contamination sensitive system like modern common rail diesels have. Mine's done nearly 18k now on the original filter and I'm contemplating having it changed. (Or am I being a bit paranoid ?) :ponder:
BTW Forgot to say, I only use Shell Diesel extra in mine (with a bit of Millers for extra lubricity).

I think you're spot on wanting to chabge he filter early. My tdci is due it's 3rd service in feb. It's only done 25k miles but I'm going to have mine changed and maybe do it every 5-10k miles. How much do the filters cost for these cars?

What gets done at the third service? Is it every 12k?

Your being paranoid!

Follow the Ford recomendations for changing filters as they have already done the maths and have already designed some safety margin into this replacement frequency.

The reason that this time is shorten in the US is because deisel is not as common or well used over there. The quality of it is very much reduced compared to ours. It also contains a lot more water.

[quote name=kithmo]draining the filter to check for water every 12.5k miles (which I doubt gets done every time

Is it just a matter of pouring out the fuel etc from the filter and checking for water in it? How can you tell etc?

According to Haynes, you have to remove the filter, then unscrew the knob on the bottom and drain some fuel out into a glass jar. The knob has a pipe on it and I guess you could do it with the filter in place if you attach a flexi pipe and run it down the back of the engine to a jar under the car, a bit fiddly, but it's not possible to fit a jar directly under the filter because the alternator is in the way. Make sure you don't spill any diesel on the alternator. This is why I don't think it would always get done, cos it's fiddly.

:BEEP: hello, if you would have suffered over £500.00 of repairs to injectors, you too would be paranoid! - The new filter fitted in my mondeo has changed the way my car goes (for the better) and the injector faults have dissapeared:

i dont trust any of fords figures and durations specially where servicing goes i mean look at the old 1.8 td cambelt every 70k ford say but then people have had them fail well before that also what jezza said on another thread changing a fuel filter solved his probs with his tdci yet he had forked out over £1200 before hand that was down to ford!!! oil change for tddi and tdci is 10 or 12k i think? i wont be doing that il lbe doing mine every 6k i used to do every 3k on my old car but it had a lot more miles on it and end of the day changing fuel and oil and air filters early is better than waiting twice as long or whatever and ending up thats what caused the problem in the first pace. i have never trusted any of these service intervals and theres plenty of proof on the forum to back me up.

this isnt a personal gripe mate im just saying, if you want to service yours when the intervals are ford says then fine its your car and your money no ones going o stop you but, i see it as prevention is better than the cure after it can end up costing you more in the long run or you end up selling your car because its costing to omuch and could have been prevented and the car would have cost you less overall.
