This is quite easy,the filter is situated just by the left hand front strut housing 3 fuel pipes to clip off.Be careful not to break them this is easy to do them lift out the filter which cost around £30 from a main dealer.Dont bother with an after market one its not worth it.Ihope this helps

Also try changing the fuel filter .I did this and the car is running better than ever with no faults apparent.its gotta be worth a try:)

What you describe is the same what happened to my car.IT has to be worth changing the crank and cam sensors total cost about £40 diy fit is not too difficult the cam sensor is located at front of the engine by the glow plugs and the crank sensor is at the rear of the engine where the gearbox meets the flywheel i hope this helps keep us posted..............

Hi just an update on my cars problem.I changed the cam position sensor and also the crank position sensor and BINGO she is flying again and it cost £14 for the cam sensor and £24 for the crank sensor took about 30 mins to fit both of them where as ford want over £200 to do the job. i am well :) thought i was gonna be in for a whopping big bill gotta be worth a shot.I also replaced the glow plugs £11 each and starting is a breeze now i love my mondeo again HOOOOOOORAY.....

Hello all this is my first post i drive a 2003 mondeo tdci 115 ps with 104,000 on the clock and a full service history.I had a problem with the glow plug flashing and loss of power.I switched off the engine and restarted and it ran smoothly.The problem has returned it is so bad it does it nearly all the time ie start off with good power get to betwwen 2000 and 3000 rpm and then the glow plug light comes on and loss of power:mad: but keeps going although not at full power.On several occasions the power has dropped and the engine has died all together.I turn it off and on again then drive for another mile:-x then its gone again.It was suggested i change the cam position sensor which i did at a cost of £14:) this hasnt seemed to cure it.Any suggestions before i book it in to my main dealer for a pricey diagnosis.Thanks in advance "pistol"
