I've had my 08 plate fiesta from new for 2 years now and only done 40,000 miles and on a recent service it was found that there was a hole in the Diesel Fuel pipe caused by where it is placed under the engine block and something else. also one of the mechanics that serviced my car had a look at his 58 plate Fiesta and it was srtarting to do the same.
so i thought i would post what has happend to let other diesel fiesta driver the possibility of it happening to you. and to see if it has happened to anyone else.
ford them selfs wont do anything about it as i got it done at a kwick-fit garage not with an authorised ford dealer. but looking into claiming something back some way or another.
