SJM1985, im in rotherham also and have just bought a focus 1.8tddi. i bought it as running poor. previous owner spent 100s on it, fuel pump,some sensors, etc, but its having trouble. it will start fine,no smoke but runs as if no turbo. though you can hear the turbo spool up ans the pipes expand some. it will rev to 4500 when stood but has no power when driving. i really would loike some help if possible im no stranger to engines. ie 2.5 rover engines but am a novice with the diesels.
