Hi everyone,
My 2003 TD5 diesel auto was recently given a 72k service by a non-LR specialist. Not long after - approximately 60 miles or so - the engine developed a misfire.
It was not immediately apparent at the time. The car starts on the turn of the key and runs fine, but after around 2-3 miles the misfire starts. It feels as though it is not firing on one of the cylinders and consequently at certain speeds 55/60 MPH causes a tremendous vibration throught the car. If it is left for acouple of hours, the cycle starts again i.e runs fine for 2-3 miles, then continously misfires.
My wife took the vehicle back to the garage, typically it was running ok at the time- but a new fuel filter was fitted. This did not cure the problem and so it went back again. The mechanic plugged it in to his diagnostic machine and no fault codes were present. He doesn't know. To this end, he has booked the car in to a diesel specialists this week for a diagnostic check on their systems.
After reserching this forum, I have checked the wiring harness to the ECU and this is dry and clear of any oil residue.
I am wondering, is the misfire, the car actually going in to limp mode for someother reason ?
Are there any issues with non OE fuel filters ?
Any help would be greatly appreciated
Regards
RDW
