Hi all,
Have been having the amber engine light flashing on/off on my 04 TD4, for a few months,
It will flash under heavy acceleration or when going up certain hills under load and when rev's are about 2000rpm.
I've had it to a garage for diagnostic check which found "4 unspecified error's" but nothing that they could read. They wiped the memory and took £50 for the privilege.
I've plugged an obd reader into it and that has come up with no codes either as it has started to flash again.
The car has 73,394 miles. Full service history with the last service done with a full 72k genuine LR service kit, had air, oil, fuel, crank, and pollon filters changed.
The cars been remapped but that has been on the car for 3 years with no issues. The EGR has been blanked for the same amount of time.
The car is down on power at all rev's, it struggles above 60mph at times to gain speed. There's an increase of black smoke under load and the MOT smoke/emissions were higher this time than last time.
I had an injector test done 3 years ago to figure out why it would have blue smoke on start up, this showed that injector 2 had less flow than the rest but the figures were all over the place.
I got a fuel pump changed when i bought the car with 37k on the clock, i can't mind what one it was as i know there are 2 in the system. The car wouldn't rev and 30 mph was a struggle to hit when that pump went.
Does anyone have any ideas as to what the hell is up with it, i really don't want to throw yet more money at diagnostic tests that throw up no codes.
I'm guessing for the lack of response and dip in power with the mot test smoke/emissions that it is a fuelling issue with a sensor/pump/injector.
I'm keeping the car for another 3 years minimum so would like to get it sorted properly.
