THIS 70mph THING .

god cant ya whisper any quieter????? o btw :welcome2: to LZ

Just burn the fooker and be done with it!!

Hi. I had same problem with my td4 when i first got it, cleaned the air flow sensor and it sorted the problem, you can get the air flow cleaner off the net or use an electrical conntact cleaner, I would also try new turbo pipes if not alreadey done so and blank the erg valve off, easey job and makes a big difference to the power.

thanks for that, will clean that today

Has a engine management fault code 'read' been performed. Should be the first thing to do?

yes nothing logged

Landrover have issued a service bulletin about a corrosion problem with the plug for the fuel pressure regulator on the td4 that causes a misfire or loss of power especially under load as the cpu gets a false voltage signal which in turn shuts the fuel delivery down hence loss of power, you get no fault codes as the cpu thinks all is working ok. There is a modified plug and wiring for the fuel pressure regulator. The landrover part No is YMQ503320 and It’s a easy fit.

this sounds interesting.will look into it , about time LR found a solution to this problem everyone seems to have this fault but no one can say why or how its fixed and that includes LR .nice one thanks. jeff

Two different entities! Your first 'LR' is he manufacturer, the second is the individual dealer ( and possibly individual member of staff ) you have talked to!

well after trying just about everything else its got to be worth a go,sounds right for the problem BUT so did so many of the others that have been good enough to try to help.

Don’t know the history of what you have changed, the other sensor that could cause the problem is the MAP sensor, which LR call multi pressure manifold sensor (which normally gives a fault code). The turbo boost valve that you have had fit if normally reliable. One way to check the MAP is remove from the inlet manifold clean it with a contact cleaner and refit and see what the difference is as we have also had a few td4 with that fault as well

Ok will look at that to . what gets me in these days you would think the computer would pick these faults up . to replace them all i would not be able to buy beer for a year anyway thanks for that will let you know how i get on,jeff

There is still the need for human intervention, where there are no fault codes, and where they do exist, on a suitably equipped scanner then one looks at live data to find irregularities. To keep 'throwing' parts at it is 'so 1970's '. What I have just 'said' is pointless, when, the answer is updated engine management software, though most unlikely in this case.
