D3 TDV6 poor fuel economy

Also, for egr valves.

If your car is an 04-07 it can be blanked easily. Plenty of kits and guides to show how to do it.

If it's a 07-09 then you need to fit emulators as well as the physical blanks as the egrs are tied into the engine management system and simply removing the egrs throws up an engine warning light.

The emulators fool the car into thinking the egrs are still present and doesn't throw up a warning light.



If it's an auto, it may need the gearbox oil and filter changed.

ZF say every 50-75,000 miles between changes for them.



Very few people do that of course.

Is there an emulator product without buying new EGRs? Thanks

I found the post. All good

The last service was 1,200 km ago. I will need to check at the workshop but it would seem the fuel filter was not done.

I have the blanks and have been trying to find the time to fit them.

Transmission service was done at 60,000 km (9,000 ago).

The MAF sensor sits just to the right of the air box as you look at it.

You mean the one referred to as 'MAP' in point 4 of the attached?

Yes, point 4 is wrong! That's the Mass Air Flow sensor, which has a delicate wire which must only be cleaned with MAF sensor cleaner.

:lol2:
If that's the official LR workshop manual, then that's a bit of a screw up.

Google part number LR019130 (or 1316126 the old number) for the MAP sensor, and you'll see the image and location.

Equally part number PHF500101 for the MAF.

And if you think about it, the best job and best place for a Manifold Absolute Pressure sensor, would be measuring Pressure (of the pressurised air being fed from the turbo) in the inlet Manifold? :angel:

Good old Land Rover, inconsistent at the best of times. :D

Yes was aware of that - just that LR didn't want me to find the sensor...

I did say that I did a search for 'MAF' in the workshop manual and it only gave me the petrol engined versions...

Of course the manual was bought from the forum store ;)
