Thread: History of the LR TD5 engine?

Yes. The engine that started life as the 2.0l diesel for the Series 1 in 1955 or thereabouts was progressively modified and developed, with its ultimate expression being the 300Tdi. By the mid nineties, the basic design was forty years old, and there was no feasible way of meeting the next tranche of Euro emissions. So a completely new suite of engines was developed, 4, 5, 6 cylinders with largely interchangeable parts. Then the company was sold to BMW, and the only engine ready to go was the 5 cylinder, which would be the direct replacement for the 300Tdi. BMW did not quite have a direct replacement ready, and so allowed it to continue, but canned further development.

By the time Tata took over the company, and it regained autonomy, the Td5 engine was already outdated, and a completely new design for a whole range of engines - the Ingenium - started development. The Ford engine had been bought in to avoid attempting to upgrade the Td5, which had had all development stopped.

All a bit sad really. I like the TD5. But Euro 6 would have been difficult, to say the least.

TD5 engine - origins?

This is what I had found sometime time ago - TD5 the links to other pages are interesting too....

The Ingenium being a Jaguar Land Rover developed engine. mI'm still waiting for the 4L V8!

Reading these articles, I did not know about the different throttle maps for high and low range. I thought the TD5 had become sluggish in Low range, as I had to put the ight foot down so much more!!

In high range the you get a high percentage of power to a low percentage of throttle travel.

In low range you have a high percentage of throttle travel to a low percentage of power. This has been done to make it more controllable offroad.

One thing that I found several years ago and was flamed for is that the ECU maps etc were developed by Volvo.

If you run a text program through the standard map every file has a Volvo disclaimer not to change the file.
The suffix used on all the files is also a Ford suffix .vbf unlike the .Map etc used by tuners.
This is a Wordpad opening of the first file of the ECU maps.
I r

einforced this just recently as I supplied a standard map to another member .

vbf_version = 2.0;
header {

network = CAN_HS;

That might be a result of Land Rover being a part of PAG (Ford) at the time your car was built and an EU3 engine?

I highly doubt they had anything to do with initial development when LR was owned by BAe and then put into production by BMW.
