Mmmmmmmm just reread the manual and can’t find the reference to it. So maybe a figment of my imagination ?


BUT I recall reading that the valve closed as speed / Revs increased?

I suppose the only thing remaining for me to do is to disable (setting adjustment) the ECU trying to adjust the EGR. Some one in a previous post said this could be done via a nanacom?

I just took a look at a Nanocom file in the graphic viewer from before the EGR was removed (EU3 Td5).

The EGR & wastegate both mirror one another when the turbo is boosting med' to high pressures ... very slight EGR activity for overrun.
They both show a MAX figure of 40.

I haven't done another Nanocom run since the EGR has been removed to compare.

I removed everything I could. By removing the heat-exchanger I was able to use standard LR parts and re-plumb the coolant back to the radiator. This is a fair bit more work as it requires the radiator to be removed and the unused spigot on the radiator (lower rear driver side) to be tapped. Standard LR pipe then just connects up.

But the hose for the cooler comes from the block, goes thru the cooler and then into the bottom of the overflow bottle....
I broke the plastic tube from the cooler to the overflow while doing something else a few weeks ago. Luckily had some 5/16 heater hose on hand and just ran a new line from the cooler back to the bottle. When the EGR gets done in a few weeks, cooler will be coming out and just run a new one piece line between.

The coolant on the TD5 with the EGR cooler comes off the oil cooler, small length of hose joining a metal pile that goes around the back of the motor then down the drivers side extending just past/near the fuel cooler.

A hose then takes coolant to the inlet side of the EGR cooler. It exits the EGR cooler and returns to the *four way connector just below the coolant reservoir.

This *four way connector connects the heater hose, the reservoir, the EGR cooler and the fuel cooler. Note the four way connector caters for different hose diameters.

If you remove the EGR cooler you can then use the coolant plumbing from the previous models that didn’t rum the EGR cooler.

Your coolant then flows

From the oil cooler via the small hose into the metal pipe as above. Then instead of going to the EGR cooler it goes down to the bottom engine side of the radiator where there is an untapped spigot.

You need to tap (open the spigot - drill out the plug) and connect the original equipment hose from the previous model. Note on the chasse there are 3 hose clamps one of which is not used. It is now.

This leaves the EGR coolant return line to the reservoir to be either caped off or use the three way connector from the previous model and hoses.

Since I was replacing all my coolant hoses I opted to use the previous model hoses and three way connector.

To my delight while doing this I found that the three way connector has all the same outside diameters. So the coolant line from the heater and the fuel cooler which have a smaller inside diameter at the four way connector now have a common diameter.

When all finished all the little hoses for the EGR and modules are gone. Using the previous modes coolant lines removes about five or more joins. And the coolant hoses run a common diameter.

I’ll try and take some pic’s over the weekend.

Pics of mine. Cooler first

Reservoir connection in 3/8 hose. This replaced the hard plastic line that fractured. No multiple spigot tapping point.
Feed comes off oil cooler but there are no other feeds from this steel line at all.
Maybe different fitments???? Mine is a D2a.

Is this LR's "TD5 EGR removal pipe" ! ? :

Whilst looking at original LR parts to remove the EGR, does this part look like a direct straight through replacement for the ERG valve: ?

See: Microcat > Engine TD5 > Mainifold Inlet >

Part number LKX000020

I called my local dealer who said the part would have to come from the UK, so no idea on cost, compared with the aftermarket alternatives.
