2.7 TDV6 - EGR Blanking

[101RRS]

My TDV6 EGR system is all serviceable and working as it should. I have read a lot about blanking off the EGRs and the benefits in long term reliabiity. I have read that if blanked - as long as the EGRs themselves are serviceable you will not get any errors when the blanks are on.

So has anyone put EGR blanks on their 2007 and later TDV6s and what are the pros and cons. Kits are cheap and easy to do yourself if required.

Knowing my luck if I do not put the blanks on I will get blocked EGRs when I am miles from anywhere and have a miserable drive home in limp mode.

Hi Garry,
2007 and newer D3s (and I suspect RRS) have the Euro IV engine. A consequence of this is that if the EGRs are blanked it throws an engine management fault. Currently, there is no workaround for this.

On this basis, the best that I can suggest is to carry some spare EGRs. :(

Best Wishes,
Peter

I have Garry,
My EGR valves on my 05 where working fine too but decided that it would not hurt fitting them for the same readon as you stated. I got the simple blank plates that you leave the existing pipework in place so from the outside it looks standard. You do need to remove the butterfly from the intake but that is pretty easy.

I read on the Uk forums that as long as the EGR itself is still serviceable the fault message does not occur even on later engines.

However I am always sceptical - hence my request for comments from people who have fitted them.

Maybe I need to amend my original post to specify 2007 and newer 2.7 TDV6s.

Thanks

Hey Rich,

Is it correct that blanking them off improves engine pick up? How does your D3 drive now compared to what it was like before you put the blanking plates in?

cheers,
Terry

To tell you the truth I could not feel any difference!
Although you definitely can tell when you remap the CPU :)

[101RRS]

The blanking plates are not to make the engine go better - it is to stop the EGR etc clogging and making the ECU having a dummy spit and going into go slow mode - and then having to spend money to fix them.

The downside is that because some of the exhaust gases are not being fed back into the inlet system, emissions increase.

Often when an EGR valve fails it stays partly open. This adversely affects performance but a blanked one will not. It will still fail in time if blanked beforehand unless blanked on the inlet side rather than the usual (easier access) outlet side. The 2007+ models show an annoying warning light in the instrument cluster when a valve fails. The light was added because failed valves (and there were many) weren't being detected by the driver and thus weren't being replaced. The criteria for a detecting a failed valve is that the mechanism doesn't move to where it should, as its posiiton is monitored. If I had a pre 2007 model and the valves were still operating correctly, I would just unplug the valve electrical connectors (with the engine stopped) and remove the throttle butterfly.

Im just wondering what the condition of the MAP sensor was before blanking the EGR ?

[Jamo]

I didn't bother with a kit on my 2005.

I opened the throttle body and removed the butterfly, then re-inserted the shaft that the butterfly is on. That way the system doesn't know anything's wrong (and neither do most LR techs).

I then crimped off the ends of the EGR pipes where they entered the throttle body.

No plates or pipe removal necessary.

The hardest thing was getting the butterfly valve shaft out.

None of this will stop eventual failure of the valves as they tend to corrode. I think the difference between the 205 and post 2007 is that the pre 2007 models threw up a MIL but there was not necessarily a corresponding limiting by the EMS. But I could be wrong.

[Graeme]

I can't fathom why there would be any EMS changes, as the valves are only opened on idle to quieten the diesel rattle (by delaying ignition in the reduced oxygen environment) and on light throttle cruising to reduce emisisons, as documented in the WSM. Its not as though they are opened whilst the engine is working hard.

[Jamo]

Well it can. But it's random apparently. Maybe a cascade causes it, I don't know. But some have had to replace EGR after blanking; although most haven't had a problem.

What I can't fathom is why LR put EGR valves into vehicles that are prone to corrosion1

where did you get your blanks Rich ?

thinking of doing this soon..

[Discofever]

Does anyone have a guide how to remove the egr, install blanks and remove butterfly valve from throttle?

Thanks in advance.

That's what I needed thanks mate.

[Catmatt]

Discofever....... Fitting the blanks is a substantial amount of work and should only be contemplated if you are a competent home mechanic. There is many things that can go wrong and the pipework can easily be damaged replacing everything after blanking.

A far easy alternate is to remove your ECU and send it away to both be remapped and have the EGR closure software installed (The software ensures the EGRs never open again and won't produce a fault code).

Benefit is better engine power and torque thanks to the remap and cleaner engine by having those useless EGRs permanently closed!

Works a treat on my D4 and I have had no issues since having the upgrade close to 2 years ago!

Hey Catmatt, liking the sound of your solution and wondering where you sent your ECU to and approximately how much the re-mapping cost?
thanks

I have a bunch of error codes related to the EGR and assuming I need new valves... but reading this wondering if anyone out there can do the blanking. I live in regional Vic (Bendigo area) but happy to travel to Melbourne etc if someone can do the job. I am female and no clue on anything mechanical just FYI lol
