Just a quick update. I decided following good advice given here, to refit some EGR pipes. You may remember that my EGR valves had been blanked off by a previous owner, and the pipes totally removed. This made it blatently obvious that my valves were not woring, and you could see the blanking plates easily.
So my local D3 technicans sold me a secondhand set for a tenner, and I fitted them today, leaving the blanks in place obviously. Bit of a knuckle baring job, but they are on, and it looks "normal"1955 SWB Series 1 86 inch

In this particular instance EGR's are an electrically controlled, motor operated valve designed to recirculate a percentage of the exhaust gases back through the inlet manifold to be re-burnt.(reducing harmful gases) This causes no end of carbon deposits / contamination and clogging of the entire induction system. The EGR's themselves are by their design troublesome, as they are subject to the extremes of exhaust temperature as well as the same carbon contamination. Combine all that with the complexity of the their design inevitably leads to regular failure. Faults, MOT failures, costs of replacement, power loss, etc often forces owners to block the gases entering the inlet manifold by means of a blanking plate on each valve. Later vehicles (MY07) also require a software patch to prevent the engine management light becoming illuminated.
The benefits of blanking are to completely avoid the aforementioned issues, Sorry for the long winded version but I'm in rant mode yµ (idµ - eAµ) ψ=mψ

My Cousin has a 57 plate D3. Recently it has caused him no end of problems, limp mode, no acceleration, and more.
He had the EGR'sblanked, and the software updated, he is amazed, it's a different car.
So get it fixed at your convenience, before it catches you out at the EGR's convenience.1955 SWB Series 1 86 inch

Just to bump this thread again, my apologies..
I’m just confused about the >07 issues. Is the ECU flash just to turn off the dash light? Or does the >07 not drive nice without the flash?
If it’s just the light then I’ll just blank them off.Defender 110 2.4 TDCi Utility Station Wagon.

I think I'm right in saying that on MY07 onwards failed EGR's put the engine management light on the dash. This is an automatic MOT fail. The patch simply switches off the light for the purposes of EGR failure.
So you can either fit new EGR or blank and patch.2006 D3 HSE Buckingham Blue

Brilliant- thanks for the reply. So what your saying is that blanking the EGR’s will not affect the drivability, but just put the dash light on?Defender 110 2.4 TDCi Utility Station Wagon.

Technically, yes. I say technically because most people blank the EGRs when they've failed (which commonly reduces engine performance). So blanking them improves drivability (if they've failed) and means no more dirty air into the engine (if they haven't).2006 D3 HSE Buckingham Blue

Brilliant- thank for that.
My plan is to blank them myself and then I can get the ecu flashed at a later date.
Oh, and don't forget to remove the butterfly from the throttle body.2006 D3 HSE Buckingham Blue

Do you mean the EGR throttle body? Is that to stop it getting stuck?Defender 110 2.4 TDCi Utility Station Wagon.

No, I mean THE throttle body - where the EGR pipes feed the recirculated gases into.
Read this but bear in mind this is pipework removal as well (hence the blanking kit used)
