any facts to prove this?
as long as there is no gas flow along the metal plates
there will be no erosion of the metal.
i did block the egr of my former D1 with a peace of
2 mm thin copper (cut out from a rain gutter) and after
230.000 km there was absolutely no erosion on that plate.
on my D3 i placed 20 eurocent coins in the egr pipe directly
after the erg-valve. they fit like they are made for this....
-> the 20 eurocent coin is a thicker material than the 1 eurocent coin
made from an alloy of copper, aluminium, zinc and tin.
the 1 eurocent coin is made from copper coated steel

The coin in the pipe is a roadside fix by the AA and some LR assist teams to get you home. You then get the car fixed properly.
The metal in a 2 p piece is not copper but a compound. I have no proof that it fails every time, but it will determinate over time. Can you afford to risk it? That's all I am saying

the 1 pence piece is a copper coated piece of steel.
but you are right, it´s on your own to take the risk or not.

For £10 - £15 and an hours worth of work, just fit a blanking kit.
No more worries

I did my EGR blanks last weekend... I'm pretty good under the bonnet but it took me 5 hours!
To be fair I hadn't soaked the bolts and had to drive it to my shed to get under cover from the weather.
In my defence though the instructions I had, from here somewhere, didnt say you need 10inches of extension bar and a universal joint to get on the left hand bolts properly. 3 hours in tools shops and all done

No-one mentions the butterfly! I thought that you had to remove it, otherwise the engine struggles to breathe when it is closed by the ecu.
Is that correct, you have to blank the two egr's and remove the butterfly disc. Volvo XC60 - does all that the D4 should have done

I would advise AGAINST removing the butterfly.

On a Diesel engine should runaway occur (engine runs on its own oil) there are limited ways of slowing the engine before it blows or causes damage.
Fully opening the egr valves will help (but these are blanked now) and the other is close the throttle flap.
Also it shuts at key off to reduce shudder.
Yes the throttle valve will close a little in an attempt to make egr flow but you will hardly notice it and its not continuous.
Also the throttle will have a drift measurement which will be a mile off when there is no flap (stop) fitted.
If runaway were to happen your instinct would be to hit the brake pedal, this is good as your ecu will see non demanded rpm at this point and try to shut the engine down by closing the throttle.

Had it happen on an old Defender in the middle of Birmingham , scared a few people with all the smoke but managed to stall it, being a manual. l managed to restart and drive home. Wouldn't fancy it in an auto !
One solution could be to drill a coupe of small holes in the butterfly to allow a small amlunt of flow.

Let's be honest here, if your diesel engine is stuffed enough to run on its own, then going bang would be no greater loss. Not to mention how many owners on here have even heard of an engine running on its own let alone know how to stop it.  You guys are gonna be busier than a test bench in a plunger factory!

A simple turbo seal can cause it and the repair would just be a new turbo :/
Drilling holes in the butterfly won't help, it closes until it sees a drop in airflow at the MAF so with holes it would close further.
An ideal fix would be to keep the egr valves running and have them fed fresh air through filters not exhaust gasses.
Engines do run away but its mainly controlled with ecu driven diesels. Plenty of D3s have needed turbos.

Having issues with my D3 that may be EGR related - how much would you expect an independent to charge for fitting & supplying blanking plates?
