You should be fine, MY07 onwards had the next level of Euro emmissions, both detect the EGR doesn´t seem to be working but the spec of the later Euro standard means it has to set off errors galore to get the driver to fix it.....IMHO I´ve had mine blanked for 8k miles now with no problems/errors whatsoever....

Who has done this mod and had no problems, my Disco is a Dec 2005 MY06 with 20k miles on the clock.


MY 06 , 140 odd KLMS on the clock and with no problems.Well , Only one but that was down to my own ineptitude at refitting the circlips on the manifold pipes.

OK reading from all of the above, it seems the egr blanking plates mod is fine only for early D3s ie. MY06 and earlier ? Giong to do mine MY05 in Sept after warrenty expires if still no issues arise untill then.

I'm not sure about ineptitude Discowex, that's a tough joint to re-make without the bespoke tool Smile

A tip for anyone following on - I managed by using waterpump pliers and a small screwdriver. The pliers are not enough by themselves as they don't allow a space for the catch to flip down. This is where the screwdriver comes in. On the side of the clip where the catch has to click down, put the screwdriver such that it's lying across the bottom of the joint. Then when you squeeze against that, there's room for the catch to engage.

Could anyone who has successfully removed the butterfly spindle explain what retains it?

I have tried to get mine out and it won't budge.

I can see two small lugs on the butterfly that look like they may engage in a small indentation in the spindle ? The plastic thing that the actuating link connects to (the bit you lever on) seems to have a thin outer edge and be sitting over a moulding in the valve body. Any details as to what retains the spindle would be most appreciated. I really want to get the butterfly out to maximise air flow Mr. Green

The butterfly strangles the engine intake and forces it to ingest exhaust gases. Removing it definitely improves/removes the typical hesitation you can get for instance on roundabouts - basically the butterfly will be causing the turbo to spin down through lack of airflow through the engine.

I have tried that! I have tried a screwdriver and a trim tool. I have levered pretty hard and I think I must be on the verge of snapping something! The plastic on the end of the spindle looks to be quite a thin 'shell'

It would help if I understood exactly what type of retention I was trying to overcome.

dont bother, some of us have had the same problem. Just remove the little plastic link the connects the spindle and the actuator, and set the butterfly wide open and put a small self tapper down the side of the plastic block on the end of the butterfly spindle to stop it moving. Job done.

HI Al,

That is what I have done at the moment but being a paranoid obsessive compulsive I worry that the self tap may fall out and allow the butterfly to snap shut and bog down the motor. I also want to remove the butterfly to maximise air flow and because its just the right way to do the job Big Cry Mr. Green
