I tried to just block the vacuum system that activates the EGR valve but it was still smoking at idle and having a rough idle at times.
I suspected it was the EGR still being funny and after the delete set out below my idle smoke and rough running is gone.
Tools required
- Phillips screwdriver
- 10mm socket
- 12mm socket
- 2" Extension
- 12mm ring flat spanner
Open the bonnet and remove the engine cover using the 10mm socket to loosen the 4 screws and further undoing them with the screwdriver
Then remove all these 12mm bolts/nuts with the 12mm spanner and/or ratchet using extension as necessary. Be careful on the exhaust bolts as they round easily and are very tightly rusted in usually.
Block off the vacuum pipe that you remove from the EGR valve
Note : I didn't point out the brace on top of the tappet cover but it's very straightforward.
Bolt on your blanking plates at the opened holes by the intake and the exhaust using the existing gaskets that came out.
Replace engine cover
Close bonnet
Job done.

Re: 2001 3.2 Di-D EGR Removal
So you removed the whole thing and then just "chuck it away"?
Funny, but I was thinking the same yesterday when I blanked off the two holes. Why not take off the whole thing? It serves no purpose, and 'strues bob - here you did it!
I blocked the exhaust side off at the point in the top of your picture, because it looks like everybody is doing it like such. It is interesting that you blocked it at the other hole.
Thanks for sharing!

Re: 2001 3.2 Di-D EGR Removal
Hi 4E,
A stupid question if I may? What is the function of the EGR and what poosible influence would the removal have on fuel consumption?
Is the removal of the EGR in principle the same for a 3.5 ?
Your comments please.
Regards

Much to read here.
http://en.wikipedia.org/wiki/Exhaust_gas_recirculation
The gain of removing isn't beneficial in performance instantly but rather to prohibit gunk buildup in the intake manifold.
Over time (100'000km+ ) the crank vent oil vapours combine with the EGR gasses and causes a gunk buildup in the intake components. On petrol engines, the throttle body is vulnerable and can cause low rev issues.

What did you use for the blank-off plate and will it take any serious pressure?

Do you think that 3 mm aluminium plate will be sufficient to block off the exhaust side?4ePikanini wrote:I used 6mm thick steel plate.macjohnw wrote:What did you use for the blank-off plate and will it take any serious pressure?

Re: 2001 3.2 Di-D EGR Removal
I wouldn't chance it. The egt's are too high for aluminium. The aluminium head survives as it has constant coolant carrying heat away. The aluminium plate will only have radiant heat dissapation and I feel it won't be sufficient. It may not melt completely but may become maliable enough to deform and fail.
