Technical Should I blank the EGR valve?

[DoIDon'tI]

After my recent EGR cleaning experiences and the acceleration problems that other people have reported, I thought I'd get a spare EGR valve in. I bought a reconditioned one off ebay, then wondered if the car would mind if I blanked the EGR pipe off.

I connected the plug to my spare valve, then took the car for a drive - this simulated blanking the EGR valve as the one physically fitted to the engine would remain closed while the car wouldn't see a problem as it was still electrically connected to a working EGR valve.

The car drove very well with no problems, and no lights on the dash, so it would appear that I can drive the car with the EGR valve blanked off. I've since swapped the plug back over and put the spare valve back in its box.

The question for everyone is; should I? :chin:

I'm sure I can remember reading various articles about doing this, the general consensus was don't do it for a prolonged period as I think they said it could make the catalytic converter run at a higher than normal temperature due to to having to work harder on the emissions which may cause it to fail prematurely.

If im wrong ignore this someone with more technical knowledge may have a better answer.

I read recently that blanking EGR valve will cause increased emission of pollutants, will not cause any damage to engine components, though.
Not sure if increase of pollution emitted through exhaust pipe will cause MOT failure. Someone with Multijet 8v got EGR blanke? How long for you have had it like this and did you come across any problems?
Thanks

One more thing:
Some sources say that blanking EGR valve helps in short term, but might cause turbo failure in long term (due to higher temperatures in turbo spin).
