Blanking the EGR Valve....?
Discussion
Sorry...Car is Volvo S40 D5 (diesel) Sport 2007. I've been getting mixed answers, some say it's worth doing, and some say it will cause problems in the long run. I'm abit confused whether I should do it or not. Of course, I will get it remapped, dpf removal, and fit Milltek exhaust sometime this year.
I don't want the engine light to come on, as it will be difficult to sell later on the year/s.

I most probably to a little test on my car, by blanking off the egr and see how it performs for a week or so. If I don't see any change, then I will fit the egr valve back on.
Thanks for all your quick and efficient replies, much appreciated
On the other hand, I have heard you can increase your stock turbo power/performance by 10% or 15%. This is what I was planning to do on my previous car, but I didn't do it in the end, as know one really knew if it could be done.
Has anyone come across this before?

I have an EU3 emission spec 320d 150ps. When I removed the EGR for cleaning I realised that this was not a good thing as 50% of the cross sectional area was blocked with sooty crud. I cleaned it anyway and refitted it. Noticed a little more free revving over the last 500rpm. I then disconnected and plugged the EGR control vacuum line. The engine became a little more responsive and no ECU light (EU3).
I have since replaced the valve with a replacement straight through pipe and upon subsequent inspection there is no crud build up on the replacement pipe.
Talking from experience, the removal of EGR on my engine brought an improvement in drivivability and slightly better economy 1-2mpg.
If you want to improve the performance, I suggest the above + a remap + de-cat. De-cat in particular brought an increase in drivabiility with the turbo spooling up 2-300rpm earlier.
What part/s would I need to blank off the EGR? My S40 D5 comes with the dreaded DPF, a remap, dpf removed, and possibly Milltek is on my wish list hopefully this year, along with the egr removal.

Will try remove the egr first, and see if there is any difference, otherwise the egr will be back on.
