    Default Flat spot on CDTI 150-how many suffer from this-*POLL*

    Im intrigued as to how many people suffer a flat spot on the CDTI 150, mine is between 1-2k rpm.

    Mine suffers from this before the turbo spools up. I cleaned the egr which seemed to help but it is getting worse again after a couple of months so I might try replacing the egr.

    Mine doesn't, but with a new EGR, Inlet Manifold and EGR, it shouldn't do either !!!

    mine still does sometimes - not as bad since i had new egr, im trying to arrange a friend to strip down and clean the manifold so hopefully that will help

    has anyone noticed if the problem isnt as bad depending on the weather - i notices on rainy damp days mine runs a dream, i was told that the air is more moist and changes the airflow

    ok, when i'm in 2nd gear and 1500 rpm, it doesn't matter how hard I push the trottle it picks up speed rather slow until 2000 rpm then really pulls. Is that a flat spot between 1500 and 2000?
