Hey all I had to join this forum just so I could say thanks to Broaden. My car was doing the same thing word for word was just about to get a tilt tray to pick it up and take it to Nissan when I came across this thread so I went home made a plate to block the egr and it started striaght away and after driving it about 50m it stopped blowing smoke and has been running sweet since. Can't belive it was a free fix and didn't cost anything so thanks again.
