What age of navara?My wonderful navara seems to have developed another problem, that seems to be the egr valve . What I'm looking to know is, if I block off the egr will it put on the engine management light or is my mechanic talking rubbish?
What age? I have a 55 reg navara (old style) that developed a misfire, almost like a blocked fuel filter, changed the filter but no different. It turns out that the problem is caused by the 'neutral position switch' apparently this cuts the fuel on overrun.
Egr wasn't giving any problems, I just didn't think it was very good for an engine to be breathing it's own excrement.It's an 09 model 75k on the clock
I have just fitted an exedy clutch and single mass flywheel and he complained about fitting that, his reason that nissan fit the dual mass for a reason!
Did your egr give trouble before you blanked it? Where does the dpf thing live?

Diesel particulate filter (dpf canister) lives as part of the exhaust. I think the fuel economy was improved on yours in comparison to my '57 plate, and at 95k it's obviously not giving you any bother.
Plus it sounds like you're having enough trouble with your mechanic
I have a 2009 D40. I put a blanking plate in egr in 2011, done 100 thou since. No issues, no lights. Put old school flywheel and clutch in about 8 months ago when original let go. It was 2 days before last Christmas. Rattley old sod at idle now, but throttle response is transformed. You can actually get the bugger to shift a trailer now. Manual trans D40 has no dpf.My wonderful navara seems to have developed another problem, that seems to be the egr valve .

How do you know it's the egr valve? Reason I ask is because if it's already forked it'll need replacing and then plating.
Mine started showing the eml which could be reset by the battery. After a few weeks car died on the road with a trailer. Would hardly start, wouldn't rev up and smelt like a sort of chemical tar factory. Turns out the flap had fallen off the egr. The valve position sensor goes home. No choice but replace. £230 if I remember right.
Could be your suction control valve thats causing your problem, have a read of navara forum.
Thanks, any ideas what it would cost and what sort of improvement I could expect?
