Iirc its usually down to the egr valve or boost sensor needs cleaning if sluggish under 2000rpm

how do i clean them?

[mark_647]

There is a how2 on cleaing them mate, the EGR needs to be taken apart and cleaned once removed from the vehicle. Not sure about cleaning the boost sensor but its only little and should'nt be a problem ! These two go hand in hand when it comes down to being sluggish, before the turbo kicks in.....

Let us know ho you get on

will do mate cheers for the help.

boost sensor cleaned with carb cleaner and soft toothbrush

the egr can be cleaned this way too, the valve bit anyway.

split egr into valve and solenoid, follow how to and drill solenoid bit, then clean and lubricate before reassembly.

make sure you also remove soot from egr to maniold entrance

clean both egr gaskets or better replace with new.

repeat process every 3 to 4 months as routine maintenance

also change to branded fuel and do airbox mod. it just will
run so much better

cheers im not the best when it comes to engines especially diesels but ill do my best cheers for the help.
oh and the airbox mod is done already

[mparks8590]

egr is 4 bolts to manifold, best with deep sockets and wrench

egr to flexi pipe is 2 bolts again deep socket works well

make sure you don't drop the gaskets

split egr with torx bits

then drill egr solenoid as per how2 with 3mm bit

then give it a hefty thump with a punch to separate
solenoid from body

it seems complex but its really straightforwards once you've done it
