help with a tempermental 300tdi defender

[deezyboy]

Hi all,

 

Basically my defender has decided it doesn't like driving up hills, you'll have to bear with me as im not that technical with them.

 

It will be singing along quite happily on the flat and down hill, but then when you hit an incline, there is no power at all, you change down a gear like usually, no response, change down again and you may be lucky and it pulls through a bit juddery or worse comes to the worse you end up going up the hill in first. Ive found im a gear down every hill at the moment, and this is with the truck empty!

 

If your going uphill in say 2nd gear, foot flat to the floor, the revvs almost bottom out way before they should and turbo is sounding but no power, just absolutely gutless!

 

Replaced the fuel pump in Feb 2014 at quite a cost, new turbo, lift pump, all new filters etc, but it is behaving now as it did when the pump went last year.

 

any ideas or tips? I've checked all hoses etc and cant see any leaks or splits, and have undone the lid on the bottom of the filter to see if there is water or anything in the filter.

 

Cheers

Hmm been a long time since I've worked on 1 it's the clutch ok? Does it start ok? Any smoke when your flooring it??

Check the pipes for de laminating.

Air cleaner to turbo hose delaminated and inner collapsing and restricting airflow ?

[woody paul]

Inter cooler blocked may be. Or week air fillet pipe that sucks in or has loss rubber in side.

Or a split in one of the hoses between turbo,intercooler and inlet manifold.

Take the fuel filter off and empty the contents into a container let it settle and see what's in there . Mate had the same problem with his on Sunday , turned out to be a blocked filter .

Looked ok with the wee plastic plug out too .

[stupro]

have you ever replaced the sender unit on top of fuel tank ? sounds like not getting fuel

[humpo48]

Sounds to me the engine is not getting enough air as said check intercooler and pipes etc

[wisecobandit]

Gutless on the flat or general as well as just hills?

Could be fuel pump again or boost pipes on the intercooler leaking. Assuming no unusual sounds or overheating?

Most things would effect general allround driving.
