Thread: Tdi turbo hoses replaced - lack of power still exists. Help?

Does it have an EGR?
I know some 300tdi's did
If it was stuck open you would have symptoms like you describe similar to what happens to the TD5.

EGR ? whats that?

I think there was/shoulb be a sedimenter or water trap or something mounted in the rear guard (visible near the wheel, from the outside) yes?
If so mine has been removed to allow space to fit the remote reservoir for the shock absorber. hmmm.

Valve clearances were done not too long ago... should be fine.

Vlad, I hope your sediment bowl hasnt been removed...a very simple but very effective bit of gear on the LR.

does your turbo sound normal but maybe a bit louder? more noticable whistle?

valve setting is the art of setting the valve clearances so that each cylinder recieves the same amount of air.

Pat if thats the sheet time for a valve adjustment where you work can I come work with you?

No, the TDI doesnt have a throttle butterfly, They are a horrid idea that are put in for one of 2 reasons the first being to create manifold vacuum to run the brakes because the designers are too lazy to install a vac pump on the engine the second is to make a diesel engine respond like a petrol engine so that people who've never driven a diesel before dont have to learn to adapt from one type to the next. Fortunately that idea died of in the mid/late 80's.

I'll be spanner swinging on friday arvo, wheel it on over after about 1600vlad.

EGR= Exaust Gas Recirculation, don't know if it was fitted to all 300tdi's but it will eventually give you problems if it is not bypassed or removed.

AFAIK EGR was never fitted to any Defender imported into Australia.
