Thread: 2 Defender Problems

We have a problem in the UK with Feul at the moment. Main problem is with the 300 and 200 TDi
The eco lot have got the sulphur levels in the Diesel reduced. This causes problems for 200 and 300 TDi's as they need the sulphur and reliy on it (same as the petrol needed lead). What this does is damage the Lift pump and the feul pump and injectors. This in turn causes the drive to the cambelt to stiffen and then throw the belt.
But on the way to this the power in the engine just goes and it becomes slow and non reposive. The worst contenders for this are the supermarkets that sell cheap feul. (as i said this is in the Uk don't know if the same is in Aus)
What we use to fix the problem is feul additives which add back the sulphur . This makes a heel of a differacne and gives you back all the power you have lost.


This could be a cuase of you problems but would not really explain the over heating
I think in my mind the only thing that could cause that would be if the cambelt and sliped one cog over. The truck would still run but would be slugish and run hot

yer it is funny as the over heating isn't consistant.
The lift pump has just been replaced. I also run a diesel aditive witch compinsates for low sulphor in diesel & is a diesel bug retardent. Thanks for your suggestion, if changing the filter don't work & noone has any other ideas I think it will have to go see the doctor.

Definitely check the lift pump. This is a reasonably common occurence with 300 TDi's. Goes alright along the road but dies as soon as a load is put on the motor.

Regards, Barry.

yer the lift pump has just been replaced it is only 2000 kms old. What should I be looking for & how do I test it ????

Hi
Could there be a blocked pick-up filter in the tank causing grief???

Gidget,

I running a loaned original spec lift pump in mine and will be putting in a new aftermarket job in this weekend.

I did notice that the lever that operates the diaphragm off the cam has a different shape.

I hope that this isn't causing the problem because if it is I might be finding out for myself. 8O

I'll let you know.

Yes you are right they are a very diffrent shape, I hope not for your sake, but let me know how you go' If it is the same as mine it won't fit. It is about 3/4" longer & takes some real jiggling & swearing to get in. Even a bit of levering of the injector lines, as it hits on them. If i have to do it again I would go genuine.

Problem 1

Slipping water pump belt or worn impeller ? Does the fan have viscous coupling, could be that too. Worn coupling will allow it to overheat.



Problem 2

Could be bad fuel, plenty about these days.
