Thread: My (more than usual) sluggish 300tdi

Thanks for that, yeah I thought the turbo fed a boost line to the pump which controls its advance...
They didn't say a whole lot over the phone but ill quiz them when I pick it up.
If it turns out that a new compressor wheel, exhaust and lift pump will keep her going another couple of years, ill look into it. Though I'm not too confident pulling a turbo apart...
Interesting what you say about the injectors.

Seems impossible to get a solid diagnosis on anything these days!

Did they show you, or provide any more detail?

Well yeah you're right, it doesn't drive too badly, just sluggish and rough on start up!
I'll pick it up this arvo after work and try to pick their brains a bit.

Unless they are Landy specialists i would be reluctant to go by their diagnosis, if all that was wrong you would struggle to get out of the drive.

Exhaust collapse - you can tell by looking at it.
Injectors - rarely fail so may just need a clean.
Turbo - thats a possibility.
Lift pump - cheapest fix but they will run without one.
Injector pump - last thing i'd look at (read expensive so lets not start there). When was the belt last changed, could have jumped a tooth or 2.

Not a Landy specialist.
The turbo sounds the most likely to me, so I'd like to find someone to look at who wont take me for a ride...
Ill replace the lift pump myself and was planning to upgrade the whole exhaust anyway.
They quoted 5k to fix it up... I'm thinking ill get it done for 1k or less hopefully....

When I bought my Disco I wanted to see how much boost it was developing so bought a cheap fuel pressure gauge and T piece and installed it into the pipe that goes from the turbo to the injection pump.
Just a thought on a cheap way to check if ya turbo is still working.

edit. Mine ended up showing a spike of 15+ psi and a constant 14-15 at WOT so all was OK.

Thanks dave, the test they did said it was putting out 14 psi. I didn't think that was terrible... Good tip though, cheers

They said the turbo was putting out 14psi, but the compressor wheel is blown? 14psi is (approx) max for a TDI. No need to be more accurate than that, it won't vary by more than 1 psi I wouldn't think. They have told you some very strange things IMO.

Yeah that's what I'm thinking...
Feels like Ive achieved nothing!

I guess I'm learning more about the old girl at least
