Crikey. Well, I am out of my league on most of those faults, but I struggle to see how you have so many serious faults and it's still running like it is. I would have a lot of questions.... Hopefully someone else can comment.Quote:

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!
Well yeah you're right, it doesn't drive too badly, just sluggish and rough on start up!Quote:

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.Quote:

I guess I'm learning more about the old girl at least:)
Hey Mate,
These guys are having a laugh! As has been said, you wouldn't be driving if all that was gone. 14PSI with a blown turbo?!?!?! Serious? I'm failing to understand their logic here.
You are right, the turbo is a definite candidate for your issues, but if it IS actually putting out 14PSI I would be struggling to understand what would be wrong with it.
Also as has been said before, no boost, no advance. Exhaust collapse is a new one, not something I would have even dreamed up to be honest. Could cause issues, but it will be painfully obvious to look at.
If you suspect the injectors at all, it's easy enough to get them cleaned. There are a few mobile guys and others with workshops, if you can remove them and refit them yourself it will be cheaper. It's normally around $15 to $30 per injector.
Don't give up on the old girl though, they are great cars! On the turbo, it could be a good excuse to fit a VGT!! :eek::twisted::wasntme:
Good luck mate, hopefully you can have her sorted soon.
