Turbo lifespan

No, not particularly. I does smoke on ocasions but it doesn't chuck it out. If anything, it'll smoke then flooring it from low revs, until it picks up.
muddyweb:
hmm. OK.. I was asking Allisport about other possible causes for your performance and he suggested that a faulty lift pump could be causing issues. That is often accompanied by extra black smoke when you floor it. (Over and above the normal 'turbo lag' levels)
The fuel sedimenter should be brimming full of fuel, if it isn't then that is another symptom.

Thanks Tim :wink:

How do I check that? As mentioned previously, I tried removing the drain plug, but got scared off when it seemed to turn a bit each way, but didn't want to undo. It's a plastic plug - does it just need gentle persuasion? I REALLY didn't want to break it (Belgium is coming up!!).
Is the presence of 1bar pressure from the turbo indication that all is well there, or could some part still be non-functioning?
Thrasher:
Gords,
Did you have a roofbox or anything else on the vehicle which might impede forward motion? Are you expecting to be able to accelerate in 5th around 70mph? Have you tried dropping a notch to pick up acceleration?
My experience with Piglet is that the autobox does shift at different times, and kickdown *IS* required to move from 70mph+
Has this happened since you played with the EGR?
Do you still have the old wheels - or someone close by - to swap them back and see if that helps?

We had canvas bags on the roof for the holiday, but not to/from Wales - the performance (or lack of) was much the same.
From around 50mph upwards, the word "acceleration" is somewhat extravagant! It's more a case of the speed increases gradually over time :wink:
I assume it's because of the altered gearing due to the tyres, but the power seems to be too high up the rev range. Talking of rev range ... what is the "red line" for a TDi?
Changing down to 4th doesn't have any effect unfortunately. It appears as though I have little power until around 2500rpm and the engine doesn't want to rev much past 3500rpm (rough figures).
While driving through France, on a few occasions I got it upto around 80mph and it managed that to hold that (on the flat) reasonably well. Getting to that sort of speed is only attainable downhill though :wink:
The EGR was removed post France/pre Wales. The take-off and low rev picup was much improved, but it did not affect the top end at all - although it (seemed to) get there easier.
I keep thinking/feeling it's some sort of fuel starvation, but haven't found proof of that. Otherwise, it just seems like it needs a few extra horses :roll:
Unfortunately, I don't know anyone around here with standard size tyres, nor do I have any.
