check out my thread m8 on loss of power on motorway, not sure same prob but if it feels like someone suddenly switched off the turbo and it preformed like a non td then it might b the same prob, but i only learning the hard way at mo trying step by step fixes so prob someone with more know how will help you.

he'll tell you that you've either got a split on one of your boost hoses or a pipe has popped out of its fixings

turbo charger?

when that lets go you normally get blue / white smoke and also most of the contents of your engine oil will be gone

Did you check the oil level?

Did it bring up any fault codes?

The sysmtoms sound liek the problem I had with a problem with the pipe that connects to the left hand side of the EGR.
Mate that part is a fat pipe on the left hand side of the engine it goes upto the top left on the engine and goes into a metal thing which is the EGR, check that pipe all the way down and see if you can find any leaks.

I would be surprised if it was the turbo.

Sounds like a common pipe split or a pipe that has blowen off. The black smoke is unburnt diesel.

If your turbo has gone you would be seeing blue or white smoke and low oil levels.

Also you said he ran a diagnostic check and came to the conclusion that it was the turbo? There is no fault code for a blowen turbo that I know exists. Could be wrong?

As said sounds like a intercooler pipe has come off, if one did you may get a code which would relate to the turbo.
did they check the car or just scan it for codes?
