Turbo's gone.

vw will definitely charge, Danny down at RSD certainly knows his stuff.. i've never had to talk mk5's with him though!
Limp mode is certainly a possibility, now you just need to find out why its doing that. (AA guys although they have the diag software, they don't all know how to read the info)

just wait for T_T to bowl along with some knowledge!

Ha ha.  Turbos arn't really my strong area - other than they spin very fookin fast - about 160,000 to 180,000rpm !!! 

But Toph is spot on - take it to a VW garage, and get a full "on the fly" diagnostics done - with particular regard to "requested turbo boost" vs "actual turbo boost".  Or if the OP knows someone with VAG-COM, this can also do this.

Do the latest TDIs still use the VNTs, or variable pitch blades?, because these can sieze and go south.

And don't bother with the AA/RAC etc.  They are only useful for supplying new batteries at the roadside at rip-off prices.    Anything more complicated than changing a lightbulb, and they are fooked!

some specialists in my opinion are better than the dealers. the bigger and busier the dealer is, usually the better as they come across all manner of problems more frequently than say one in the middle of nowhere

I fully agree.  However, no matter how "small" a dealer may be, they are always better at diagnosis than AA/RAC.

No you pillock!   

The actual blades on the turbo are able to alter their "angle of attack" in the air flow.  This makes the turbo very efficient at low air speeds (low revs), yet minimises resistance to airflow at higher air speeds.  It is usually just the blades driven by the exhaust gases which can do this - but because they are immediately after the "big bang" they are not only subjected to some seriously hot temperatures, but also any "crap", such as burnt oil, or diesel soot can coke up the mechanism, and cause it to seize.  But I can't remember which position they seize at?

And another thought!

Has anyone checked the fuel supply, as maybe the fuel filter is blocked or contaminated?

Don't forget to "park" them in the proper position!
