Question about Cars & Trucks
Black smoke is fuel. One or more of the fuel injectors could be stuck open and when you shut it off, the fuel drips into the cylinder. When you start it, that extra fuel burns and blows out black smoke. Blue smoke is oil and white smoke is antifreeze/water.

If it just smokes when it idles, i'd be inclined to suggest it's the oil seals on the turbo... Leave it 10 minutes, see if the smoke starts, give the accelerator lots of gas to see if the smoke stops... If it does, then it's the turbo oil seals....

The only sensible way forward is to get a list of fault codes from the onboard diagnostic system and take it from there. You could either go to a VW dealer, or if you are technically minded you could buy a £15 interface cable, download some free "VAG diagnostic software" and run it on a portable computer.
There are lots of possible reasons for the problem and guessing will not really help. If these suggestions turn out to be sound, please give my reply a "Fixya!"rating, If they do not, please hold off rating and add a comment with more details so I can try to help you further. Cheers, D

Not sounding good if white smoke, usually indicates coolant into cylinders via bad head gasket or head, maybe intake leak, or piston rings gone. You, or someone didn't overfill oil by chance did you?
What's mileage & did you have any warning signs or did this just happen all of a sudden.

Sounds like your injection pump timing is off, an injector is leaking or a bad seal on your IP.
VW dealers have a horrible reputation when it comes to TDI's. Check out the posts over at www.tdiclub.com Those guys are very knowledgeable - and the first thing they'll tell you is don't take it to a dealer.
You can probably find someone in your area that has a copy of Vag-Com (scantool software that vw uses) software that could look at your timing. It definitely sounds like your dealer was throwing parts at your car because they didn't know what your problem is. If I were you, I'd copy and paste your post from here over at www.tdiclub.com
