You should be getting a CEL. That is a check engine light. Have the codes read (Some auto part stores will do it for free.) Bring back the exact error CODE. It should be in the form {P1234}.

Note: the standard code readers do no read all of the VW error codes, but it gets most of them. You need a special VW code reader to get the rest of the codes or to do adjustments to the computer. 

It sounds like you re going into limp mode so that should give you a code and may prove to be inexpensive, but then again it might be expensive.  Depends on what that code is and why the code was triggered.  With out a code, I suggest finding a local TDI professional

Note there is an outstanding on line resource called the TDI club where they can help you and help you find a local TDI expert.

If your car has a “wait to start” light, you need to obey it. This is the norm on a lot of diesels. Many of them will act this way if it is just started right up without waiting for the “wait to start” light to go off. I don’t know if this is your problem, but it’s the first thing that crossed my mind. It’s an easy thing to overlook if you haven’t dealt with diesels your whole life.
