Are you blowing smoke out the back too? Any power loss at lower speeds?

Hopefully your egr valve is not bad. $$$
Have you ever cleaned it?
Is the connector on tight?

Best suggestion is to find someone with a Vag-Com and have them pull the actual code.

I did have power loss and it is not blowing smoke.
I have never cleaned it.
I will make sure the it is on tight.
I cleared the code and the car has been driving fine since.
I dodn't know where to go next. I would like to fix it so it doesn't happen again.

Clean it...it's probably clogged.
Or disconnect it, assuming it is closed, and live with the warning lights.

You need to get the diagnostic code.
I just had the same issue.
Diagnostic code said it was the temperature sender. (Located on the back of the engine next to the firewall and not easy to get to.)
Mine was either open or closed which told the car it was -40 degrees outside, (when it was about +50 degrees,) which caused the car to miss once or twice and blow some white smoke.
Replacing the sender solved the problem. Shop charged 1 hour labor, plus diagnostic fee and $28 for the part and something, (I don't remember the amount,) for the anti freeze.
Total charge was around $275.

the temp sender is a ntc(negative temperature coefficient device) , so an open circuit is infinite resistance, making the ecu think its -50

Pfreire727,
Did you find out what the problem was? I have the exact same symptoms on my 05.5. Going to try to get it scanned this week. Is the free checker at Auto Zone, same as the VAG COM everyone speaks of?

No, but it will provide a code just the same.

I got code P0299. Boost pressure regulation control range not reach.
I think it means that the actuator isn't moving freely. Might need a turbo cleaning or reman turbo.

...or not. A replacement turbo, and replacement EGR valve, and replacement MAF, did nothing for what was about to become mine. The dealer sold it, and I agreed to buy it, with this occasional fault cause still unidentified. I never did find the cause, but I did discover prevention methods that I passed on to the new purchaser when I sold.

If you're talking about this thread: http://forums.tdiclub.com/showthread.php?t=367384, do it . It should be a maintenance requirement on these cars and it's so simple to do on an inline engine platform as the turbo sticks out invitingly for you to clean,etc. Mine is still running as new after this simple procedure. Sometimes we have to fish for what the limp modes and CELs are really pointing to and IMHO, a clean turbo will prevent a bunch of them.
