What the hell is wrong here? .. All of the sudden the car was only putting out 6lbs of boost as opposed to the normal 15-20. I didn't hear anything wrong, didn't smell anything, no warning lights either .. Then just worked again .. What went wrong?

Thanks
(I have the X-chip btw, in case it matters)

Default Something weird like that is happening with me..

When I first get in the car, it is boosting all over the place. Back slapping speed. Then it just goes away. No lights no nothing. I will be trying the VAG tomorrow.

Default Boost limp mode, often from a pressure deviation

It resets itself key-off, key-on, so you don't go into limp mode until it happens again. Pressure deviations can occur from boost leaks, etc. A DTC will be stored so you have to check with VAG tool to confirm what exactly happened.
