I have the same problem. Do you have a DSG transmission? There are complaints on VW clubs about this problem. It seemed like an engine control issue but it is actually a confused transmission in my case. It seems to have trouble engaging and must send a signal to the engine to kill power. Recalibrating the transmission with VAG-COM made the problem go from a 3x daily issue to a weekly one. I have read that the DSG is very sensitive to oil levels. I am going to set mine properly and see if it helps. The calibration/adaptation only takes 10 minutes with VAG-COM
SOURCE: lack of power
Turbo failure is never normally intermittant so I doubt it is a turbo fault.
The wastegate relys on a signal from the ECU via the MAFS.
Mass Air Flow Sensors are very common to fail on VW TDi and this also fits in with your symptoms.
Kind regards
Lloyd
