Lack of power

[Axetivo]

Hi, I've got a A4 B7 (2007) 2.0TDI (BLB).

Yesterday,  I noticed when i was accelerating, afterwards the car had no power, literally it ran like it didn't have a turbo. I rang my mechanic and he told me to restart the engine. Suprisingly, it helped but any of you maybe know what could be wrong with the car ? The car has about 200k miles so it's not new so I expect something to be at the end of its life span.

Thanks.

Hi...welcome to the Forum

Sounds like the turbo variable vanes are gummed up.

Nothing that a good cleaning solution and a damn good blast up the motorway wouldn't cure.
