Re: Turbo serge/cavatation
Overboosting without enough fuel with a tdi tends to make it 'popcorn' and shudder under the spike. Especially prominent on the 74 kw setups with original injectors and especially if SOI has been fettled with.

Re: Turbo serge/cavatation
Like others mentioned, more info would be needed.
Boost and airflow log would be great.
Could be as simple as an incorrectly adjusted actuator.

Re: Turbo serge/cavatation
Ah engine code ATD thanks.Was thinking here is a brand new acronym again.
Yeah does it run well when you have low boost requested and at what kind of boost levels is this happening.
