Sound like the car is over boosting and going in to limp mode where the ecu limits the boost the car produces and resets when turned of and on.

The car needs to be scanned or connected up to VAGCOM to see what codes its showing but to be honest I would have it looked at by a specialist company to find out what’s wrong and don’t buy it till the owner finds out.

Any work on the turbo means the engine will have to come out and that’s major money.
