So now im not really sure what the problem could be, or how to fix it. Desired boost pressure is ~2500millibar at the same time. Live data says boost pressure is almost identical to atmospheric pressure (~1060millibar) and when power is restored it goes up to about ~2000millibar.
Power is always low, but sometimes it is restored, but only for a few seconds top. No unnormal play or damage on the turbo at the new engine. Tried disconnecting exhaust, incase blocked, but no luck. Vnt actuator rod moves during startup, even tried changing the vacuum line from vnt to n75. Egr is blocked, DPF is cleaed out (from the old BNZ engine). Local scrapper is really helpful, so i got to borrow shelf parts to try solve my problem. So, i swapped the engine, and i still get the P0299 underboost code.
I was told the car was running just fine when they took it in (rear collision). I bought the car real cheap, and got a good price for a much lower milage BPC (174 hp) engine at the local scrapyard, so decided to swap engines instead. Story is some guy went to one of the best mechanic in town, and he told him the car had a turbo failure. Ive just swapped out the engine in my newly bought 2008 T5 due to turbo failure on the old engine.
