17978 - Engine Start Blocked by Immobilizer P1570 - 000 - - Intermittent Freeze Frame: RPM: 0 /min Torque: 158.0 Nm Speed: 0.0 km/h Load: 2.4 % Voltage: 12.46 V Bin. Bits: 00000100 Bin. Bits: 11100000 (no units): 0.0

this code is intermittent , means not setting all the time , you have a problem with key rf signal ,usually

what you need for the rough idle & hesitation ,

1- is to replace Cam sensor &

2-Crankshaft Position sensor*6+-

3- Also you have a low boost code, check all vacuum lines especially the turbo line make sure turbo actuator working correctly also the vacuum line to fuel pressure regulator check for any leaks
