P2563 means the position feedback of the turbocharger boost control actuator - variable vanes or wastegate - does not match the commanded position, without an open or short being reported. GM's 2009 Duramax diesel table sets it when vane position differs from target by 15 % or more for 5 s (Type B, warning light after two trips). VW's 2014 Passat book treats a position signal above 4.5 V or below 0.3 V as implausible on the 2.0 L TDI (CKRA), and VW bulletin 21-15-06 links P2563 on 2.0 L TDI engines to kinked vacuum hoses, a leaking vacuum diaphragm or a broken adjustment stud on the turbocharger. P2562/P2564/P2565 are circuit faults, P2566 an intermittent signal. Boost is often limited, so power drops noticeably.

Likely causes

Kinked, twisted or leaking vacuum hose to the boost actuator
Leaking actuator diaphragm or sticking vanes
Broken or missing adjustment stud, actuator travel out of tolerance

Symptoms

  • Noticeable loss of power, limp mode
  • Check engine light
  • Underboost code P0299 stored at the same time
