P2563 Turbocharger Boost Control Position Sensor A Circuit Range/Performance
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
Symptoms
- Noticeable loss of power, limp mode
- Check engine light
- Underboost code P0299 stored at the same time
Repair estimate
Typical range across vehicles; the real cost depends on what the testing finds.
