What P2563 means
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.

Symptoms of P2563
- Noticeable loss of power, limp mode
- Check engine light
- Underboost code P0299 stored at the same time
Common causes of P2563
- Most likelyKinked, twisted or leaking vacuum hose to the boost actuator
- PossibleLeaking actuator diaphragm or sticking vanes
- Less likelyBroken or missing adjustment stud, actuator travel out of tolerance
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2563 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 5 | Area: vehicle speed, idle control and auxiliary inputs. |
| 63 | The exact fault in that area. |
What to do next
- Note P2563 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P2563
What does P2563 mean?
P2563 means "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. It is a generic code, so it means the same on every make.
Is it safe to drive with P2563?
Drive gently and only to a workshop. With P2563 the car can go into limp mode (reduced power) to protect itself.
Will P2563 fail an emissions test?
Yes, it can. P2563 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P2563 to fix?
Difficulty: hard. A typical repair takes 0.5 to 5 hours of work. This is a job for a workshop.
Will P2563 clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
