P2563 on Audi
Turbocharger Boost Control Position Sensor "A" Circuit Range/Performance
P2563 on Audi vehicles indicates turbocharger boost control position sensor "a" circuit range/performance. Au7o has documented this code across 1 Audi model — most commonly on S7. This generic powertrain code sets when the PCM/ECM detects that the signal from the turbocharger boost control position sensor (which reports the position of the variable-vane or wastegate actuator) is out of the expected range or does not respond as commanded. It indicates the module cannot confirm the turbocharger boost control mechanism is moving to the position it requested, often pointing to a vane/actuator position-sensing or boost-control fault. Typical repair costs on Audi range from $3,000 to $9,000, depending on the specific model and root cause.
Common Causes of P2563
- •Faulty turbocharger boost control (vane) position sensor
- •Sticking or seized variable-vane mechanism or wastegate actuator
- •Failing turbocharger boost control solenoid/actuator
- •Wiring or connector faults (open, short, corrosion, chafing) in the sensor circuit
- •Carbon buildup binding the turbo vanes (common on diesels)
- •Poor PCM/ECM ground or, rarely, a failed control module

- Turbocharger Wastegate Linkage Rattle and Underboost (4.0T V8)2013-2018
The 4.0T's two turbochargers sit in the 'hot-V' between the cylinder banks, where trapped heat coks oil and wears the turbo bearings and wastegate hardware over time. A very common failure is wastegate-linkage wear: the hole in the wastegate arm where the actuator peg sits elongates, so the wastegate no longer seals tightly at rest. This produces a distinct metallic rattle on throttle-off or at idle and can cause boost-control problems and a P0299 underboost code. This is distinct from the NHTSA oil-strainer-blockage stall recall and from coolant-line failures — it is a mechanical wear issue of the turbo/wastegate itself in the heat-soaked hot-V location.

What does P2563 mean on Audi?▼
P2563 stands for "Turbocharger Boost Control Position Sensor "A" Circuit Range/Performance." This generic powertrain code sets when the PCM/ECM detects that the signal from the turbocharger boost control position sensor (which reports the position of the variable-vane or wastegate actuator) is out of the expected range or does not respond as commanded. It indicates the module cannot confirm the turbocharger boost control mechanism is moving to the position it requested, often pointing to a vane/actuator position-sensing or boost-control fault. On Audi specifically, this code is documented across 1 model.
What causes P2563 on Audi vehicles?▼
Common causes on Audi: Faulty turbocharger boost control (vane) position sensor, Sticking or seized variable-vane mechanism or wastegate actuator, Failing turbocharger boost control solenoid/actuator, Wiring or connector faults (open, short, corrosion, chafing) in the sensor circuit, Carbon buildup binding the turbo vanes (common on diesels). Specific causes vary by model and year — see the per-model sections below.
How much does it cost to fix P2563 on a Audi?▼
