VW Audi Skoda Seat P2564 Turbocharger Boost Control Sensor Circuit Low
The P2564 code stands for Turbocharger Boost Control Position Sensor Circuit Low. It is commonly seen on VW Polo, Audi, Skoda, and Seat models with 1.0 TSI engines (also found on 1.2 and 1.4 variants). This error often triggers the Check Engine Light, limp mode, and loss of power.
What is the P2564 Code?
P2564 indicates that the ECU detects low voltage from the turbocharger actuator position sensor. This can mean a failing actuator, wiring issue, or mechanical blockage inside the turbo.
Symptoms of P2564
- Check Engine Light illuminated
- Loss of power, especially during acceleration
- Limp mode activation
- Poor turbo response or lag
- Unusual noises near the turbo actuator
Common Causes
- Faulty turbo actuator (electronic or mechanical failure)
- Wiring or connector corrosion leading to low voltage
- Clogged or sticking turbo vanes
- Vacuum leaks or boost leaks in piping
- ECU misinterpretation due to intermittent signals
Repair Solutions
- Check wiring harness and connectors for corrosion or breaks
- Test actuator voltage and response with a diagnostic tool
- Replace the turbo actuator (OEM recommended)
- Perform a smoke test to identify boost leaks
- Clear the code and retest after repair
Recommended Diagnostic Tool
The iCarsoft CR MAX BT is an ideal scanner for diagnosing and clearing P2564 codes. It works with VW, Audi, Skoda, and Seat vehicles, giving live data and actuator test functions.
User Example
A VW Polo 1.0 owner reported repeated limp mode and a P2564 error code. After checking wiring and running a smoke test, the issue was traced to a faulty turbo actuator. Replacing it with an OEM part fixed the problem completely.
FAQ: P2564 Turbocharger Boost Control Sensor Circuit Low
1. Severity of the P2564 Code
This code is moderately severe. While it won’t immediately damage the engine, driving with low boost can cause performance loss and potential turbo damage.
2. Can I Still Drive with the P2564 Code?
You can drive short distances, but expect reduced power. Long-term driving risks further turbo and engine strain, so repair is advised.
3. How to Solve the Problem of the P2564 Code Yourself?
Check wiring first, then the actuator. If faulty, replace the actuator with an OEM unit. Perform a smoke test to eliminate boost leaks before replacing major parts.
4. How Much Does it Cost to Repair the P2564 Code?
Repair costs range between $150–$500 depending on labor and whether only wiring needs repair or a new actuator is required.
5. How to Clear the P2564 Code?
After repair, use a diagnostic tool like iCarsoft CR MAX BT to clear the code and monitor actuator performance in real time.
6. How to Prevent the Occurrence of the P2564 Error Code?
Perform regular turbo maintenance, avoid using cheap aftermarket actuators, and inspect connectors during scheduled servicing.
7. Is the Turbocharger Itself Always the Problem?
No. Often the actuator or wiring is faulty, not the turbocharger itself. Always eliminate smaller issues first before replacing the turbo.
8. Can Aftermarket Actuators Cause Repeat Failures?
Yes. Many cases show aftermarket actuators failing within months. OEM parts are strongly recommended for durability.
9. Will Replacing the Actuator Reset the Code Automatically?
No. After replacement, the ECU must be reset with a scanner. Without clearing the fault, the Check Engine Light may remain on.
10. Other Notes About the P2564 Code
If ignored, the ECU may continue to reduce boost pressure permanently. Always repair early to prevent long-term engine performance issues.
