Turbo/Supercharger Boost Control Circuit High
on 2013 BMW M3 E90 4.0L V8 S65 · RWD
What this code means
The signal from the turbo boost control solenoid circuit is above the expected threshold. This can cause overboost or erratic boost control.
Symptoms
- Check Engine Light
- Overboost condition
- Engine knock under load
- Reduced power mode
- Harsh acceleration surge
Common causes
- Open circuit in boost solenoid ground
- Faulty solenoid stuck open
- PCM driver circuit failure
- Damaged wiring harness
- Failed boost pressure sensor
Diagnostic steps
- Measure voltage at boost solenoid connector
- Check solenoid ground circuit continuity
- Test solenoid coil resistance
- Inspect wiring for opens or chafing
- Command solenoid with scan tool and verify operation
Repair notes
Repair open circuit or replace boost control solenoid. Verify no overboost condition exists after repair.
