P006F
Turbocharger/Supercharger Boost Control A Supply Voltage Circuit High
Supply voltage to boost control actuator A above expected range. Same as P005F but on actuator A. Boost control tracks commanded vs. actual manifold pressure; persistent deviation means wastegate, vanes, hose or actuator are not delivering the requested pressure.

Possible causes
- Alternator regulator failed high
- Connector pins corroded - high contact resistance low
- Supply wire pinched against B+ source low
Symptoms
- Charge status indicator shows fault
- Charging may not start or interrupts
- Slower-than-expected charge rate
Inspection / repair
- Difficulty: medium
- DIY: possible
- Estimated cost: 50–600 €
- Estimated time: 0.5–3 h
- Component: boost actuator supply
- Component: charging system
- MIL / check engine light
- emissions-relevant
- limp mode possible
