P0248 Code: Turbocharger Wastegate Actuator B Range/Performance
🟠 Moderate severity · drivable
Drivable, but the second wastegate isn't moving as expected — avoid hard acceleration until fixed.
What P0248 means
The wastegate actuator B isn't moving the way the computer expects. It may be stuck, leaking vacuum, or moving too slowly, which keeps the turbo from controlling boost pressure properly.
Symptoms
- Check engine light is on
- Loss of power
- Overboost or underboost
- Possible surging under acceleration
Common causes
- most common: Stuck or binding wastegate or actuator
- common: Vacuum leak to the actuator
- common: Carbon buildup on the wastegate
- less common: Faulty boost control solenoid
How to fix it
| Fix | DIY? | Typical cost |
|---|---|---|
| Inspect and repair the wastegate vacuum lines | Yes | $10–60 |
| Clean or free up a stuck wastegate | Mechanic | $50–200 |
| Replace the wastegate actuator | Mechanic | $100–300 |
