P0245: Turbocharger/Supercharger Wastegate Solenoid "A" Circuit Low
14 vehicles · 3 makes · $100-$12,000 repair
Most Reported On
P0245 is an OBD-II diagnostic trouble code meaning “Turbocharger/Supercharger Wastegate Solenoid "A" Circuit Low.” This code sets when the engine control module sees an abnormally low voltage (a short to ground or open) on the control circuit for turbocharger/supercharger wastegate solenoid "A." The wastegate solenoid regulates boost pressure by controlling the wastegate that bleeds off exhaust pressure. When the circuit reads low, the computer can no longer trust its control of boost, which can affect power and emissions. This code is most commonly reported on 2012-2018 BMW 3 Series (335d, 335i, 340i, M340i), 2015-2018 BMW M3, and 2017-2024 BMW M240i, plus 11 other vehicles, with repair costs ranging from $100 to $12,000.

What you can do yourself, and what needs a shop
Reading the code, clearing it, and watching whether it returns is a driveway job with the right scanner. These steps are not:
- Module programming or software updates — needs the manufacturer software or a J2534 pass-through with a paid subscription.
- Replacing a control module — most are VIN-programmed and immobilizer-registered, so a new one does nothing until it is coded to your car.
- Airbag/SRS component work — a stored fault can deploy a live device.
If the vehicle is still under warranty, check for an open recall or technical service bulletin before buying anything — the repair may already be covered.
