21 vehicles · 2 makes · $100-$20,000 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 2013-2018 Audi A8 (L, Premium, Prestige), 2012-2018 BMW 3 Series (335d, 335i, 340i, M340i), and 2015-2018 BMW M3, plus 18 other vehicles, with repair costs ranging from $100 to $20,000.
