P0245 fault code: Turbo/Super Charger Wastegate Solenoid 'A' Low

Can I drive with P0245? — Limit driving

Limit driving. A low wastegate-A drive can leave the bypass shut or unconfirmed. Stop if boost feels unlimited or the lamp flashes.

P0245 means “Turbo/Super Charger Wastegate Solenoid 'A' Low” — a fuel and injector circuits fault in the powertrain. Limit driving. Wastegate solenoid A is reading too low, so the computer cannot confirm that boost-bypass valve is being energised.

Hot systems

Never open a hot coolant cap — pressure can scald you. Exhaust and catalytic converter get hot enough to burn and ignite debris. Stay clear of electric fans; they can run after shut-off.

What does P0245 mean?

P0245 is a generic (SAE standard) powertrain code reported by your car’s engine control unit. It sits in the P02xx block, which covers fuel and injector circuits. The stored description is “Turbo/Super Charger Wastegate Solenoid 'A' Low”. The code itself tells you which circuit or system tripped the fault — not always the exact part that failed.

Will P0245 fail an MOT?

An illuminated engine management light is a Major defect at MOT (automatic fail) until the fault is repaired and the light stays off. The lamp rule is unchanged by a low-circuit label.
