Recommended next steps
Whether a fault is urgent, drivable, or routine depends entirely on the cause on a specific vehicle, and that can only be determined by a qualified mechanic with diagnostic equipment. If a warning light is illuminated, the most reliable next step is professional diagnosis.
What does P0024 mean?
P0024 is a Powertrain (engine, transmission, fuel system) fault code. It indicates: "B" Camshaft Position - Timing Over-Advanced or System Performance (Bank 2).
This is a standardised OBD-II code. The technical definition is the same regardless of the make or model of vehicle, although specific causes and symptoms can vary between vehicles.
About Timing codes
Timing codes relate to the variable valve timing (VVT) system, cam position, crank position, or the correlation between them. On engines prone to timing chain stretch (BMW N47, Ford EcoBoost, VAG TFSI), these codes often signal a stretched chain rather than a sensor fault.
