P0024 BMW Code - 'B' Camshaft Position Timing Over-Advanced or System Performance Bank 2
Quick Answer
This mechanism hydraulically controls cam phases continuously with the fixed operating angle of the exhaust valve. Common causes include Failed Camshaft Actuator, Variable Camshaft Timing harness open or shorted, Variable Camshaft Timing circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0024 BMW Description
The Engine Control Module (ECM) receives signals such as crankshaft position, camshaft position, engine speed, and engine coolant temperature. Then, the ECM sends ON/OFF pulse duty signals to the exhaust valve timing control solenoid valve depending on driving status. This makes it possible to control the shut/open timing of the intake valve to increase engine torque in low/mid speed range and output in high-speed range.
The intake valve timing control solenoid valve changes the oil amount and direction of flow through intake valve timing control unit or stops oil flow. The longer pulse width advances valve angle. The shorter pulse width retards valve angle. When ON and OFF pulse widths become equal, the solenoid valve stops oil pressure flow to fix the intake valve angle at the control position.
What are the Possible Causes of the DTC P0024 BMW?
- Failed Camshaft Actuator
- Variable Camshaft Timing harness open or shorted
- Variable Camshaft Timing circuit poor electrical connection
- Engine mechanical problems

- Common symptoms include rough idling, engine misfires, decreased fuel efficiency, and illuminated Check Engine light.
2. What does the OBDII code P0024 'B' Camshaft Position Timing Over-Advanced or System Performance Bank 2 indicate?
- This code indicates that the camshaft timing for bank 2 is over-advanced or that the system performance is not within the expected range.
3. What are possible causes of OBDII code P0024 in a BMW?
- Possible causes include a faulty camshaft position actuator, timing chain issues, low engine oil pressure, dirty oil passages, or a malfunctioning engine control module (ECM).
4. How can I diagnose the cause of OBDII code P0024 in my BMW?
- Diagnosis typically involves checking the camshaft position actuator, inspecting the timing chain for wear or misalignment, testing engine oil pressure, and scanning the ECM for any related faults.
5. Can driving with OBDII code P0024 in a BMW cause further damage?
- Continuing to drive with this code may lead to engine damage over time due to improper camshaft timing, so it is recommended to address the issue promptly.
6. Is it safe to clear the OBDII code P0024 in a BMW with a diagnostic tool?
- Clearing the code may temporarily turn off the Check Engine light, but it will not fix the underlying issue causing the fault code. It is important to diagnose and repair the problem to prevent it from reoccurring.
7. How can I repair OBDII code P0024 in my BMW?
- Repair may involve replacing the camshaft position actuator, inspecting and potentially replacing the timing chain, ensuring proper engine oil levels and quality, and resetting the ECM after repairs are completed.
8. How much does it typically cost to repair OBDII code P0024 in a BMW?
- Repair costs can vary depending on the specific cause of the code, but it may range from a few hundred to a few thousand dollars, including parts and labor.
9. Can I fix OBDII code P0024 in my BMW myself, or should I seek professional help?
- While some DIY enthusiasts may be able to address simpler causes like low oil levels, diagnosing and repairing complex issues related to this code is best left to experienced mechanics or technicians.
10. How can I prevent OBDII code P0024 from recurring in my BMW?
- Regular maintenance, such as timely oil changes using the manufacturer's recommended oil, inspecting the timing chain periodically, and addressing any engine performance issues promptly, can help prevent this code from reoccurring.
