Have you ever had the dreaded “check engine” light come on in your European car? You pull over, check the code with your OBDII scanner, and it reads P0013. What does this mean and how do you fix it? We’ll break down everything you need to know about this common OBD code.
Understanding P0013: A Deeper Dive
P0013 stands for “Camshaft Position “A” – Timing Over-Advanced or System Performance (Bank 1)”. This code signifies that the engine control unit (ECU) has detected an issue with the timing of the camshaft on the intake side of the engine, specifically that the camshaft is timing too far ahead of the crankshaft.
The Importance of Timing
Imagine the engine as a complex symphony. The camshaft and crankshaft must be perfectly synchronized for the engine to run smoothly and efficiently. The camshaft controls the valves that open and close, allowing air and fuel into the cylinders and exhaust gases out. The crankshaft is the rotating shaft that drives the pistons. If the camshaft is not properly timed, the engine will misfire, run poorly, and potentially cause serious damage.
Why P0013 Occurs: Common Causes
This code can be triggered by several factors, including:
- Faulty Camshaft Position Sensor: This sensor is responsible for measuring the position of the camshaft. If the sensor is faulty, it can send inaccurate information to the ECU.
- Damaged Camshaft Timing Chain: The timing chain is a vital component that links the camshaft and crankshaft. If the chain is stretched, worn, or broken, it can cause the camshaft to be out of time.
- Malfunctioning VVT Solenoid: The Variable Valve Timing (VVT) solenoid controls the oil pressure that regulates the camshaft timing. If the solenoid malfunctions, it can cause the camshaft to be over-advanced or under-advanced.
- Blocked Oil Passages: The VVT solenoid needs a constant flow of oil to operate properly. Blocked oil passages due to sludge or debris can restrict oil flow and impact the camshaft’s timing.
- Low Oil Pressure: Insufficient oil pressure can affect the proper operation of the VVT system.
Troubleshooting P0013:
- Start with the basics: First, check the oil level and make sure it’s within the proper range. Low oil levels can affect the timing system’s operation.
- Inspect the Camshaft Position Sensor: The sensor is typically located near the camshaft. Ensure it is properly plugged in and check for any damage or corrosion.
- Inspect the VVT Solenoid: If your car has a VVT system, check the solenoid for any visible damage or leaks.
- Check for Oil Pressure Issues: If you suspect a problem with oil pressure, have a mechanic check it.
- Check for Timing Chain Issues: Inspect the timing chain for signs of wear, stretching, or damage.
Case Study:
A BMW 328i owner in San Francisco, California, noticed their car was running rough and the “check engine” light came on. They used their OBDII scanner and found the P0013 code. They took the car to a mechanic who diagnosed the problem as a faulty camshaft position sensor. Replacing the sensor solved the problem.
P0013: A Common Problem in European Cars
P0013 is a common code in many European cars, including those from brands like Audi, BMW, Mercedes-Benz, Volkswagen, and Porsche. The complexity of their timing systems and the use of VVT systems can contribute to this code.
Next Steps:
If you encounter the P0013 code, it’s essential to address it promptly. Ignoring this problem can lead to further damage, more expensive repairs, and potentially serious engine issues.

Frequently Asked Questions:
- Q: Can I drive with the P0013 code? A: It’s generally not recommended to drive for extended periods with this code, as it can lead to more serious engine problems.
- Q: How much does it cost to fix P0013? A: The cost of repair can vary depending on the cause and the specific vehicle. Replacing a camshaft position sensor is typically a more affordable solution compared to replacing a timing chain.
- Q: Does P0013 always indicate a serious problem? A: Not always. While P0013 does indicate a potential problem with the engine timing system, the cause might be something simple, like a loose connection.
