This summary uses the existing diagnostic information shown in full below.
This code means that a part in the car's engine, called the DISA valve, is not working right because it is getting too much power.
The P1513 code indicates that the DISA valve control circuit is receiving a higher voltage than expected, which can affect the engine's performance.
The DISA valve is part of the intake manifold system and helps optimize airflow into the engine. A 'Control Circuit High' error means that the electrical circuit controlling this valve is experiencing higher than normal voltage, which can lead to improper valve operation.

Engine Performance
• Have the vehicle inspected by a professional.
• Avoid heavy acceleration until the issue is resolved.
Check with your vehicle manufacturer for warranty coverage on engine components.
The P1513 code is commonly associated with older BMW models equipped with the DISA valve system.
Moderate – It should be addressed soon to prevent further engine performance issues.
Driving with a malfunctioning DISA valve can lead to reduced engine performance and efficiency.
• Engine at operating temperature
• Vehicle in park or neutral
The DISA valve is located on the intake manifold, typically on the side of the engine.
Q: What does a DISA valve do?
A: The DISA valve helps control the airflow into the engine, optimizing performance and efficiency.
Q: Can I drive with a P1513 code?
A: While you can drive with this code, it's best to have it checked soon to avoid potential engine performance issues.
