This summary uses the existing diagnostic information shown in full below.
This means that when you start the car, one of the engine parts, called Cylinder 12, isn't working properly, causing the car to shake or not run smoothly.
The engine's computer has detected that Cylinder 12 is not firing correctly when the engine is starting.
P1364 indicates that the Engine Control Module (ECM) has detected a misfire during the start-up phase in Cylinder 12. This can be due to a lack of spark, fuel, or compression in that cylinder.
• Rough engine start
• Check Engine Light is on
• Decreased engine performance
• Faulty spark plug in Cylinder 12
• Ignition coil failure for Cylinder 12
• Fuel injector issue in Cylinder 12
Cylinder: A chamber where fuel is burned in an engine.
Misfire: Failure of the air/fuel mixture in the cylinder to ignite properly.
• Check the spark plug in Cylinder 12 for wear or damage.
• Test the ignition coil for Cylinder 12.
• Inspect the fuel injector for Cylinder 12.
• Replace the spark plug in Cylinder 12.
• Replace the ignition coil for Cylinder 12.

Moderate
• BMW 7 Series
• Mercedes-Benz S-Class
• Audi A8
• Regularly replace spark plugs.
• Perform routine engine maintenance.

Engine Performance
• Don't ignore the Check Engine Light.
• Have the vehicle inspected by a professional.
• Avoid hard acceleration until the issue is resolved.
Check with your vehicle manufacturer for specific warranty coverage on ignition components.
Misfire codes like P1364 have been common in high-performance engines with multiple cylinders.
Moderate – Address the issue soon to avoid potential engine damage.
Driving with a misfire can lead to increased emissions and potential damage to the catalytic converter.
• Engine must be cold.
• Vehicle should be parked on a level surface.
Cylinder 12 is located on the engine block, usually towards the rear in V12 engines.
Q: Can I drive with a P1364 code?
A: It's not recommended to drive for long periods with a misfire as it can damage the engine.
Q: How do I know if my car is misfiring?
A: You may notice a rough idle, hesitation during acceleration, or the Check Engine Light may be on.

Fitment Required · Vehicle-fitment part
Relevant when the fault points toward ignition-coil performance or cylinder-specific ignition issues.
Some ignition faults involve coil performance or cylinder-specific coil problems.
Match the coil to your engine and confirm the failed component before ordering.
