P1359 BMW Code - Misfire Cylinder 9 With Fuel Cut-Off

Quick Answer

As part of the CARB/OBD regulations, the Engine Control Module (ECM) must determine if a misfire is occurring and also identify the specific cylinder(s) and the severity of the misfire event and whether it is emissions relevant or catalyst damaging. Common causes include Faulty Spark Plug, Faulty Ignition Coil, Intake vacuum leak. 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.

What it means: P1359 BMW indicates Misfire Cylinder 9 With Fuel Cut-Off.

Code P1359 BMW Description

As part of the CARB/OBD regulations, the Engine Control Module (ECM) must determine if a misfire is occurring and also identify the specific cylinder(s) and the severity of the misfire event and whether it is emissions relevant or catalyst damaging. In order to accomplish these tasks, the control module monitors the crankshaft for acceleration losses during firing segments of each cylinder based on firing order.
The misfire/engine roughness calculation is derived from the differences in the period duration (T) of individual increment gear segments. Each segment period consists of an angular range of 120Â° crank angle that starts 78Â° before Top Dead Center (TDC).
If the expected period duration is greater than the permissible value a misfire fault for the particular cylinder is stored in the fault memory of the ECM. Depending on the level of misfire rate measured the control unit will illuminate the "Service Engine Soon" light, may cutoff fuel to the particular cylinder and may switch lambda operation to open-loop. All misfire faults are weighted to determine if the misfire is emissions relevant or catalyst damaging.

Frequently Asked Questions about P1359 BMW Code

1. What does the OBDII code P1359 mean on a BMW?

P1359 indicates a misfire in cylinder 9 with fuel cut-off, meaning the engine control unit (ECU) has detected a misfire and stopped fuel delivery to that cylinder to prevent damage.

2. What are the common symptoms of the P1359 code?

Symptoms include rough idling, reduced engine performance, illuminated check engine light, poor fuel economy, and possible engine vibrations.

3. What causes the P1359 code on a BMW?

Common causes include a faulty ignition coil, bad spark plug, fuel injector issues, vacuum leaks, or low cylinder compression.

4. Can a dirty fuel injector cause the P1359 code?

Yes, a clogged or malfunctioning fuel injector can disrupt proper fuel flow to cylinder 9, leading to a misfire and triggering the P1359 code.

5. How can I diagnose the P1359 code?

Diagnosis involves scanning for additional codes, inspecting the ignition coil and spark plug of cylinder 9, testing fuel injector functionality, and checking for vacuum leaks or compression issues.

6. Is the P1359 code serious?

Yes, it should be addressed promptly as continued misfires can damage the catalytic converter and reduce engine performance.

7. How do you fix the P1359 code on a BMW?

Repairs may include replacing the faulty ignition coil or spark plug, cleaning or replacing the fuel injector, fixing vacuum leaks, or addressing compression issues in cylinder 9.

8. Can a weak battery cause the P1359 code?

While unlikely, a weak battery or charging system issue can affect ignition performance, potentially contributing to misfires.

9. How much does it cost to fix the P1359 code?

Repair costs vary but typically range from $100 to $500 depending on the root cause, such as replacing an ignition coil or fuel injector.

10. Can driving with a P1359 code damage my BMW?

Yes, prolonged driving with a misfire can lead to engine damage, overheating, or catalytic converter failure, so it’s best to address the issue immediately.
