P1365 Audi Code - Cylinder 4 Ignition Circuit Short to B+
Quick Answer
The Engine Control Module (ECM) must determine if a misfire is occurring and 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 Ignition Coil Cylinder 4, Ignition Coil Cylinder 4 harness is open or shorted, Ignition Coil Cylinder 4 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 P1365 Audi Description
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 120° crank angle that starts 78° before the 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 cut off 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.
What are the Possible Causes of the DTC P1365 Audi?
- Faulty Ignition Coil Cylinder 4
- Ignition Coil Cylinder 4 harness is open or shorted
- Ignition Coil Cylinder 4 circuit poor electrical connection
- Faulty Engine Control Module (ECM)

Frequently Asked Questions about P1365 Audi Code
What does the OBDII code P1365 mean on an Audi?
1. P1365 indicates a problem with the ignition circuit for cylinder 4, specifically a short to B+ (battery voltage), which can disrupt proper ignition timing and engine performance. 2.
What are the common symptoms of code P1365 in an Audi?
Symptoms include misfires in cylinder 4, rough idling, reduced engine performance, a flashing or steady check engine light, and possibly increased fuel consumption. 3.
What causes the P1365 code to appear in an Audi?
Common causes include damaged or shorted ignition coil wiring, a faulty ignition coil, a defective spark plug, or issues with the engine control module (ECM). 4.
Can I drive my Audi with the P1365 code active?
Driving with this code is not recommended, as it can lead to further engine damage, reduced fuel efficiency, and an increased risk of misfires causing catalytic converter damage. 5.
How do I diagnose the P1365 code on an Audi?
Start by inspecting the ignition coil and its wiring for damage or short circuits. Use a multimeter to check for continuity and proper voltage, and test the spark plug and ignition coil for proper function. 6.
What repairs are commonly needed to fix the P1365 code in an Audi?
Repairs may include replacing the ignition coil for cylinder 4, repairing damaged wiring, replacing the spark plug, or reprogramming or replacing the ECM if necessary. 7.
How much does it typically cost to fix the P1365 code on an Audi?
Costs vary depending on the issue. Replacing an ignition coil typically costs $100-$300, while wiring repairs or ECM replacement may be more expensive, depending on labor and parts. 8.
Can a bad spark plug cause the P1365 code in an Audi?
Yes, a faulty spark plug in cylinder 4 can contribute to ignition circuit issues and trigger the P1365 code. 9.
Will clearing the P1365 code solve the problem permanently?
Clearing the code without addressing the underlying issue will only temporarily reset the check engine light. The problem will likely recur unless the root cause is fixed. 10.
How can I prevent the P1365 code from returning in my Audi?
Regular maintenance, such as replacing spark plugs and ignition coils as recommended, inspecting wiring for damage, and addressing issues promptly, can help prevent this code from returning.
