P1357 Volkswagen Code - Ignition Circuit Cylinder 1 Short to Ground

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 1, Ignition Coil Cylinder 1 harness is open or shorted, Ignition Coil Cylinder 1 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 P1357 Volkswagen Description

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. In order to accomplish these tasks, the control module monitors the crankshaft for acceleration losses during firing segments of each cylinder based on the 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 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.
