P1361 on BMW vehicles indicates that the engine control module (ECM) has detected a misfire on cylinder 10 and has cut off fuel delivery to that cylinder to protect the catalytic converter from unburned fuel. The ECM monitors crankshaft speed fluctuations and identifies which cylinder is not contributing power, then disables its injector until the fault clears.
Guidance is general and written for BMW vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
