P2362 Cylinder 11 Pressure Too High

P2362 is stored when cylinder 11 shows more combustion pressure than the ECM considers plausible. No manufacturer publishes it, because no twelve-cylinder engine with cylinder pressure monitoring is documented. On a diesel, excess pressure usually comes from the fuel side: an injector that leaks or hangs open adds fuel, injection timed too early raises the peak, and a sensor drifting upward fakes the effect. That this code family can also be triggered by software logic is shown by Audi's 2015 S3: a December 2018 bulletin, superseding one from 2015, cured the cylinder 1–4 versions with an ECM update. Sustained high peak pressure loads pistons and head gasket, so an ECM may shut the cylinder off. Harsh combustion noise and, after a shutdown, reduced power are the signs.

Likely causes

Injector of cylinder 11 leaking or hanging open

Engine control software misjudging the pressure

Injection timing too early for this cylinder

Pressure sensor drifting high

Symptoms

Warning lamp on
Harsh combustion noise
Loss of power if the cylinder is shut off
