1. A method for controlling an engine system, the engine system comprising an internal combustion engine, a controller, a clean emissions module (CEM), and a cooling system driven at least partly by the engine system for regulating a temperature of at least part of the CEM, the method comprising:
determining an exhaust gas temperature in the engine system; receiving an engine shutdown signal indicative that the engine is to be shut down; performing, based on the received engine shutdown signal and a determination that the exhaust gas temperature has exceeded a first temperature threshold, a predefined engine operation for the engine system so as to allow temperature regulation by the cooling system; and ceasing the predefined engine operation based on a determination that the exhaust gas temperature has fallen below a second temperature threshold, different to the first temperature threshold.
