The time to reach the correct engine coolant operating temperature has increased. Diagnostic Trouble Code (DTC) ‘P218100 - Cooling System Performance’ is stored in the Engine Control Module (ECM), the vehicle “ warm up” time is longer when compared to other vehicles of the same type. Technical background It is possible for the engine coolant Thermostat to corrode over time, this corrosion is due to an adverse reaction of the Thermostat material with the engine coolant. The corrosion and subsequent build-up of debris prevents the correct operation of the thermostat when closing, resulting in over cooling. The ECM triggers a DTC when the target engine temperature is outside of the specified parameter. Production change Under investigation. Measure With a confirmed Customer complaint of MIL activation, accompanied with DTC ‘P218100, Cooling System Performance’ proceed to replace the engine coolant thermostat, refer to 19 – Engine cooling – Coolant regulator (Thermostat insert) (V8 biturbo) – To remove and fit. Once completed, retest the vehicle to ensure correct functionality. Parts information Refer to the electronic parts catalogue (ETKA).
