Code P15D1 MINI Description

The P15D1 MINI diagnostic trouble code indicates that the coolant pump cut-off internal temperature is too high. This means that the temperature of the coolant pump has exceeded the specified limit set by the vehicle's engine control module (ECM). The coolant pump is responsible for circulating coolant through the engine to maintain optimal operating temperature. When the internal temperature of the coolant pump is too high, it can lead to overheating of the engine, which can cause serious damage if not addressed promptly.
