Porsche Cayenne Turbo Coolant Pump Issue

This 2019 Porsche Cayenne Turbo came into the garage with an overheating fault. The fault code was that the coolant sensor at the head was at fault but on diagnosis we found that the coolant pump was the issue. This was due to a vacuum issue on the coolant pump.

We replaced the coolant pump, solenoids and the thermostat at the same time to solve the issue.
