Error codes and location of coolant pump c

[Morgin187]

Hi I am getting coolant leaking after driving the car. Pressure check show no loss. And there are no visible leaks by two garages. I was getting these codes three months ago and once cleared didn’t come back

P013600 - 02 Sensor Circuit, Bank 1 - Sensor 2 Malfunction
P332500 - Power Supply Terminal 15 Implausible
P26F800 - Coolant Pump "C" Stuck
P034100 - Camshaft Position Sensor Circuit Range / Performance
P014100 - 02 Sensor Heater Circuit Bank 1 Sensor 2 Malfunction

The mechanic is telling me it could be the water pump. But we also want to know the location of coolant pump c incase that is causing the leak. Any help would be great full as I use my car as a taxi and losing money whilst the car is off road. Many thanks

Coolant pump C is the stop/start heater support electric pump around the back of the engine near the right driveshaft. It often reports as being faulty (stuck, jammed or cavitating) when really it is the often identical intercooler pump on the front of the engine. We did two of this engine design main water pumps last week, one a Caddy the other a Superb, during the cam belt change; both were leaking and both had a faulty regulator ring. We have another to do, on a T6, on Monday.
