BMW 5 Series Insufficient Cooling/Heating Issue

I own a 2013 BMW 5 Series with a gasoline engine and 72,311 km on the odometer. I'm experiencing insufficient cooling and heating in my vehicle. The diagnostic code I received is 20A701, indicating that the water pump output is out of tolerance. Could anyone provide insights or solutions to address this issue?

Wondering if this could be a sensor giving a faulty output. Or is this the water pump itself.? The coolant temperatures and oil temperatures and everything say they're fine and I've already changed the temperature sensor for the coolant.

It's possible that the issue is with the water pump itself, especially if the diagnostic code specifically points to it. Start by checking the electrical connections to the water pump for any corrosion or loose connections. If everything looks good, it might be necessary to inspect the water pump for any signs of wear or failure. If you're unsure, it's best to have a professional mechanic take a look, as a malfunctioning water pump can lead to engine overheating. Let me know how it goes or if you have any further questions!
