2012 A6 Coolant Temperature Too High!
Hi
I have a 2012 A6 Prestige with 62k on it. After about 20 minutes of driving or less depending on outside temp and ac usage, the car over heats and I receive "coolant temperature too high" as a message. I of course turn the car off and let it sit and cool down. I took the car to get serviced and was told there was an air pocket in the coolant system which they say was low. I drove the car for another 20 minutes or less and received the same issue. Has anyone ever had this issue before? I don't see any leaks or signs of water, the engine doesn't even seem to be really hot. I'm wondering if it may be a sensor error, or is it really that the water pump and thermostat need changed. Any help would be greatly appreciated. Thanks so much....

The 2012 A6 is a C7 platform. There have been several reported thermostat failures with the 3.0L TFSI engine. Some shops replace the water pump too.
