I own an 02 a4 with the 3.0. I changed all 4 cam sensors since then I have a blinking coolant message. I verified that the coolant was topped off. (More than once). Is there a reset or could the water pump be failing? No matter how far I drive the temp gauge is still normal range. Is there a reset on the sensors? Still acts like I have a miss. Please any help is appreciated

Is the coolant level sensor on the bottom of the coolant reservoir plugged in?

What do the fault codes say? It's an important clue to what the problem might be.
If you don't have a fault code reader, borrow one from someone who does or buy your own.
