If its saying check coolant level yet coolant level is good it might be the sensor and the knocking ? how many miles does it have it might be the crank shaft getting old I have on my Jetta knocking as well and thats what it is

My 98 Passat did the same thing. It was the Coolant Temperature Sensor. A really easy fix, most people can get to it themselves with minimal tools. No idea about the knocking.
