I have a problem with my coolant water tank, I was driving along and my coolant level light started flashing on my Audi A6 quattro 2.7T sport 2000 V reg, So I stopped my car and checked the coolant level, it was all gone. I filled it back up and carried on driving, after another 10-15 miles the light came on again. So I filled it back up and it seems that my coolant is flushed out of the tank all at once and then my engine starts to overheat. I have asked several mechanics who said it could be anything, from my head gasket to my thermostat, now I dont want to leave it in the hands of a garage to be told its more than it is and have to pay money for nothing. I just need to know what the possiblilties could be so I know what to rule out or how to tell what it wrong with it.
