Hello, my Audi 80 consumes an enormous amount of cooling water, so that after 150-200 kilometers I always have to refill 1-1.5 liters in the compensation tank. So far I have done the following to check where the loss comes from: Run the car clean cardboard under the car remained dry even after 10 minutes, no water drops on the cardboard to see No white smoke from the exhaust and also no exhaust gas deposits in the compensation tank or the water is not pushed out of the container-with It’s not like that. I’m really at a loss. Especially since a 0815 Wkst changed my thermostat 1 month ago and I already had problems with it, because it had forgotten to vent the cooling system. What I noticed was that I had the heating on very hot, it consumes more water than when it is out, but water consumes it enormously. Only if the heat exchanger is put or leaks I wouldn’t get wet feet??? Would I like to get wet feet? about advice and did very happy. MFG
