Hi guys, man that was yesterday something. so about 4 days ago I noticed that my heater only blows cold air at the stand. I drive 10 meters it gets warm. Has made me think about it. Then so 3 days ago my engine temperature in the stand is again a bit over 100. And I thought to myself in the stand.. can be times. 2 days ago he got up to a bit over 100° when driving. And that was already strange. That was never with me. And that he was cold when he stopped bl Aest was still the case. And yesterday I wanted to go shopping, drove about 8 km and I noticed already at the beginning that the temperature rises so fast. And all of a sudden it was already at 105°, then I wanted to drive back but then it was already too late. In the cockpit really the hot water boiled. I thought I was crazy. I stayed standing at a bus stop, of course on a big road where everyone sees me…. Then I opened the hood and then squirted something. I was in a good mood. It’s the little overpressure hose that goes down from the balance tank into the cooler and ran out. It boiled right, the engine was quite hot. I then touched all the hoses because I installed a new thermostat 3 weeks ago. And what was the end of the song, the hose down was cold. I immediately thought the thermostat was back in the ass. I immediately got a new one from Audi myself. My uncle said the one from the Steel pits can be thrown out right away. Well, after the expansion I checked the new and the old thermostat, but the old one went very well? So, what’s broken then? Did I look at the wapu then, but also went. Maybe there was air in it somewhere? Because the sour got so hot and the thermostat didn’t open? Enough cooling water was in it.
