Hello dear people, I have a problem with my Audi 80 1.8S. Everything started about 5 weeks ago when it suddenly got very warm on the highway (over 95°) and the fan didn’t sprang up. Had to drive next to it and find out that the connecting hose had jumped off of cooling water filling tanks. After I had plugged it up again and refilled cooling water everything was fine again. A few days ago I noticed that the heating was not warm at all. e(at current temperatures it is noticeable) and the temperature rose again over the normal value and the fan did not sprung again. Stopped, fortunately a stream next to the road and the water was filled up again. At home I found that the problem hose is even porous and needs to be replaced. I then got a new hose but during the assembly unfortunately the plastic nose on the cooler, where the hose is plugged on, is broken off(17 years old Kunststof f). Well, I got a new cooler and installed yesterday. Everything went so far without problems and the heating was warm after installation and ventilation also again (short test drive). First attempt of the highway ride: I noticed again that the heating remained cold – OhOh – I had already driven up – the temperature rose again. I just wanted to quickly to the next parking lot, the Temp. was just above normal value (ventilator apparently didn’t go again) there was a funny “crack noise” and the Lämpc I turned off the engine, turned on the warning flasher and stopped (on the track). The cooling water was just below minimum, then filled it up again and drove slowly to the next parking lot. Here I noticed that the car is also warm quite strongly smokes – especially visible in idling. Qualm looks white to grey-blue. I have refilled cooling water again in the parking lot(although it is not apparent that it is a lot v And the heater got warm again, the fan jumped on again. Continued driving – off the train. Then, I noticed when I was standing at an order counter of a fast food chain that the car was somehow strangely jerking in the standing gas. When driving away it then pushed very strongly until the second gear – but then everything was relatively normal again. I came home(15km) still. Did the faxes thick – what’s the problem with the car?
