Hello, was yesterday a little longer with my Audi. I noticed something strange when standing at the intersection. And it steamed something out of the ventilation in the center console. Ventilation stood on windows and footroom. Roch also didn’t smear. Had actually no smell at all. Did I notice a few times now. Can’t locate however. Does something have to do with the Klimatronic? The next thing I noticed is that I think my differential makes Ge No howling, rather like a grinding. But that only makes itself noticeable if you let the car roll in the second or third gear on a level track or downhill. As soon as you step on the clutch, that stops abruptly. Does the soon over Jordan go or what can it be?
