Hello to all, The ACC with my 9000CSE 2.0T has the following problem: Only about 8-9 weeks ago the workshop had broken a gasket and thus the air fluid leaked out, so that there was no cooling function. After the error in the workshop was removed and the climate cooled well again, the following error occurred (could not notice it before, of course, because it was still relatively warm): At low temperatures (from approx. +4°C the windows suddenly fog completely. ler appeared several times a few weeks ago, when it was cooler in the morning and again today. After switching on the defroster function it only got worse and then after 2-3 minutes better. The fog really goes ratzfatz within a few seconds, than more than an unsightly thing. I am grateful for every tip, especially if he shows a simple solution 🙂
