After I was installed today in the workshop 1.5, I unfortunately have to dampen my hopes for improvements in heating. On the 30-minute drive home on country roads outside, I noticed no differences from before. With a set 27 degrees, I have reached a somewhat compatible internal temperature, perhaps 20 degrees. With a set 22 or 23 degrees, cool air continues to come, especially from the middle nozzles. At high temperatures and manual settings, warm air comes, but somehow only sufficient if not all three outflow openings are active. It seems to me that nothing was done about the heating in this release, which would be consistent with other messages here. In summary: sobering and disappointing.Sure! Here's the translation of your sentence into German:What about preheating via the app? Does it work better?"
