Greetings to the round! I recently bought a Phaeton from 2013. Very satisfied, of course, is not a new car anymore, but I knew that before. I only have a small problem now, maybe someone already had it in the round. With me the display with climate control is temporarily off. In addition, also error Sign Assist. The next day it goes again and then falls after you have used the vehicle again again. Are Nav i and Climatronic control panel one unit? Unit in the back works yes. Has anyone ever had the same problem in the forum? LG John
