Hello Audi drivers… I bought a new 2021 Audi A8L and had my share of issues already. The MMI screen blacked out so the dealer replaced the rear remote. But since then my rear sunshade switch on the MMI grays out while the car is in motion and will not allow me to lower or raise it.

Lower MMI and grayed out rear sunscreen while in motion.
It works great when at a stop but as soon as I get to about 15 Mph it grays out. The dealer said it’s working as designed and no codes found. Does anyone else have that happen?
