I did contact them and they were fairly willing to help. They said to take it to any garage I know to have a look and if it is something worse going on to let them (dealer) know and to take care of it. I ll take it to some ac specialists nearby me over the weekend and have them check the ac and have a look at the bluetooth as well. I live in Kettering by the way.
This is the "weird" wire.
I appreciate your advices.
