Turn L turn signal indicator and beep sounds and dash light shows dvr door open

Hello, these systems include a fairly complex network of computers. As an example, the driver's door switch assembly is a computer module that communicates over a network with the other computers in the system. When you have more than one issue occurring that's an indicator that a module or software could be causing these issues. So, it is best to take it to a Volvo dealer, or a European specialist comfortable with working on this vehicle. Good luck
