Which CAN Protocol is the car is using and the Baud rate?

Hi Community,
i own a dongle since 2 years, but never could read / program the CAN Data on my Passat B7… Now, as i have a bit more time would like to get my hands dirty. Is there any guide on how to start with CAN configuration? At particular i have following questions:

  • Get CAN sniffer to work. I miss CAN Protocol name and baud rate for my vehicle
  • Can i program to close the side mirrors when the car is locked?
  • Can i Program to switch gears a bit later, by building up a bit more Revs first?

Thanks to everyone willing to put their to 2cents!
