Fig 1: Unlocking With Remote Control Key Function Diagram - Illustrated On Model 220

Remote control key set to "selective unlocking"  When the "Unlock vehicle" button is pressed once, the remote control key  sends a radio frequency and infrared signal to the corresponding receivers in the vehicle. These receive the signal and transmit the information via the CAN bus to the electronic ignition/starter switch control module (N73)  . The electronic ignition/starter switch control module (N73)  checks the access authorization. If the access authorization is valid then the electronic ignition/starter switch control module (N73)  sends the command "selective unlocking  " via the CAN bus. The PSE control module (combined) (A37)  receives the command and unlocks the vehicle pneumatically  .

If the vehicle was locked previously, the PSE control module (combined) (A37)  unlocks selectively, i.e. only the driver's door and the tank flap. If the driver's door and the tank flap are already unlocked and another unlocking operation is requested the PSE control module (combined) (A37)  unlocks the vehicle universally so that the remaining doors are also unlocked. The remote trunk release switch (S15/1)  is enabled.

Remote control key set to "universal unlocking"  When the "Unlock vehicle" button is pressed once the remote control key  sends a radio frequency and infrared signal to the corresponding receivers in the vehicle. If the access authorization is valid, the electronic ignition/starter switch control module (N73)  sends the command "universal unlocking  " via the CAN bus. The PSE control module (combined) (A37)  receives the command and unlocks all the doors and the tank flap pneumatically  . The remote trunk release switch (S15/1)  is enabled.

The interior switches  are released when the vehicle is unlocked universally or selectively with the remote control key.
