The EGR and Turbo vacuum solenoid electrovalves are marked with a white dot.

The vacuum pipe sizes are the same for vacuum input and vacuum output so there is a white dot printed on the body of the connectors to help identify which is which.

The early 'pressure converter' electrovalves just have the white marking to identify the correct port (left picture) but later, modified pierberg units with the improved exhaust port have the words embossed in the body too.

The white paint circle indicates this should be connected to 'out' which would be either the EGR actuator or the Turbo actuator, depending on which location the electrovalve is used in.

Part numbers for these troublesome and difficult to access pressure converters have part numbers:
