I have had the OBD Eleven dongle for a couple of years and used it with great success on my Leon so I thought I'd give it a go on my 2004 Lupo to reset the service light ( after servicing )
While in there I did a bit of fishing around and was able to set Auto locking (above 5mph) where the doors lock, selective unlocking (depends how many times you press the button and also switch on an audible 'chirp' when locking and unlocking via remote.
I know this is all available using VCDS but just thought I'd mention it's also possible with this device.
