its a generic only device
if you had a Ducato or Boxer or relay and wanted a cheap Obd entry and had an android phone i would suggest a Vgate icar pro BT4 dongle from ebay and Alfaobd.
But you have a Merc Sprinter base so i wont bother mentioning that. For £20 it may be worth having rather than nothing at all. I had a simular but VW specific device that i used to reset a code for 3 years before finaly buying the part and fixing it.
Always copy code info and freeze frame data before reseting, makes diagnosis easier.
