Has anyone used this function successfully? 

 

For example would the Adblue function reset and work? 

If you mean the factory reset in the infotainment system, then no.

 

the reset is just to remove all personal data from the vehicle and all user settings, it will not clear any fault codes or car faults.

 

Unless you mean something else by reset the adblue system?

No. It was specific to the ad blue range app which is registering 0 km. I the car functions fine. At the moment.
