Service Reminder Display 2015 Type S

[2.2 TypeS 2015]

Hi all,

My car used to display an orange spanner symbol in the centre part of the Speedo clock when it needed a service. 

After servicing the car I could always reset the counter.

But recently I notice that the service counter is blank (3 dashes) and doesn't appear to be counting anymore. 

Is there a way of re-activating it as I'm concerned it also has a link to the DPF regen system?
