You need to reset the counter to zero.
Or it needs to regenerate. A blast down the motorway should take care of that, especially if you are doing lots of short trips.

Reset to zero.

This is gleaned from other posts on the forum, no personal experience.

Is this the Eolys Fluid ?

If yes, then the counter in the ECU needs to be reset to zero.
I had this exact issue. Needs either a DiagBox or in my case a independant garage used a Snap-On diagnostic box to reset it.
