Die Anzeige "Jahreskontrolle" durch das Uhrensymbol wird in derselben Weise gelöscht wie die Anzeige "INSPECTION" der Verschleisswartung.



after resetting of the annual (clock) inspection the check control lights remain the same. Should there be the exceptional case that the annual service as well as the regular service/inspection light up at the same time, both can be reset one after the other, but there must be a 10 seconds interuption in between both resets.

perfect,as a 12/89 car that explains why mine shows the clock every year at the same time!
