Hi, Sounds like neither garage knew what they were doing to be honest! Compete twonks as it takes about two minutes to reset both counters!! I use Nigel Snape for all my personal and stock cars. He's a Master mechanic, factory trained and ex dealer network so knows his way around anything Italian. He can reset both the oil degradation and mileage lights for you in minutes! All of his details can be found here: https://www.facebook.com/Master-Tech-Vehicle-Services-1503549283203097/
