Saw this on ADV in the 2023 Stelvio thread about being able to reset the service wrench:
"I was told the same thing after I purchased my Aprilia Tuareg 660, but decided to give the Aprilia specific OBD-Star a try anyway. Long story short, it works perfectly. The sale price was $375 delivered, similar to the GS-911 I have been using on my BMWs for over a decade. A friend of mine purchased a Mandello, and was given the same advice as me with my Tuareg. I suggested that he try the Moto Guzzi specific OBD-Star device. He did, and again, it works perfectly for about the same price. We each purchased them on eBay. The device takes some playing with to operate properly, as there aren't any good tutorials, but if I can figure it out, it's likely you can as well. Also, there is a lot more functionality available than just resetting the service interval. I just haven't gotten into that yet."
