My Triumph dealer told me they would charge $120.00 to reset the service light. This is Triumphs way of getting to you even if you do your own oil change and service. Glad members are now using the Dealer Tool to bypass. I asked the dealer why can't you guys just do it for free and he stated when they clear the service wrench to info goes to Triumph so they have knowledge every time they use it. I don't know if it's true but it sounds like something Triumph would do.
