I'm not sure if this has been confirmed already but after working at a BMW dealer for over 1 year now we finally hooked up my bike and removed the service light. Please note that not every dealer may be willing to do it and if they do they will likely charge you for the 10-15 mins it takes to hook it up to the computer but it can be done.
I forgot to ask. Honestly I'd learned to live with it but I reluctantly agreed to sell it to a buddy of mine who asked about it. We were curious about what other diagnostics we might be able to run but didn't want to take any chances.
Yes you can used KTM Diags, BMW Dealer Diags or GS911 to reset service spanner, good to see KTM have added the capability
