Little late to the game but my gauge sucks too. Coming from Ducati, this is nothing new. I owned three of those and the gauge worked correctly on none of them. The sensor failure message seems to be a problem though. It will be nice if Husqvarna replaces the sensor. It’s a weird shaped tank and they probably reused the system from the KTM 390 with minor tweaks. Does anyone know if the KTMs have fuel level issues. I did a quick search and didn’t see any. Sucks. Why is this always a problem on bikes?
