Finally hit 1000 hours on my scan tool and it's all from one truck
It's a 2015 Freightliner Cascadia that's been in and out of my bay for the last two years. The owner just keeps ignoring the same small coolant leak that trips a sensor. Anyone else have a vehicle that's basically paying your diagnostic software's subscription for you?
Wait, you're still charging them for diagnostics every single time? Stella111 is right, that's wild. They must have paid for your whole scan tool by now.
