Why I'm not sold on the all-digital diagnostic trend
I've caught errors that screens missed just by listening to the unit's hum and feeling for vibrations.

Give an example of an error you caught by listening or feeling. Why did the digital tool miss it?

Ever had a weird grinding noise a vibration sensor just called 'normal'? I caught a bearing going bad because it sounded gritty, not just shaky. The digital tool missed it because its thresholds were too broad for that specific nasty sound, lol. Good question @the_jessica, sometimes you just gotta trust your ears over the dashboard.

My ears are practically decorative, but I still nailed a failing fan clutch by its whine. The scanner showed rpm within range, but it had a desperate pitch that data couldn't capture. Digital tools average everything out, so unique bad sounds get lost in the numbers. Why would a program flag a sound it's never been told is wrong? Machines only know what we program, and we can't program every odd noise a part makes before it dies. Sometimes you just have to listen, even if your hearing is as useful as a chocolate teapot.
