In the 00s, my dad had an issue with the infotainment system of its Peugeot 407 that would no longer boot.

An official Peugeot mechanic told him that it would cost something like 4200€ to replace the unit, so he asked me if I could have a look.

After a quick search, I found an update for his system, burn it on a CD, and put the CD into its car.

The system updated, and then would work normally. Problem fixed for one hour of my time and a CD.

A lot of dealership mechanics are mindless flowchart followers that aren’t even allowed to use their brain.

Though I’m surprised “update” wasn’t a part of that official flowchart.

Have had dealership mechanics ignore my notes and identify a part as being failed despite my method of 100% excluding that part as being bad.

Theybare because they are trained to be. You are actively dissuaded from any diag work, because it can be harder to justify your hours to the customer and dealerships are awful. For a mechanic, its a good and bad job. Nevermind ASE certification that encourages the same. Only small indie mechanics have the freedom to do good work.
