If you had a little more software in your car it could automatically remediate the issue and you'd be on your way with no repairman involved or at least tell the repairman exactly what to fix. Maybe you could fix it with the step-by-step workflow on your console.

Half the time there’s a light on my car, it’s a damn sensor! More components mean more points of failure.

Check Engine Light being on comes standard

Mechanics call this the money light. :)

[bookofjoe]

Indeed. When I took my car in last winter because the light had come on for no apparent reason, as the car was running fine, they charged me $140 to take it out on the road to try to find the reason. No reason was found. Two weeks later, the light came on again (towards the end of 2022). The car was and is running fine. The light will remain on until July when I take it in for a scheduled oil change.

Sounds like it was an intermittent fault? If so, those are notoriously hard for any mechanic to diagnose. Cars _usually_ store code history but it's up to the manufacturer and often the data they provide to the mechanic with a scan tool is misleading or an outright pack of lies.

Or you could buy a $20 code reader and see what's causing the light yourself.

[bookofjoe]

But the mechanics using their professional grade code reader and related equipment couldn't figure out what's causing it. At least I'm comfortable with "unknown" after that's their diagnosis; I don't think that would be the case if I did it and got that result.

Nah it would figure out what is the best time and place to break, order you an uber, and Uber would psy you manufacturer for the order flow.

It would also show you ads while you wait
