2024 Tesla Model Y — check-engine light turned itself off — still scan it? — anyone dealt with this recently?

Intermittent stuff lies if you only catch it once. Get a real battery/charging test on the 2024 Tesla Model Y, not just resting voltage, before blaming a module. You'll know quickly if you're on the wrong tree. On “check-engine light turned itself off — still,” that was the fork that mattered for me. That's the sequence I'd use. Not interested in a five-hour wait for a shrug.

I wouldn't throw parts yet. Write temp, speed, and in-gear vs coast when the 2024 Tesla Model Y does it — then decide on parts. You'll know quickly if you're on the wrong tree. Write the result down so the next test isn't a repeat of the last one. Trying not to diagnose from the couch.
