2023 Mercedes-AMG C43 4MATIC — random misfire code but engine feels fine

I'd want a measurement, not a hunch. Get a real battery/charging test on the 2023 Mercedes-AMG C43, not just resting voltage, before blaming a module. You'll know quickly if you're on the wrong tree. This is from a 2023 Mercedes-AMG C43 in DMV / Maryland. I'd want a dollar figure or a measured spec, not 'should be fine.' Not trying to scare you — just skip the expensive first guess. Video is ugly but it shows the hesitation.

Intermittent stuff lies if you only catch it once. Write temp, speed, and in-gear vs coast when the 2023 Mercedes-AMG C43 does it — then decide on parts. You'll know quickly if you're on the wrong tree. On “amg c43 4matic — random misfire code,” that was the fork that mattered for me. Learned this the expensive way on a previous car. Parking it somewhere I can hear it better next time.

I wouldn't throw parts yet. Move a coil or plug on the 2023 Mercedes-AMG C43 if it's cylinder-specific and see whether the code follows. Don't erase codes until someone who can help has seen them. That's the whole play. Your commute and mine probably aren't the same, but the test still applies. Happens in gear, not in park, for what that's worth.
