2018 Mercedes-AMG C63 — intermittent hesitation pulling away from a stop

Every few days the car hesitates for a split second leaving a stop, then drives normally. No permanent warning light. I want to know what data to capture the next time it happens. Mileage is about 42,000.

I'd want a measurement, not a hunch. Write temp, speed, and in-gear vs coast when the 2018 Mercedes-AMG C63 does it — then decide on parts. If the cheap test changes it, stop and reassess. Happy to compare notes if your setup is different. Only after sitting overnight so far.

This is usually cheaper to test than to guess. Move a coil or plug on the 2018 Mercedes-AMG C63 if it's cylinder-specific and see whether the code follows. Don't erase codes until someone who can help has seen them. This is from a 2018 Mercedes-AMG C63 in Central Jersey. If you share a photo of the worksheet, easier to sanity-check. That's coming from doing this as an owner, not a shop. This is the version I'd tell a friend.

I'd want a measurement, not a hunch. Loaded-suspension checks on the 2018 Mercedes-AMG C63 catch play that a wheels-hanging inspection misses. If the cheap test changes it, stop and reassess. This is from a 2018 Mercedes-AMG C63 in Central Jersey. Learned this the expensive way on a previous car. Parking it somewhere I can hear it better next time.
