Check Engine Light at 7000 miles
Got a 2016 c63s sedan, no tune, no performance mods, currently has about 7000 miles on the clock.
Car is due for schedule B service for a few days, and yesterday I got a check engine light. Not sure what could be the reason, the only non-exterior mod is a hard-wired BlackVue dashcam. Scheduled the dealer visit next week, but would really appreciate if anyone who experienced it can share your insights. Will overdue service cause the check engine light, even though it is barely driven after the service was due? Could the dashcam cause any issue here?
Many thanks!

Very early in purchase
one cold morning start the the check engine light came on and was running rough.
i shut it down restarted it and check engine light remained off.
engine was running normal.
took the car in for service A but came back with a clean bill of health.
but things could change when I take it back for service B.
maybe it might show up in there system for faulty coil.
The car has been running great so will see when I take it in.
my build date is August 2015

A check engine light (normally just called an MIL, or Multifunction Indicator Light) could be caused but hundreds of things within your vehicle, and the entire point of having the system is to report a specific code as to what it's seeing as a problem. Go to your local AutoZone (or equivalent store) and get them to pull the code for you. They'll plug an OBD scanner into a plug in the driver's foot well directly next to the hood release, and the entire scan will take under a minute if even that long. Once you have the code, you can look it up and see what it's saying is the issue. AutoZone will usually give you a generic-ish description of the code, but it's at least a good starting point to diagnosing what's wrong.

I'M also extremely auto tech savvy that's why I suspected the coil .
it's been my hobby since a teenager.

If the MIL turns itself off (as you described), it means there is no l ok nger a code for the scanner to pick up. It'll still more than likely be logged in the main ECU where the dealer can look for it, but the OBD scanner from the auto parts store will no longer get be able to pick it up. My dealer was able to see a misfire code on my car from several months earlier even though the MIL went away after a few restarts the day of the misfire.
