so far i had to replace one of the headlights for moisture inside.

now i have engine light on, i check the system and everything seems OK.

i didnt drive all day friday, the light came on saturday morning.

this morning the engine light is still on...

I will have to take it to service dept

i check the gas cap, open the hood made sure everything was closed properly.

not sure if its safe to drive the car

any suggestions are welcome, thanks

Safest bet take to dealer if you feel uncomfortable

You checked the obvious, gas cap. No change in gas purchases.
Safest is to tow properly ( flat bed or dolly for rear wheels, I prefer former). Dangerous to drive if the car sputters or stalls. If you drive call BMW and get their permission for authorization, and contact name. I think BMW weak point is the electronics, but then again there are so many. Check control message is stored?
Once at dealership get the OBD printout ( from key fob reader) to show the check fault, it not displayed get a printout from the full diagnostic equipment, for your own records.
Most likely minor nuisance as the car is so new but the potential cause is lengthy hence dealer will give clean bill of health. Do it before the Christmas closings, good luck.

per manual:
Emissions
▷ The warning lamp lights up:
Emissions are deteriorating. Have
the vehicle checked as soon as possible.
Canadian model: warning light indicates
the engine symbol.
▷ The warning lamp flashes under certain circumstances:
This indicates that there is excessive misfiring
in the engine.
Reduce the vehicle speed and have the system
checked immediately; otherwise, serious
engine misfiring within a brief period can
seriously damage emission control components,
in particular the catalytic converter.
