My 100k mile 2018 E63 Wagon has had a similar issue for the last month but intermittently and not even sure if it's coming from the front or back of car. Took it to my indy shop who evaluated it over a few days and couldn't get it to repeat, but saw no leak, fuel system issues, or codes. Have only smelled it once briefly since, in the last couple weeks.
I'm guessing some EVAP system issue as well, but not sure what I could even replace if I wanted. Anyone have any idea what replacing that system entails and would cost?

Tried uploading a video but it did not work…
check the low pressure fuel line clips, they tend to fail over time with the line expanding and contacting in cold weather.
I had two of them fail and the smell lasts about 10 minutes until the car warms up.
Check under the engine cover after the car set overnight outside, you will see a wet spot on the line, there are about 4 of those connections.

I had this issue in my car twice, first time it was the Low Pressure Fuel Pump and the second was the fuel line Campaign No. 2022070004 Replace Braided Hose of Low-Pressure Fuel Line or maybe you have fuel residue.
