Gas smell

What may be the problem when I smell gas sometimes when the car starts or I turn the AC on?

Gas smell coming from the engine bay is to be investigated before more severe issue develop.

Is this with engine cold, after heat soak or regardless?

What mileage now ?
Any fault code from Evap system ??

Cold is normally when fuel rail pressure is the lowest.
Inspect around, use UV die if you have to.

If you smell gas, there may be a problem that is covered by the emission control system warranty. I would take the car to a MB dealer.
