Smell of fuel

I will have a closer look tomorrow, but can't see anything obvious.
Does it start as easily as it always has or does it “miss” on cold starts? The n54 engined cars can suffer from leaking injectors which can cause cold miss fires, haven’t really heard of it on n52 cars though :?

Starts and runs perfect.
Perhaps there is a slight leak, fuel builds overnight and perhaps vapours run over the outside vent, to be drawn in, as the heater fan is always on.
I will take cover off engine to look for anything obvious.
Only really noticed since it got cold and i assume the fuel doesn't evaporate off.
And my sense of smell came back after catching mild covid.

Possibly an exhaust leak at the manifold or downpipes. You could start the car and feel around the exhaust side of the engine for any blowing or listen for a leak.
Well today had a good sniff around the bonnet, nothing. Left the car cover on, jumped in and started.
No smell.
Then realised i always have the vent on re-circulation, so smell probably not from engine bay.
I also noted wind direction. I think the smell is fuel from the exhaust. Getting into the cabin. Fumes must pool in the cabin floor and then when i start it's sucked through and then i smell it.
