Strong smell Petrol in Cab

[Chiroptera]

Hey. My GFs polo with no mods has just started to smell really strongly of petrol in the cabin. Any ideas where to start with this one?

1.2 tsi? Do you notice it when stationary? If so, it's likely this..

PCV valve (Ventil) - Skoda Roomster Mk I - BRISKODA

Happened to my 1.2 Fabia. It's under the plastic air pipe, goes into the valve cover, and should set you back less than $200 even with genuine part.

Is the petrol cap screwed on properly?

I only ask as i have done this myself, it was loose and it filled the cabin with petrol fumes
