Petrol smells from the exhaust from a 2019 Tsi 1.5

Afternoon , hope this has not been covered under under an other topic.

I have returned from a 50 mile jolly today and find that a slight petrol smell when we get out.Its not a strong smell but is noticeable at the rear of the car.

The car fuel consumption is fine , uses noi engine oil , smooth on tick over , drives very well.

Any suggestions on a possible fault as I am concerned to drive the car for my safety and that of other road users.
