I can smell petrol after using my car.It only lasts for about 15 seconds or so after switching off engine.There is no smell when engine is cold or whilst engine is running.There is no obvious fluid leak under the bonnet,under the car or from the exhaust.Any ideas?
I don't know if it makes any difference but the car is rarely used and is often sat on the drive not going anywhere!

Could be a leaking injector, that is leaking until pressure goes down.

I would also not rule out a leak. Check all fuel lines and connections, I would start there first.

Talking about a fuel injector. You could have a fuel pressure test performed to isolate it.
