over fueling
 

Hi Chaps, can anyone tell me what the main cause of over fueling is .
I get a strong smell of fuel after a journey.
Would it be the lambda sensors playing up.

Have you checked for no leaks around the fuel filter ends first?

Just had service and all that was changed so no leaks etc.

Have you scanned for error codes?

I would be surprised if it was overfueling by the amount big enough to have petrol smell after driving. I would say it is either leaking fuel somewhere or it is not burnt because of misfires.

Was the smell there before servicing? I would not be first time that leaks occur after changing something.
