Yeah, I've subsequently found out it has a carbon filter apparently, instead of a fuel filter. At least that's what the dealer has told me. Will find out when I open the box underneath the car on the left-hand side in front of the left rear wheel.
There is nothing in that box to replace.Peugeot stopped fitting fuel filters on petrol models about 14 years ago.
Not sure what your Dealer is on about? carbon filter? that sounds like the AC pollen filter?
