Just to clarify, I service the Citroen Berlingo every 12k miles aswell, and change the fuel filter every second service. The van's done 240k miles now so it's got plenty of chance for muck in the tank. The fuel filter on that is about half the size of the Altea filter and I've not seen it anything like as black as that.
They both get filled up at the same service stations aswell.
Anyway, a new pollen filter to
help stop the aircon smelling, a new air filter for improved breathing, a new oil filter and fresh oil for smoother running, a new diesel filter for the same, and I asked the wife if she noticed anything different about the car. She said...
"You've put some apple scented screenwash in, haven't you."
