When should my Citroen C4 Grand Picasso's fuel filter, spark plugs and timing belt be changed?
When should I change the fuel filter, spark plugs and timing belt on a 2007 Citroen C4 Grand Picasso 1.8i VTR?
It depends on the mileage. Do you not have a driver's handbook with service details in it? This should indicate when the fuel filter should be changed (and might indicate when the timing belt should be changed as well). As for the plugs, they are rarely changed - only when at fault.
