last night i went to drive my 307 sw hid 110 and the antipollution popped up on the screen and the engine managment light was staying on . on the dash . my mate said it could be the fap filter as i had all the tank refilled the other day at peugeot and the warned me that the filter is slightly blocked but it should unblock its self . to me i think it has blocked up a bit more as my car feels a bit sluggish . can any one help i don't no what to to . how much is a new fap filter ?
