Fap system uses a chemical to burn of carbon on a regeneration cycle. This happens when the car is at a set speed/load on a motorway it will inject the chemical and burn the carbon Effectively cleaning itself. This is a problem because if it's going through a regen cycle of around 10minutes if it's not complete the carbon isn't burned off till the next cycle and they often become blocked. And need to be manually cleaned or taken to a dealership for a forced regeneration. I believe PSA was the first to introduce it.
