2008 Peugeot 207 HDi, It is giving an error message that Depollution System Faulty what is the cause and why?

this car is more than likely fitted with a particulate filter in the exhaust system which has a pressure sensor fitted to detect when it is blocked. that puts the warning on. make sure the exhaust has been refitted correctly, i.e no leaks, any sensor pipes/connectors are in place, or it could be a coincidence that the particulate is now blocked and needs replacing or regenerating, you can buy a fuel system cleaner that may help to regenerate.,try your local motor factors for help. the filter works by trapping soot particles in the filter but it gets blocked, and to regenerate it most modern cars do it auto by injecting excess fuel in to the engine to burn it off. like a self cleaning oven, but your car may need help to do this, hope this helps you.
