Depullution system faulty
2010 Peugeot 407 2.0 litre diesel sport

Depullution system warning comes up if i accelerate quickly, full tank of fuel, cant go over 50 mph when warning on, car run a bit sluggish , light goes off after a couple of days if i drive like my granny would, but soon as I try to accelerate light comes back on, how can i fix the problem as it put me in some tricky situations when pulling out of junctions etc.

Unless scanned for fault codes , can only guess . Change fuel filter , check for partially blocked cat / exhaust
