Depollution system faulty
Its telling you the cat or the exhaust gas recirculating system has blocked or failed. You need a specialist or dealer to ascertain what part. Its typical French, sorry.
Would it do harm to any part of the engine on my peugeot 407 hdi if i put 4,gallons of kerosine mixed with 4 gallons of diesel ?
The entire fuel system will need to be drained and purged (At the fuel pressure test port, Usually a scoville valve). The possibility of sticking of the piston rings could occur. Try removing the spark plugs and spray a liberal amount of PB Blaster into the cylinders and let soak for about 30 min. Then spin the engine to evacuate cylinders ,to prevent hydro-locking, reinstall the spark plugs. ASUMING the 407 is a gasoline engine, it should run. If the 407 is a diesel engine the mix should not have any adverse effect. Just keep adding fresh diesel fuel until rough run clears up.
