ibought another 406 hdi last night in the view of breaking,
but after thinking about it its too clean and too new to destroy,

last owner say it as got a Fap problem itl drive for 10 mins or so and then Go into Hulk mode,
he says peugeot told him it needs the tank filling in the derv tank ?
what is this tank and what stuff shouid go in it ?
after driving it for over an hour its drove faultless its not as quick as my 2.0 hdi but its smoother and comfier

how soon and regular shouid it throw its sell into limp mode if the tank was empty ?
ideas?
thanks inadvance
