Dont talk to me about dpf's. What a bastard.
Theyre the diesel equivalent of a catalytic convertor, and a good idea in principle only. Ive got a megane 1.9 which i drive steadily, the whole point of a diesel is economy if youre doing a bit of mileage. Turns out, this is exactly what fucks up dpf's. And nobody told me. I guess when you buy the car new the system is explained to you, but 2nd hand i just found out the hard way. Mine clogged up and eventually it blew a pipe out and the car went into limp mode. Cost loads for a new part, and they guy from renault managed to put it onto the computer and in effect trick the management system into thinking it was fixed and it blew all the shit out.
As above, what I do now is once a week when i finish an evening shift, i screw the bollocks of it on the motorway for 20 mins or drive in 2nd or 3rd up a monster hill. Doesnt feel like its doing the right thing but apparantly it is.
I bet it will go down a treat explaining to the Hitler Youth of a traffic cop that im not speeding sir, Im just regenerating my dpf system by driving like a ****.
