To buy or not DPF - rocker8742 - 25-01-2015
Hi guys, looking at a car up for sale at the minute with DPF problems which seems like it could be a bargain
Car in question is a 2004 C4 Vts 2.0 HDI and he wants 700 for it. Says it has DPF problems but not given me a specific answer about what's wrong yet and needs 2 tyres.
Could it be just as simple as ripping out the DPF for a straight pipe and a map?

You've got enough cars Paul

Can everyone stop buying broken cars !!

The DPF needs to be present for MOT...unless you know the tester anyway!
Tbh, sticking a pattern DPF on would probably do the job, though it might need an Eolys refill as well.

Can I not just gut the DPF instead then?
RE: To buy or not DPF - Toms306 - 25-01-2015
Can if you want (although technically illegal), but then it will need remapping. I think the 2.0 uses a straight DPF, the 1.6 one is bent so cant bash it through lol.
RE: To buy or not DPF - cully - 25-01-2015
think they need a some sort of restriction in the dpf as there are pressure sensors before and after i believe
if you cut it out the sensors need mapping out
RE: To buy or not DPF - Toms306 - 25-01-2015
Yep, exactly that, the pressure difference is measured either side of the DPF block. The ECU expects a certain amount of difference so if it see's no difference it knows theres a problem and can go into limp mode.
