I'm assuming *some* if not most of this article applies to our GTD's and most newer diesel vehicles?? (perhaps not the Adblue system?)
An interesting read, but where once second hand diesel cars at 120K miles were considered 'just run in' and a good cost effective buy, the newer models will require either new/recon DPF's or at least the original one cleaned..... At what price??

Thoughts anyone??......

I think its a matter of years down the line you don't actually need the DPF as its not part of the MOT emissions you would put a replacement pipe in there as you can do now. You would have to get a tuner to remove the DPF from the ecu so it doesn't look for it?

The latest DPF VW's with common rail injection are far a more robust system than the PD variants so you may find they last longer.
I think that by the time these common rail diesels need a new DPF the cost for replacement will have come down anyway also as Keith has pointed out you can remove a problematic DPF and replace it with a DPF delete pipe as long as you also modify the software in the ECU.

On a closely related topic, the diesel I put in my car last night had 8% biodiesel in it (Esso). Will this cause any problems? I wouldn't imagine so as it is a relatively weak solution.

Yes, I suppose it'll be like replacement CAT's, when they first came out, the cost of a replacement (IIRC) was in the thousands, now I think you can pick one up for some variants of the Mk III/IV Golf for under £100!
I understand what you say about delete pipes and software mod's, but I was just thinking along the lines of future Joe Public who ain't got a clue (and don't want one! a clue, that is).......
Just wondering is all and what others thought :rolleyes:

Should be ok, it says no bio diesel in the fuel filler flap but I presume that means 100%?

Usually most fuel injection systems are ok for ~10% biodiesel. They can accept more, but usually the manufacturer (OEM) has to specify to the supplier (Tier1) that they want an alternative seals package to cover it.

Thanks mate :wink:

NP :cool:
FYI for all who read this: Basically the system components (i.e. all the metal bits) are fine running what ever blend, however it's the pressures/temps/viscosity/chemical makeup of the fuels you put through them that affect the rubber (oil) based components in the system as they will over time break down unless changed for something else i.e. viton or nitrile (which are generally green coloured)
