NSW DPF filter.

[Valleyboy65]

Hi guys,
I am struggling to orientate myself around this site. Before joining I came across some DPF related posts from you guys which caught my attention, and also some tune info and also talk of flash tunes here and there. I now cannot find them any more.
I have a 2007 128Kw transporter, with 211,000 Klm's. I am not new to diesel but am to new diesels.

I bought the van without much history and hence no Idea of it's service life, stupid really but being somewhat mechanical I just knew it was OK when test driven.

Have done several oil and filter changes at 5000 Km's intervals to flush through so to speak and for peace of mind.

I must admit the van is fantastic in every respect except one, it's economical, very reliable and fast, does not burn oil, between services, but now after 10 months I understand the van a lot more, and the DPF system.

I do mainly 80 Klm freeway trips every day M5 back and fore to work, but it seems that the DPF regens every 200 Klm's.

I have seen a few posts regarding deletion of the system and then tuning.

It's the tuning and deleting the dpf from ECU I am interested in. Can i get this done in Australia, the UK seem to have people everywhere that can do it.

I here you all saying oh no not another one Sorry. Also I am getting a vibe that there possibly could be a problem with the DP switch?

Could someone answer my sceanario for me. Remove dpf filter, smash out inside, replace. With nothing inside and if I loop out the DP switch, It will never regen again if it does not get signal to do so, would that work???

Any info greatly accepted, fed up with the flatspotting, surging, smoking out the rear, ( god help the people behind me when it regens, probably 1000 times more carconagenic than just the soot, blowing out, chemicals at high temperature take on a completely different state)
Cheers

It's not that easy I am afraid. 200km seems a bit too often, for a goo DPF. I'd find someone that knows how to check your DPF load in the ECU with VCDS and go from there.

Have a look through the ross-tec wiki

Hi Gavin,
Thanks for the reply, sounds good but not sure what you mean, all new to me, can you recommend any one who knows how to check my DPF in Sydney and VCDS ??? Sorry to be so dumb but this is a all a bit new to me, I need to get up to speed, I learn quickly. Sorry but is the ross-tec wiki in these forums somewhere
Cheers

Diesel Particle Filter Emergency Regeneration - Ross-Tech Wiki

This is how to force a regen but there's other things you can do to monitor what's going on in the DPF. The pressure swich you mentioned is a common failure point. It looks at the difference in pressure above and below the DPF. Just knocking the guts out of the DPF would trigger a constant fault due to there being no pressure difference measured.

The ECU is expecting to see some difference and when it get to a certain level it triggers the regen to burn off the soot.

The fuller the DPF the more often this occurs.

There is a list of VCDS owners, I started I but can't remember which forum it was in. It's a sticky so won' be too hard to find.

OK.
thanks, so the pressure switch is not just an on and off type affair.

With this forced regen you mention, it would seem that I will need some sort of scan tool, can you recommend something. Saying that this VCDS is the same sort of thing but can do a lot more by sounds of it.
Is it expensive?
I must admit My DPF light has never come on, so I assume all good, but it does regen a lot. Do you know if the DPF's have a life span.

Oh and another funny thing when the van is going through regen my ABS pulses and makes the van shake and judder when braking and coming to a standstill, weird.

Do you know if the DPF's have a life span?

Yes, they do, because it will eventually clog up with ash, which is incombustible (unlike soot).

The dealer is meant to take a reading of the ash level via the diagnostic computer initially at 180 000 km, and every 30 000 km thereafter.

I read into that as saying the DPF (on a Transporter, with the 128 kW R5 TDI engine) has a service life of around 180 000 km or more, depending on its history.

Thanks again for the replies guys,

Ok have booked van in to VW Campbelltown, to have a check over and hopefully I will have a better picture what's going on. (any one know if they are any good there?)

I seen elsewhere in the forums of the DPF opened up and washed out, that may be a go, the van is great other than this. I don't really want to delete it, and yes it is illegal here I know, but if it is so troublesome, it may have to go. Any one done the delete thing, I see a nice pipe from the UK pretty cheap. Can the delete from ECU be done with the VCDS?

Anyone like to share any other common problems with me, of this engine/van.

probably already been posted, if so can someone point me to it.

Ever so gratefull
Thanks

John, VCDS is the scan tool. It cannot program the ECU, The delete pipes I have seen from the UK fit early Transporters but don't replace DPF pipes properly, there no pipes for the pressure sensor which still needs to be in circuit.

The Pressure switch isn't just on/off.
