DPF Operation

[Transporter]

There were some links I posted a while ago (my have gotten lost when the server crashed) that stated DPFs were not mandatory (or rather that diesels did not have to meet the Euro 5 particulate requirement) on cars RELEASED before 31 Jan 2010 and SOLD/REGISTERED before Jan 31 2011.
I will have to run this past a legal opinion at some stage.

It is very simple and easy to remember; the car was approved and sold new with the DPF, therefor removing it or modify is illegal. But don't get me wrong, I like the DPF like you and many others. It's just good to know what is legal and what's not.

Here is the latest Victorian EPA Guidelines for Car Modifications. I'm guessing other states have their own versions.

If you can be bothered reading through the 10 pages, pretty much any modification that aside from a catchcan that plumbs back into the normal control circuit can be deemed illegal. So Provents plumbed properly are OK but freer flowing exhausts, oiled pod air filters, larger intercooler if pod filter used, ECU remaps or ECU piggy back boxes (unless ADR certified), larger/extra fuel injectors, larger carburettors, any non-OE boost management... basically anything that could alter the emissions at all from as designed.
And this is only a guide so Victorians, at least, can be pretty much assured that the enforcement can easily be even more stringent.

Based on this, most Victorian enthusiasts would have already broken the law so what makes a DPF special

There are fuel additives that can extend the life of the DPF and help it with regeneration process. http://www.cdti.com/pdf/PP%20DFX-DPF%20Data%20Sheet.pdf

I'm worried about the predominantly city driving that our mark VI golf wagon 77tdi does & this looks interesting is this or similar available in Australia (Melb)?

It is available from Cummins in 10L and expect to pay around $200.

Thanks for this, I gave them a call. The bloke I spoke to at Cummins said it had never been in the country before (Platinum Plus DFX-DPF) and that it would be $1200 for 4L.

Have you managed to buy it at the $200/10L price per chance? & if so do you have the contact details? Thanks

I've ordered Platinum Plus DFX-DPF and they sent Cumins Premium Diesel Engine Fuel System Flush 4.7L (has to be used with equipment for cleaning the complete fuel system). I took it anyway - it will get used.

$1200 for four litres!!!

You have to be kidding.....you could retrofit a new silicon carbide mantle in your DPF for that sort of coin....geez!

Think you may have ruined my Sunday. Its dawning on me. Think you said the DPF on my Jetta will last around 150,000 ks and then will cost about $4500 to replace. Or $4.50 for 150 ks of DPF usage. = $3.00 per 100ks? Another 2 litres of fuel /100ks equivalent.
Suddenly my 1.6TDI's fuel consumptions the equivalent of 7 litres/100ks? Or much the same as the petrol version.Whoah! Fool me.
Love the drive though.

Sorry mate, but that's the best estimate I can find, carefully hidden by VW no doubt.

It's not ruined, at 150k you will be out of warranty, even extended warranty only goes to 160k, and you can delete it with a higher tune, better fuel economy for about half from Gav at Custom Code. Would be a hard choice to pass up given the cost difference, and I can see a lot of this happening come DPF death time.

Also there are investigations in place as to the development of aftermarket, rebuildable DPF's using the newer titanate technology. Why you think I started a business?

No promises, but I'm on it.

Yes, It is expensive, because the 4L will treat at least 6,000L of diesel (@ratio 1:1500). By adding it into the fuel the DPF regenerates easier with the addition of the fuel borne catalyst (Platinum Plus DFX-DPF), since the soot particles will burn off at temperature somewhere in the range of 350 to 450 degrees Celsius, rather than 600 degrees Celsius.
You will also greatly improve the fuel economy.

If you do the math, that's still about $11 per 55 litre tank, which goes a long way toward wiping out any saving on fuel over a petrol model.

Add in the other differences in new car cost, servicing charges, the apparently inevitable DPF replacement, the fact that diesel fuel always costs more than it ought etc., and using the additive seems to make diesel ownership decidedly iffy.

I apologize that I misled you, that ratio is actually 1:1,500 or up to 1:10,000 which is as little as $2.00 per tank.

[Greg Roles]

Modern diesels are only cheaper if you ditch them at the 3 year warranty run out time most company / lease cars do.

[Greg Roles]

Here's some GOOD news for a change...new DPF's for $800 plus post from the UK. Hooray!!
