Still sounds odd, as I flog the bejesus out of my TDI and the exhaust tips are yet to even get black. Absolutely zero soot on the back end of my car, and I've never noticed smoke, like ever!
Smoke equals a lack of air in combustion.

It's an ex demo & only used BP Diesel. Owner only picked it up a couple of week's ago, so they've probably one put in one tank of fuel from where ever.
That's not going to clog up a DFP 90% in a couple of week's!
When did they introduce DPF? I might be wrong but I think my 2005 Golf TDI 2.0 doesn't have it.
In PD engines only the GT TDI had one out of the 1.9 and 2.0 versions. The new CR engines all cop one now I believe??
i think thats right- guy at vw dealership said all vw cr engines now have em.
which is a shame, because every car i get from now until im dead (they're all going to be vw's or land rovers) is going to be forced induction, and remapped.
i know vw is gonna begin serving up some pretty tasty twincharged options, but id prefer to stay diesel (i like being slightly different, which is why i drive a poofs car). how how how to get around dpf issues in the year to come.

One thing we can be certain of is that work-arounds will come with time and experimentation by technically competent DIY owners.
I remember the introduction of the ADR Emission Controls for petrol vehicles in the 1970/1980 era and all the problems that were experienced with loss of performance, increased fuel consumption and lousy driveability. Work-arounds to overcome these problems for use by competent DIY owners began to surface within a year or two which reduced the severity of these problems until such time as the vehicle manufacturers developed the technology to minimise, eliminate then ultimately improve the degraded performance of emission-controlled engines.
My concern with my partner's DPF-equipped Eos is what is going to happen when we cannot obtain mineral diesel fuel and have to use bio-diesel with more than 5% bio content. I would expect VW are aware that bio-diesel with higher bio contents will be sold in Australia within a few years by government decree and that their current range of new vehicles will require modification to use this fuel if the current 5% limit is technically valid.
I am living in hope that a simple remap of the engine management system will solve this problem as my future plans include producing my own bio-diesel for my farm machinery and road vehicles [and possibly a boat if problems with marine use of bio-diesel can be minimised].

I'd worry as I intend to keep the car well beyond this point, but then again I'll never be buying a new DPF, that's for sure. Ludicrous price tag.
Not so sure about being competent, but work around is indeed in progress at Cog HQ. Currently working out how to fool the sensors into believing all is well when the DPF is being bypassed.

I've just stumbled across the DPF regeneration info in the newest version of VAG-COM. It's under 'Drivetrain'. FYI, here's what my car is showing:
Group 108:
Particle filter carbon mass (spec.): 14.4 (grams, I'm guessing)
Particle filter carbon mass (act.): 0
Group 105:
Requested regens: 3...
Looks like a number of things kick off a regen cycle, not only the pressure differential across the DPF. Maybe the folk with the VAG-COMs and laptops might be able to do some data collecting and head scratching.

IMO. Once there is enough diesels with DPF the tuning companies will solve the DPF issues for these with modded cars, it will be in the way of some mods and probably causing the problems, so they will have no option and come with some sort of software bypass or similar. And for these in unmodified cars DPF will most likely last life of the car, I mean predicted life something like 180,000km.
as we all may know, boys on the club can do egr delete/ minimize with vag com, but that seems to be for pre-pumpe duse cars.
but if the dpf is post-turbo, and all exhaust gas to pass through it, there wouldnt be any software solution for a dpf bypass, would there? wouldnt you have to physically get in the engine bay and have a play?

Ok, the typical DPF would be fitted with 2 pressure sensors, temperature sensor and OXY sensor, so there is a lot of the info going in the ECU where it is all processed in the software. It should/will be a piece of cake for APR and similar. Of course that could be illegal.

Yes but the practical minimum life is the length of the warranty. After that YMMV.
I had a cat converter fail in a Mazda after about 100000km. Basically, the ceramic fell to bits and proceeded down the exhaust piecemeal over many months of intermittent undiagnosable engine power loss - until the cat blocked with a big chunk of ceramic and blew a hole out the side due to back pressure.
Tuning companies could turn on the afterburners on heavy acceleration to regen the DPF more frequently....the flames would be a good selling point.

but fun!
as long as chipping oilers remains practical and reliable, im there......
