What changes are they?

Here you go!

Oh that one, It's old hat now and been in for months, I thought you meant something new.

My '06 A3 2L Tdi doesn't have one and I think some of the later ones don't either. (PD engines.)

[MJ85]

Jetta TDI 105 PS mark 5 does not have one.

60,000 miles in a mk6 golf I haven't seen the DPF light once, 180k in a 530d, not seen it once.

its just pointless scaremongering, it might go wrong it might not, same as a turbo, same as injectors, same as getting a flat tyre, same as anything running a car with consumable items. drive it right it wont go wrong.

a dpf is like any other filter in the wrong conditions its gonna get clogged up

They did, had a Mk5 1.9tdi Bluemotion as a demo, and the warning light was always coming on (normally after our old duffer drivers had been driving it) but this was in a fairly rural part of the world, not even a busy town centre.

My bad fellas, forgot they carried that engine through to the blue motion ones! I know my 2004 pd130 doesn't have one

whats wrong with DPF?

Nothing if you have no issues, expensive if you do ...

I bought a C30 a few years back, it had a DPF, I knew this.

What I didn't know that was due to the smaller engine (1.6) it needed a catalyst to kick start the re-gen, unlike my dads for example (D5 engine, 2.4) which is hot enough not to need one.

I had explained to the dealer I wanted to keep the car for a good few years, at no point did they tell me that due to the catalyst, the DPF needs replacing around 70000 miles (the catalyst leaves an 'ash' behind, which builds up, eventually blocking the filter, hence the replacement).

The car was coming up to the 70K service, so I got rid, I'm not paying >£1000 for a service.

I appreciate this came about due to my lack of knowledge, but the long and short of it is that, at least with the smaller engines, you save nothing. Sure, road tax is low (or nil in my case) but the savings don't even break even when you look at the servicing costs.

Maybe a bit more info?

My ML doesn't have a DPF.
My Brabus tuned E320cdi didn't have one either.

But if you're buying diesel and worried about the difference between £30 and £100 a year in tax it makes me think that 25-30mpg might not be enough?


Do you want new?

Go and hire a new 1.4tfsi A3 for £50 a week. No DPF, cheap tax and the same mpg as the 2.0tdi, in every day driving some are beating what they got on the 2.0tdi.


You doing loads of miles?
Budget?

You do realise that there is maybe £5 week difference in fuel between a diesel and petrol for someone doing 12k miles a year.

Going from a 2005 Civic Type-S 2-litre(160hp) to a 2012 Octavia vRS CR DSG (170hp and heavier) has cut my fuel bill over 14K miles by over £10/week. No problem with the DPF.

does the op have an allergy to dpfs or an irrational fear of them? I think both of these case can be cured by not jumping on the latest the motorist is being hard done by band wagon

If the salesman even knew what a dpf was do you think he'd lose a sale by being honest and anyway I've never known any salesman to know much about the product they sell.

I'm on my fifth DPF equipped car, all have covered high miles with no issues. Couple of them were 100k+miles without needing DPF work.

Just don't drive them on constant low speed, low distance around town journeys and you should be OK.

Do some googling, or at the very least have a mooch about on the many forums on here.

I suspect DPF issues are far worse in the mythical internet world than in reality.
150000+ miles here in DPF equipped diesels & no issues ( plus I prefer how they drive & have saved tens of thousands in fuel costs, thankfully I do not have a petrol car)

This doesn't need to turn into a petrol vs diesel thread, also people doing high mileages are less likely to have dpf problems.

I was just about to say this.

We need people on the thread that say do lower than 10k miles a year and let us know they have never had a problem with the DPF

All DPF systems use a catalyst to generate heat, the difference between your Volvo and your Fathers is the C30 1.6 diesel uses the PSA Diesel engine - the PSA system uses fluid, injected into the fuel tank each time you refuel, the fluid stays in the diesel during/after combustion, and helps to lower the light of temperature of the carbon deposits in the DPF, when the carbon burns, the fluid remains behind as an ash deposit, so over time, the regeneration of the DPF becomes more frequent as the effective volume of the unit decreases - and as you say, requires replacement at 75k.
