How long for the DPF?

[phil3012]

So basically if you live and work in London there is no point getting any car with a DPF.

Wish the manafacturers would tell you about it befoe hand

I think its only certain systems that have an issue.

My TT has one but as far as I know nobody has had any issues with it. One person on the TT forum has reported having the lights come on once.

I do know someone with a SAAB who had no end of problems though.

By the way all diesel cars will have a DPF in a few years to meet Euro V standards.

Is the engine in your TT the new Common Rail Diesel? They are supposed to be a lot more efficient and better with respect to emissions, in theory their dpf shouldn't fill up as quick.

Yep it is. I think they use the Common Rail in quite a few VAG cars at the moment.

I didnt realise they also had a DPF, I thought they met the standards without the need for a dpf, hense the reason for going comon rail.

Wrong about the addition of the fluid, there are two haphazard ways to meet emission standards - by putting in a physical filter (ie the DPF) or using an additive with the fuel (like that your are talking about, essentialy watered down Urea IIRC). Seat use the former, not a combination of the both !

Correct, due to the DPFs location ont he turbo a fluid is not required.

They did use it on the Passat and Superb I with the BSS engine, but thats because of the DPFs location and it dodnt get hot enough. That fluid is added into the DPF, iron filings in the fluid heat up and break down the soot, problem is they fill the DPF up eventually.

Given no other faults the DPF should last the lifetime of the car, however if due to a fault they reach 80% saturation you cant regenerate them even with diagnostic equipment as there is a risk of fire.

Done 30k since oct 07 & never had it on from driving.

Came on once when the sensor failed, which I dont count

My plan was clock the car back when it needs it's first service, and service it myself. Then when it hits 10000 miles again I was gonna take it to the dealers to get it "serviced" and get the stamp in the book.
If it is the case that the DPF needs to be changed at 20k then I am gonna have to think of palming this car off onto one of my staff and ordering a petrol FR.

Am I missing something

You are jokin aren't you about clocking your car ? If not

Does any one know how long a DPF filter is supposed to last and how often you are supposed to change it?

Thanks.

I guess in normal driving just outside the 3yr/60k miles!! Vag com does give values of what is left as a percentage I beleive. Seat have changes a few [ has a good will gesture] that I'm aware of but how long that will last is anyone's guess. .........................................

The percentages are saturation of the DPF, however by triggering regen you can get that back down to 0%.
