Does this car have a DPF?

[BorkFactor]

Morning all, I am currently trying to figure out if my Dad's car has a Diesel Particulate Filter fitted to it.

It is a 2008 (08 plate) Audi A4 B7 3.0 TDI Quattro Avant with a manual gearbox. I think it is one of the last of the B7 shape cars, and it has the more powerful engine than some older ones.

I seem to remember seeing a way that you could check the VIN number and it would tell you, but I can't seem to find it again on Google.

Can anyone here help me out?

Cheers

I couldnt say for certain but the Euro 4 emissions regs came in 2005 and they sharply cut PM emissions, so I would suspect, that it might have. However, some searches on the net suggest that it might not! One guy said in the front of his service manual was the code 7GN - 'Emission standard, EU4, DPF preparation', and that when he had called Audi UK to query this, they told him his car did not have a DPF fitted (only the prep work needed to fit one). The number he gave was 0800 699888.

Then some one else said if its 2006+ and 233ps then it should have one. Things I've seen about the 276ps one, all mention DPFs though. More quick searches basically say some do, some don't, probably to do with having the updated engine or not. Best to call Audi I think, or at least try looking for that code in the service manual.

Could always try giving it a bootfull on cold morning just after start up and if you get a nice plume of black smoke out the back then its safe to say you probably don't have one (or you do and its failed LOL!)

If it's got a DPF then surely it should have a light on the dash to tell you a DPF regen cycle is needed?

If you message me the VIN I can check on ETOS (VW/Audi/Skoda/Seat Parts system)

Handy bit of consumer advice from Pistonheads there. Definitely worth making a sticky.

Yeah best call Audi. I did this before when I was considering buying an A4 tdi a few years ago.
They couldn't have been more helpful. Even told me all the work done to the car that they had on file.

Let us know if you find out.

As mentioned above, I'd be extremely surprised if it didn't, due to the Euro IV regs. I don't think it's possible to homolgate a diesel without a DPF in the EU now.

Thanks for the replies chaps, as far as I can tell there is no DPF warning light on the car. I assume they are meant to be on the rev counter? If so, I can't see any lights at all.

Will try booting it on a cold morning tomorrow and see what happens!

In 85k miles in VAG diesel I've only had that light come on once, after the garage bent the sensor when servicing it. I think people do seem to worry a bit too much about DPFs

Big thanks to Steve, turns out the car was not fitted with one from the factory but there is an option to have one fitted after market. Which I don't think we will be doing

Owe you one for that, cheers

Interesting that a 2008 car didn't come with one though, I wonder why that was?

One less thing to worry about though so thats always good. On 79k now and hopefully will carry on like that for many years to come!
