It is to swirl the gas flow so that the adblue mixes in properly, rather than a big wet lump which then crystallises.
T6 204 DSG 4Motion DPF removal
- Thread starter Cog Head
- Start date
Good afternoon all
The DPF has had two overnight soakings, and a flush with cold water with added airline, which works a treat, by far the best at clearing the muck out.
Got it all back together and it’s sooo much quieter now, so it’s definitely done something.
It’s currently ticking over on the drive drying the DPF out before I drive it, I know the turbos are quite sensitive to back pressure.
Next step… how do I teach it that it’s has a “new” DPF, or is there a cleaned DPF setting?
Do I need to code in the new particle sensor? There’s no engine light on…?

For a new DPF you would enter 0 grams. For a cleaned DPF perhaps 10 grams (would equal to 20000 miles. Anyways, I don't think it really matters.
No coding needed.
Well, in the DPF there surely is no soot to burn. Personally I wouldn't bother. Instead I would run the EGR test to capture the new pressure readings across the DPF
Hi all,
Just been reading your messages regarding T6 DPF cleaning, I'm in a similar situation, got a niggling DPF code flagging up (P226D), had it in for a forced regen at the local garage but code came straight back unfortunately, so I'm looking to hopefully give mine a clean myself, to find out if I actually need a new DPF or not. I was wondering which end you add the cleaning fluid from? and do you clean the corrugated tube bit with the cleaner as well?
I'd be really grateful for any info anyone could give me, I've found some threads about the code itself, but I can't seem to find much information on cleaning this particular DPF anywhere.
Thanks in advance.

Tip the cleaning solution in front of the rear of the DPF, otherwise you’re washing the muck further into the DPF.
Bung up all the holes before you do, or it will come out the side of the canister.
You’ll find that it will actually hold water with only a trickle coming out the other end to begin with, this trickle will increase as you was more crud out of it.
I added a few kettles worth of boiling water to the mix to begin with, not sure if there was any worthwhile method in my madness…

So far so good, if it plays up it may somehow become damaged…
It wasn’t really causing any major issues, I have a 204 with somewhat fragile turbos, I cleaned mine to reduce any unnecessary back pressure in hope the turbos don’t explode and scrap the engine.

Yeah makes sense mate. I feel we all have such a love hate relationship with these vans haha.
Cheers
