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
