Hello,

I have a few questions regarding the diesel particulate filter in the...

AUDI A3 TDI, 1.6L engine, 77kW, 7-speed DSG transmission.
MKB: CAYC

Does the DPF need to be replaced or cleaned at some point?
Wann ist dies vorgesehen? Mileage?
Can I read the load value? Is it an MSG? What is the value? (VCDS is available).

Thank you for the information.

Hi,

der DPF muss getauscht oder gespült werden, wenn das Aschevolumen einen vorgegebenen Grenzwert erreicht. Der liegt bei 4-ZYl. CR often at 175 ml.

The best place to look for it is in the MSG (Message Summary) within the list of extended data fields. For example, on my CBBB device, it's located in field MWB 108.

The threshold value applicable to your engine will be displayed when you hover over it with the mouse. For a healthy engine, mileage of 200,000 km or more is typically achievable.

Wann ist dies vorgesehen? KM-Stand?

Wenn er voll ist. icon_cool.gif Mit VCDS kannst Du Aschemasse oder Aschevolumen auslesen. Bitte nicht mit dem Beladungsgrad verwechseln.
Der Wert hängt im Wesentlichen ab von...
- Kraftstoffverbrauch,
- Kraftstoffqualität,
- aschearmen Motoröl (daher bitte keine Experimente sondern ein aschearmes Öl hinein, welches auch in den Motor gehört),
- Ölverbrauch.

Du kannst Deine Werte gerne im verlinkten Thema posten, hier findest Du auch Anhaltswerte: https://community.dieselschrauber.org/en/viewtopic.php?t=24222

Viele Grüße, Rainer

Hello,

I've done a little reading.
Which values would be relevant?

Ich denke mal 35g und 70g, oder ? D.h. Half full...?
KMSTand = 120,000 km

MW257 DPF Oil Ash Content: 35g
MW259 DPF mass calculated: 10.94g
MW260 DPF soot mass measured: -3.15g.
MW262 DPF Maximum Value!? 70g

I would also say that.
