DPF for Audi A3 CAYC - Diesel Particulate Filter

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 loading data? MSG? What 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 175ml.

The best place to look is in the MSG (Message Summary) within the list of extended data. For example, in my CBBB (Car Battery Battery Booster), it's located in MWB 108.

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

When is this scheduled? Mileage?

When it is full. With VCDS, you can read out the ash mass or ash volume. Please do not confuse this with the fill level.
The value essentially depends on...
- Fuel consumption,
- Fuel quality,
- low-ash engine oil (therefore, please do not experiment, but use a low-ash oil that is also suitable for the engine).
- Oil consumption.

You can feel free to post your scores in the linked topic, where you can also find some reference values: https://community.dieselschrauber.org/en/viewtopic.php?t=24222

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

That is, half full...}

I would also say that.

... and also matches the mileage.
