In the article about LLMs, it states:
Quote:

In some TDIs, the soot limit is not calculated based on the mass airflow sensor (MAF) value, but rather based on the boost pressure.

So far, my search has only revealed these two manufacturers of 3-cylinder engines: AMF and BAY.
Which other ICD codes are relevant?

Thank you for the responses.

Best regards, Klaus.

Hello Klaus,
You can't necessarily attribute that to the MKB. For example, there are also ASZ or AXR that do that.
have. For example, you can find them with all the numbers "038 908 019 N?". "Luck" is definitely involved (there are many of them).
Specifically, I haven't checked that.

Best regards, Micha.

Definitely 1T!

The engine didn't have a mass airflow sensor at all icon_razz.gif.

However, the underlying program files are likely to have disappeared into the mists of history icon_rolleyes.gif.
