Hello!

Does anyone know the meaning of the measurement data blocks in the climate control unit?
What is the translation of "meines 1.9 TDI AVF (Audi A6 Bj.11/2001)?"

best regards

wvg

Hi,

Please always include the VAG part number in such cases; it greatly simplifies the work.

Best regards, Rainer.

Hi,

Save the file.
http://www.ross-tech.com/vag-com/download/label-files/4A0-820-043.lbl or
http://download.openobd.org/labelfiles/german/8L0-820-043-1D.lbl or
http://download.openobd.org/labelfiles/german/8L0-820-043-2D.lbl

under the name '4B0-820-043-AC.lbl' in your VAG-COM label directory.
Feedback regarding the plausibility of the measurement value labels is desired icon_smile.gif.
Does this device have one or two displays?

Sebastian can probably tell you more about that.

Best regards, Rainer.

Hi!

Thank you!

The control panel has a temperature display for both the left and right sides.
In the middle, the blower speed setting is displayed again.

best regards

wvg


Can you perhaps help me solve my problem?

My issue is described under "General Technology" (see WVG).

Hi!

Hier ein Feedback bzgl. der Plausibilität der Label^s. Unfortunately.
In none of the label files are the displayed values plausible. icon_cry.gif

Do you perhaps have a few more of those?

Neither 4A0-820-043.lbl, nor 8L0-820-043-1D.lbl, nor 8L0-820-043-2D.lbl fit even remotely to this questionable control unit. Perhaps next time, instead of making random guesses, simply refer to the relevant guides, as this is more likely to yield a correct result.

They also can't, because none of the control units for which files were mentioned have any connection to the one installed in your car. A control unit from an A4 (8E) would be similar up to manufacturing date 006, but after that, the values are shifted by -1, so it's not a real solution either.

You don't necessarily need "a few" other options; it's enough to have the right one, or to be able to recognize what works and what doesn't. This depends on which VAG-COM version you are using, so it would be helpful if you could provide the version number. If you are using a current version 512.x, there is a solution for your problem. However, if you are using an older version (e.g., 409.1, which was the version as of September 2004), you need to be careful, as these represent an older development stage and are no longer supported, especially regarding the "documentation." Even if data (e.g., label files) from newer versions can be made to work with them (e.g., by renaming), there is no guarantee of the accuracy or completeness of the displayed data.

Hello!

Thank you for the explanations icon_idea.gif.

I'll probably have to get a newer version eventually.

Currently, my problem with the label files has been resolved.

Yesterday, I noticed that my compressor is stuck.

Best regards,

wvg
