WIV-daten beim Polo 9N 2004 | Posts 16+

I have no idea, but you definitely have the training manual for the Skoda combination instruments, right?

Um... japs :oops.

And I'm documenting everything as well...

I am sorry, I cannot access external websites or specific files online. Therefore, I am unable to translate the text from the provided URL.

P.S.: The Golf 5 now has that issue too...

*edit*

I also missed the [url=de.openobd.org/vw/polo_9n.htm#17]Polo match.

Great

I'm going to create a label file for the AI soon.

Are you interested in having it for the download section on your website?

Okay, but I'm going to modify it further to cover all instrument clusters in the Polo/Fabia. But the preliminary work is already helpful.

It's mostly done (I just made some time for it).

However, I'm still unable to make sense of MWB 6 and 7.

Extracted values 006:
10.0 mm / 12.0 mm / 10.5 mm / Open

Extracted values 007:
56.0 mm (extending to 56.5 mm) / N/A / N/A / N/A

"Open" apparently refers to the hood contact sensor, and it cleverly indicates the opposite: "Open" when the hood is closed, and "Closed" when the hood is open.

But what do these mm specifications mean

That should help .

Wow, thank you .

Do you happen to have any more information about the MWB 007?

Okay, bitte gib mir den Text, den du übersetzt haben möchtest.

Thank you... but somehow, my values in fields 006 and 007 don't seem to match.

006 = approximately 11 mm, 007 = approximately 56 mm.
So, a difference of over 4 cm (!).

In my opinion, this also cannot be explained by the oil level readings when the engine is running or stationary.

Could 007 possibly refer to the coolant level?

Okay, let's do this right this time!

Aha, that makes sense again .
-> Level ~ 5 cm, deviation ~ 1 cm.

Now, I'm only interested in knowing what reference value the oil level deviation is based on.

If an average value for the WI (presumably a specific metric) is being calculated, then a large number of measurements must be taken, for example, per trip.
So, is the deviation referring to the difference per engine cycle, i.e., between the level at the start (=reference value) and the minimum level during the subsequent drive, when the oil is distributed in the engine?

Good question .

No, seriously, I have no idea, but I'm just glad I have something to say about it .

Just observe for a moment...

I would assume that the value is also based on the last 100 kilometers, just like the average.

The target value should correspond to the oil level range indicated by your dipstick. Unfortunately, I don't have any target values for this, but in principle, it can be tested.
After changing the oil, fill it up to the lower mark and note that value. Then, fill it up to the maximum mark and note that value as well. This way, you'll have both the minimum and maximum levels. Then you'll know what the maximum allowable deviation can be.

Ah, yes, I hadn't quite internalized the concept of the "last 100 km" just yet...

Normally, you shouldn't see any measurable oil consumption over 100 km, let alone something around 1 cm.

Based on the ~1 cm difference between the minimum and maximum readings on the dipstick, which likely corresponds to the amount of oil "pumped" during engine operation, I initially assume that the oil level deviation displayed is actually the difference between the starting level and the lowest level reached during the subsequent drive.

And in the AI, the corresponding minimum and maximum values of this difference are stored.

Apparently, this only applies to the last 100 kilometers of the journey, because:
If you then drive more than 100 km continuously, the difference should approach zero over the last 100 km, since the reading at the beginning of the measurement interval is already as low (engine running!) as it is when the vehicle is parked.

During my internship, I occasionally had experiences like that. If those values were still stored, the minimum value (6.1) would have to be significantly lower than 10.5 mm.

However, the last 100 km were divided into several trips, so the full fuel level should have been recorded for each trip. That would explain my values in the MWB 6.

How do I get this information into the online label for MWB 6...?

And: If my theory about the significance of these values is correct, what practical value would this data have in the context of an inspection?

Just send me what you have, and I'll take care of the rest.

'None, I think that's only useful for investigations related to engine damage, etc.'

In none of the VAS procedures I have seen so far was this measurement value read out, or was there any indication of it.

OK, it's on its way.

Okay, I've refined it a bit and also prepared it for the Fabia.

Adaptation and some of the coding are also included, but it will be fully completed eventually.

Otherwise, VAG-COM 405.0 or higher is required, meaning the current version 409.0 is a prerequisite. However, if the label file (6x0-920-xxx.lbl) is renamed, older versions should also work with it.

Wow, it has become a really big thing .

What about the Ibiza 6L as a third option? Car on the Polo/Fabia platform?

Does the label file not fit there?
