WIV data for the Polo 9N 2004

Hello,

in
Okay, I'm ready. Please provide the German text you want me to translate.
The following describes information related to various vehicles (WIV).

Unfortunately, things are quite different with my Polo.
It starts with the channels in the AI: channels 43 to 45 are not assigned on my system.
Most likely, their content can be found on other channels of MWB 12 to 16.

Here are the data that were read out today.
Please note the digits 40 to 48, which have values of 1 or 3, respectively. Could these be offset WIV channels?

MWB: Value 1 / Value 2 / Value 3 / Value 4

012: 40 / 76 / 41 / 224

013: 42 / 150 / 43 / 500

014: 44 / 730 / 49 / 365

015: 45 / 2.0 / 46 / 0

016: 47 / 118 / 48 / 41

At least the values for 43 and 44 make sense, according to the above. Technical article.

The remaining mileage + time until the next service (currently 24600 km / 319 days) doesn't seem to be displayed anywhere...

Whoever can decipher more data -> please post

Thank you!

Hi Ulf, did you read out the measurement data block 08 (MWB)? Or, when adjusting -10 WIV, you should normally be able to see channel 40-45. Here's the translation:

40: Actual kilometers driven.
41: Actual number of days.
42: Target minimum kilometers.
43: Maximum kilometers.
44: Target number of days.
45: Value 1-4 for WIV setting (where 1 = fixed service, 2 = Longlife gasoline engine, 3 = Longlife V6 engine, 4 = Longlife diesel engine).

Ah, that might be a bug -> I read the data (as usual) normally, not in "adjust" mode.

I'll try adjusting it tomorrow.

Do you need a login code for this, like you do for the engine?

Would the 2.0 behind the 45 (see above) for gasoline engines, indicating "Longlife," then be a factory miscalibration?

Hi Ulf,

Normally, it should be encoded as 4, but it's best to first check the settings to see if the values are the same there. To postpone the service, you need to go to channel 02.
'Enter the value zero and save. Then, the data in channels 40 and 41 will be reset to zero!' You should note that the remaining time is calculated differently there.
It's time to start the countdown! So, begin counting upwards from zero. You can no longer see the remaining time on the 'Longlife' indicator, as the time is calculated by the engine control unit, and several factors can influence whether you reach the full 'Longlife' duration or if it expires sooner (e.g., frequent short trips, oil level within the normal range as indicated by the oil sensor).

-> Channel 45 (oil quality)

1 - fixed maintenance interval
2 - Flexible maintenance interval

Hmm... that doesn't necessarily contradict the article here.

2 = flexible gasoline-powered
4 = flexible Diesel (which would then be missing from your website?)

Regarding the 9N, I haven't found anything about '4' yet.

Speak, because there's only 1 and 2 there. As far as I'm aware, so far.

Okay, then the information "Otto or Diesel" must be firmly programmed into the AI, and it could be linked to, for example, the engine speed range.

From this perspective, one might even wonder why it would be possible to set a diesel engine control unit to "Otto-Longlife" mode (and vice versa) in other vehicles.

Ah, then the information 'Otto or Diesel' would have to be firmly programmed into the AI, which could, for example, be linked to the RPM range.

Yes, that's because, as you already mentioned, the software needs to target the DZM.

From this perspective, one might even wonder why it would be possible to set a diesel maintenance interval on a gasoline longlife engine (and vice versa) in other vehicles...

Good question, although I've only ever found two options on some newer diesel vehicles as well...

Okay, so I explored the "Customize" feature of my AI today.

Kindly, you even receive the meaning of the individual channels (where available) in plain text .

Compared to Theresias' updated list on his website (thank you ), I have found the following discrepancies:

Consumption adjustment (03) is not available for me.

Channel 47 = Amount of soot in the oil after 100 km.

Channel 48 = Thermal stress on the oil at 100 km.

Channel 49 = minimum days until service (365).

Channel 35 = 0, Channel 39 = 1, Channel 50 = 32000, with no apparent explanations provided for any of these values.

In measurement block 005 (=read), you will see the remaining kilometers (x 100) and days until the next service displayed – the same values as you would get by querying the instrument cluster using the reset button.

I had completely forgotten something.

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

I think everything should be included now.

P.S.: The mileage display (or its modification) was removed in many VW models for the 2003 model year.

P.P.S.: It's about time someone created a label file for the 9N AI models... Could you send me a list of the available measurement blocks and their values?

Hi everyone,

I just checked again, and for the newer ones, there's only channel 1 and channel 2 available on channel 45.

I have a Golf from 2002, and it shows a reading of 1-4 on channel 45.

Okay, so '1 starr' is correct.

2. Flexible interval.

Best regards,
Pepps.

Channel 39 = 1, Channel 50 = 32000

'39 has appeared for me a few times now, but it hasn't been documented anywhere, and it's not even taken into account in AI trading.'

'KANEL 50' is a known code and is used to initialize the immobilizer. The '32000' value is simply a type of checksum or is used to overwrite the entered login.

Channel 35 / 39, with no discernible explanations provided.


For us, 35 is the RPM threshold for the oil pressure warning, but only when the RPMs are increasing. The default setting is 1500 RPM.

'TOG Sensor is turned on or off' (this is the oil level sensor).

@theresias
Are you also unable to read all of your files, what?

CU Gremlin.

Regarding point 35, I've already written something about it above.

But had I ever documented the number 39 before?! *pondering*

But had I ever documented the 39 before?! *pondering*

I have no idea, but you definitely have that training manual for the Skoda instrument panels, right?
