kw1281test: A Free VDS-Pro / VagTacho Alternative

[nagwych]

Hi everyone! First let me say thank you to gmenounos for putting in the work for such a useful tool! I have tried to use it to retrieve the SKC for my 04 Touareg but it's not coming through and I *think* I know why. 04 Touareg isn't on the list of cars that use CAN for diagnostics, but I believe it uses kw2027 instead of kw1281. Also, it took me a bit to figure out the ignition had to be in the on (koeo) position for it to communicate. Am I correct in thinking the cluster uses an incompatible protocol? Here is what the test said (I've shortened it up a bit though from ALL of my attempts). For all the search ninjas that might be reading this post looking for answers, I am trying to replace a faulty electronic steering lock (esl) actuator instead of replacing the entire steering column for a steering workshop fault.

Correct. As in, yes it won't work on the kw2027 protocol. There is a clue in the name of kw1281test
I am sorry that I can't offer any useful advice to help resolve your issue.

Hi, thanks so much for all the work done on this tool.

I have a 2007 VW Polo 9N. I can read the SKC out with no problems, but when I come to progam a new key it fails with a timeout when trying to log in. Is this because the SKC is incorrect?

Here is the log:

It's possible I could add support for touareg clusters. I would just need to find a cheap used one to test with.

Hi James, Do you get the same behavior with AdaptationSave instead of AdaptationTest?

 

[gw0udm]

Hi James, Do you get the same behavior with AdaptationSave instead of AdaptationTest?

Hi, yes the behaviour is exactly the same. I was using AdaptationTest I wanted to test it a few times and didn't want to cause any issues.

I've tried reading the SKC a few times and that works every time, although I've not tried anything else.

thanks!

Can you dump the EEPROM and attach it here or email it to me? (You can find my email address here)

I talked with Matt Litke of Litke Clusters and he said the SKC is only in the kessy and ECU on the touareg

Well in that case, a used cluster won't be helpful. Thanks for the info.

Thats good to know! I wonder what the kessy uses for communication protocol?

Login to the module with VCDS. It will tell you in the upper left corner which comm protocol it's using.

I've tried reading the SKC a few times and that works every time, although I've not tried anything else.

So it seems that on some Polo clusters, you need to do the adaptation on the immobilizer (Address 25) and not the cluster (Address 17) even though the immobilizer is built into the cluster and not a separate unit.

With VCDS, the instructions would be something like this: http://wiki.ross-tech.com/wiki/index.php/Immobilizer_III_Key_Matching_(Separate)
The service manual should give similar instructions.

With kw1281test, you can check the immobilizer status like this:

kw1281test.exe com1 10400 25 GroupRead 1 (you can use the up arrow key to go to the group 003 values)

You can check the number of keys matched like this:

kw1281test.exe com1 10400 25 AdaptationRead 1 sssss (where "sssss" is the SKC)

You can match additional keys like this:

kw1281test.exe com1 10400 25 AdaptationSave 1 n sssss (where "n" is the total number of keys including all old and any new ones, and "sssss" is the SKC)

You'll have to place each key (both old and new) in the ignition and switch it off and on as described in the service manual.

 

[gw0udm]

So it seems that on some Polo clusters, you need to do the adaptation on the immobilizer (Address 25) and not the cluster (Address 17) even though the immobilizer is built into the cluster and not a separate unit.

Thanks! This worked great, and now I have my new key matched!

What I found though was that if I started with the new, blank key in the ignition then I couldn't start the adaptation (came back with a NAK error). However if I put the original key in, then the adaptation worked. After taking that key out and putting the blank one in, the immobiliser light went out after a few seconds and then both of the keys worked.

So now everything is working well - thank you so much!

I am working with a 2000 NB. I have pulled the same SKC using both GetSKC and DumpMarelliMem. Sadly VCDS does not accept the SKC. I have had great succes in the past with other vehicles but this one has me stumped. Not sure if the SKC is correct and I am having some other issue not related to the SKC itself? Any suggestions?

Here it is, marelli_mem_$0C00.bin

The SKC looks correct. What are you seeing in VCDS that tells you that SKC isn't correct?

It rejects the code. I just borrowed a legit VagTacho got the same code. Tried to program within VagTacho and it also rejected the code too. Very odd. Will try a different laptop and see if I get the same results. Stumped at this point

Todd, how well do you know the vehicle history ?
Could it be that the dashpod is from a different vehicle of similar vintage, with the immobilizer functionality disabled?

 

[AndradeArt]

Hey guys,

First, I want to congratulate you on the tool, and secondly, ask for help.

I have a Polo 9N3 2006/2007. I need to extract SKC, but I can't. I have 2 cables, the blue KKL (CH340) and the VAG K+CAN, but without success in both.
I tried with the VAG K CAN COMMANDER program, VAG EEPRROM programmer and now with kw1281test. They all only read the beginning and end of the ECU, the middle is blocked.

Below is the log and attached the dump.

Hello, I had already tried with this version too and with some others, but the error is the same:

Well 0.97 is the only version that would have worked. I own one Polo cluster with a different part number (6Q0920804) but with exactly the same software version (VQMJ07LM 09.00), but apparently it's different enough from yours that the seed/key authentication doesn't work.

One final possibility is that maybe using the other version of kw1281test and the other software tools may have caused the cluster to lock you out for a certain number of minutes (similar to trying to log in with the wrong SKC multiple times). There are some measuring blocks that can tell you if you're locked out: https://www.ross-tech.com/vag-com/cars/Immo3-measuring-blocks.html
If you're locked out then you need to leave the key in the ignition for long enough that the lockout time decreases to 0. kw1281test has a "GroupRead" command that can read the measuring blocks.

If the above doesn't work then you're probably out of luck unless you have access to an EEPROM reader (e.g. https://www.aliexpress.us/item/3256804708233344.html) and are willing to disassemble the cluster to read the EEPROM directly. It will most likely be encrypted but I know how to decrypt it.

All block times are 0. Unfortunately I don't have an EEprom reader.

I've made some progress here. Follow the procedure at this link https://sites.google.com/site/imnuts/ where I can get an ECU PIN number. How he managed to log in to "25 - Immobilizer" in VCDS, but couldn't log in to "17 - Instruments". Shouldn't it be the same number since this panel is original?
Modules 17 and 25 have blocks 21 and 50 in common, can I configure a new key directly from module 25 instead of 17?

My intention is to exchange this cluster for a model that has an onboard computer 6QE920827 (Polo 2014). Connecting the new cluster and repeating the procedure above, will it return the same PIN as before, or the new one contained in the new cluster's immobilizer?
If not, how do I get the PIN for the new cluster?

Some vehicles do all immobilizer adaptation through address 17 (e.g. VW MKIV Jetta/Golf). If you try to connect to address 25, the cluster will answer and give you a message in German telling you to please use address 17.

Some vehicles have a dedicated immobilizer box that listens on address 25 (e.g. VW T4).

Some vehicles (e.g. your Polo) don't have a dedicated immobilizer box, but you connect to the cluster using address 17 for cluster functions and using address 25 for immobilizer functions. You need to adapt new keys using address 25.

My intention is to exchange this cluster for a model that has an onboard computer 6QE920827 (Polo 2014). Connecting the new cluster and repeating the procedure above, will it return the same PIN as before, or the new one contained in the new cluster's immobilizer?

Immobilizer 3 key adaptation requires the immobilizer/cluster SKC and the Engine ECU SKC. Assuming that the Polo 2014 cluster is even compatible with your vehicle, you'll need to know its SKC and then pair it with the ECU before you can match your keys.

Well, I only got the SKC from the ECU/IMMO (address 01/25), but that didn't work on the current cluster (address 17). My fear is that I will buy this new cluster and also not be able to extract the SKC from it.
Do you know if kw1281test works on cluster 6QE920827 (Polo 2014)?

 

[gmenounos]

No idea. If you really need the SKC and none of the tools work, get an EEPROM burner and I may be able to help.

Hello. I bought the cluster, but without success extracting the PIN either, same message as before ("Unable to determine SKC."). The software version is different "VQMJ09HH".
At first I will try to disable IMMO to be able to start the car with this panel.

It is suggested for future versions to include this software.

Thank you very much for your attention.

I would like to enable the closing and opening of the windows by remote control, but I don't understand how to do it. it only does it if I insert the key into the door and keep it turned to open or close. With vcds I don't have any adaptive function in the comfort control unit, reading online I read that vds pro was needed to modify the bios.... but I didn't understand anything. Then I got here and read this post. Can you help me add this functionality? Thank you
