You will want the real full vcds for any coding. You cannot use vcds to delete the immobilizer, but can use it to program the immobilizer after pulling the skc with this software.
Sometimes you can get the old unlimited vin ones on eBay for cheaper, just make sure its a real one, or itll be a paperweight that doesn't even hold paper down well...

kw1281test can delete the immobilzer, and if you're really on a budget it can do coding, adaptation and basic setting (for adjusting the injection pump after a timing belt change), but it doesn't tell you what the coding and adaptation values mean so you'd have to have the factory service manual. And it's not nearly as easy to set up and use as VCDS.

I know this isn’t a question for this thread but what is the purpose of adjusting the pump after the timing belt change?

Why would the timing be changed though does it get moved in the process of changing the belt, sorry if this is a dumb question I’m still learning

Yes when you do the timing belt the pump gets pinned at it's "base" setting, and then needs to be fine tuned afterwards.

Anyone know why I am getting "COM1" is not in correct format? using a ross-tech hex-can (not v2), already have the vcp port setup, and vcds is set to intelligent mode off. Trying to pull the SKC on my 2008 A4, I know its possible on a rb4 cluster. wanted to try procedure on rb8.

Been riding the struggle bus for weeks now, hoping to hop off soon. anyhelp would be appreciated, tried a bunch of other programs, vag eeprom, vag k command, VM machines (win xp, 8), nefmoto eprom tool. the whole lot.

Anyways, here's my script... Thanks in advance

You have put KW1281Test as an input parameter, try this instead :

C:\Users\Misha\Desktop\kw1281test_0.97.0-beta_Win10\kw1281test.exe COM1 10400 17 ToggleRB8Mode
(Here is what you typed, can you see the difference? :

I don't think it's going to work with your car anyway. Supposedly the 2008 A4 doesn't use the K-line for diagnostics. See the first post of this thread:

Q: Will it work with my car?
A: kw1281test works with many VW group cars that use the K-Line for diagnostics. It's been most heavily tested on the VW MKIV Golf/Jetta/Beetle. It will not work on cars that use CAN bus diagnostics such as those listed here.

Hello! I have an airbag light on for my seat belt connector, and I just had my ABS light come on. I know I’ve read the Airbag controller before, but now all I get is a timed out error and saying it couldn’t connect. I’ve tried 2 different baud rates and not sure what the issue might be. Other modules (cluster and engine) work fine. The ABS codes are stored in the airbag module correct?

Edit: I tried 10400 again and updated to the latest and it worked 🤦🏻‍♂️.

That only read the airbag module tho… seems the ABS codes stored somewhere else.

Edit 2: I've answered my own question again with a little more research, and see that the ABS is module 3. But here's about where I'm at a dead end. I get Caught: System.InvalidOperationException Expected KWP1281 protocol. Which the only mention of this on the internet seems to be the error handling in your source code. Is the ABS module not readable? Full log:

Was just going through some of the updates on Github and saw that a number of revisions back there was a note for fixing "GetSKC" command for EDC15 ECUs.

I take it to mean you can extract immo SKCs from the ECU, not just the cluster, then? Does it also work for the period ME7 gas ECUs? EDC16 BEWs and BHWs?

I at least have a BHW I can try it on. A co-worker has a later Jetta GLI 1.8T I could also probably mess with to confirm if it works or not.

Hello gmenounos and everyone on the forum !
I tried to get the SKC code from a D06 8L0920932M (Jager) cluster . The kw1281test program recognized the cluster but unfortunatly did not show the SKC . The cluster used to be connected with a me7.5 ECU in the car . I benchtested the cluster and the ECU for the code separately . The car getting a "new" VDO cluster . What would be the right way to get the SKC ?

It seems that the airbag uses KW2000 protocol and not KW1281. I can add support for that, but not sure how soon.

Currently only works for EDC15 ECUs. I have an EDC16 ECU that someone gave me, so there's a chance I could get it working for that. ME7 but I don't have one to test with.

Try the following commands and report whether either of them works:

kw1281test.exe COM2 9600 17 DumpMarelliMem 14336 2048
kw1281test.exe COM2 9600 17 DumpMarelliMem 3072 1024

kw1281test doesn't support ME7.5 ECUs, so you're only going to be able to get the SKC from the cluster.

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.

I tried on my 2004 touareg as well, and wasn't able to get it to work either, though I hadn't updated my software.

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:

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)

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

I may be able to find something to donate.

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

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