Thanks gmenounos - 9600 baud worked immediately and pulled the SKC! You really have talent. I should have the new key in a week and will try the adaptation save. Thank you again.

This is an amazing thread. Man, could we have used this years ago.
Looking forward to actually using it (NOT), good to know I can do it.
I have a question-Does the standard Ross Tech cable work for this?

gmenounos - my duplicate key arrived. I would appreciate confirming syntax and steps so I do not screw something up. I keep getting smarter the through experience with this car. Which is really painful. :). I read through all pages in this string and the wiki. I did not find a complete step-by-step. I also watched the Ross-Tech immobilizer / key video and pieced the below together. If you think the below is of use to others, I'll post it in the Wiki once confirmed.

SYNTAX: kw1281test.exe com3 9600 17 AdaptationSave 21 2 07268
In the above: 17 is the instrument module; 21 is the channel; 2 is the number of keys (existing plus the new one); 07268 is the SKC

My big question is on the # of keys. I just took possession of the car with one key. I have no idea how many original keys exist. My understanding is the history of keys does not matter and that the # of keys in the argument above is the number that I am programming now and will work going forward. Any earlier programmed keys not included now will no longer work. The immobilizer chip in the original key continues to operate. Correct? I don't want to lose my original key functionality by accident. BTW - I successfully programmed the fob function using the door lock method.

Execution Steps:
1) Insert key #1 (new key) in the ignition, turned to "on" with the engine off. The immobilizer light is on.
2) Run "AdaptationSave" command
3) Immobilizer light turns off when adapted
4) Remove Key
5) Insert key #2 (existing key) in the ignition and turn to "on". The immobilizer light should be on. Being the last key, the light should blink once then turn off.
6) Remove key from ignition
7) Remove Cable
8) All keys should now start the car

Thank you very much.

Yes, that looks correct.

ADDITIONAL INFO:
During the "Receiving ACK", the Instrument Cluster chimed and reacted with the gauges sweeping and the lights changing. Communication was definitely established so some progress.

QUESTION:
Any idea or thoughts on the timeout? Perhaps user error?

Unfortunately kw1281test doesn't work with that particular TT cluster. Someone sent me one as a donation and I've tried to make it work but so far have no luck even though it's very similar to the Beetle clusters internally. I even tried a couple commercial tools that are supposed to work with TT clusters and neither could pull the SKC from the one I have.

Thank you gmenounos! Appreciate the feedback.

If you or anyone else have any ideas, I'm all ears.
Also, if I can help contribute to further the development of kw1281test, don't hesitate to ask.

Good afternoon everyone,
One more success case !
Was a bit confused in the beginning because it was asking me about cluster being in new mode (4) , but after a bit of carefull reading, was easy.

I just wanted to thank you for this amazing tool!

So since this does adaptation saves, is it possible for me to code my car from auto to manual transmission? The guy who did the swap forgot about that part.

Hi!
What do you mean ?
I know that by vcds you can change the softcoding in the Engine part from 1 ( automatic ) 2 ( manual ) and 3 ( 4x4 )

That would be done using the SetSoftwareCoding command in kw1281test. You'll have to research what the correct soft coding is for manual transmission.

I know the correct bits are 1 for auto & 2 for manual. Thanks @alegria1999 for the info on 4x4. I don't think I've ever run across that. I'll definitely be looking into this further.

You can try to adjust the time setting of the driver in the computer management. I had the same problem, a medium setting in the dropdown menu worked.

Hi All,
well done for job and support you are doing.
Does anyone succeed to sort this out"Caught: System.InvalidOperationException Controller did not wake up."
I tried with latest version with two different bands 10400 and 9600 but both with the same result

and also tried kw1281test COM3 10400 17 DumpRBxMemOdd 66560 1024

but again Controller did not wake up.

what I am doing so wrong? Dongle is vag kkl 409.1 with WIN10, drivers installed correctly. Tying to get SKC from VW Tauran 1.9TDi Instrument cluster is VDD.

thank you for your help

Sorry, it looks like the Touran uses CAN bus diagnostics, so kw1281test won't work with it.

I just added a new item to the Q&A on page one 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.

First off, thanks so much @gmenounos for this amazing tool.

I had a Mk4 GTI in high school and managed to pick up a non-running one a couple weeks ago to turn into a track car. Thanks to this tool, I was able to make some duplicate keys using my MacBook and a cheap FTDI cable. I updated the kw1281test wiki with some details on the cable and instructions I used -- hopefully someone finds that useful in the future.

Now that I have the car running, I want to get it registered and smogged. After a drive cycle, I have all of the monitors ready except for the Evap System and the Secondary Air System. It looks like both VCDS and the Snap-on tool can force these tests to run. Evap is Basic Settings Block 70; Secondary air is Basic Settings Block 77.

Is it possible to initiate these tests using kw1281test? Would something like this work for the secondary air test:
  1. Turn the car on
  2. Let the car idle
  3. Attach FTDI cable from Mac to OBD2 port
  4. Enter ./kw1281test 12345678 10400 1 BasicSetting 77 into Terminal
  5. Profit?

That should work. I've personally only tried BasicSetting on a TDI but it should work the same on other MK4 ECUs.. And thanks for adding to the wiki.

Thanks so much. Unfortunately, I haven't been able to get it to work and I'm not sure why. Running the command reads the block and outputs it to the terminal, but I don't I see any other feedback about the test itself. It appears to do *something* because it locks the engine RPMs to idle until I quit, but the monitors still aren't ready. Are there logs I can check to see if running the test succeeded or failed? Maybe a more verbose mode?

I've been at it for hours and hours, and the closest I get on my 2000 VR6 Jetta to pulling the SKC is this, over and over. The interface is the VIMVIP KKL 409.1 you linked in your FAQ. The driver is the one also linked on your FAQ. I am using a USB-C to USB adapter. The command prompt is able to show the device and its baud rate, and can show "connect" with an "su" prompt. Though often it shows "line is busy" and I have to killl a process first. Anyway...

It pauses a bit at "reading sync byte", then retries. I've noticed that if I try a couple times and sit here for a minute with the cable still plugged in, the immobilizer light starts flashing. I then turn off the key and that clears it.

But I would love some guidance on what to do next (getting close to renting the VAG-TACHO but still hopeful!)

The interface is the VIMVIP KKL 409.1 you linked in your FAQ.
That VIMVIP KKL cable only works with Windows, which is noted in the instructions. I updated the wiki last week with a link to a cable that will work on Mac/Linux and full macOS instructions.

See if you can return that cable, buy the one with the FTDI chipset, and follow the instructions I added to the wiki. I’m pretty confident that should do the trick. If you’re still having trouble, I’m happy to help.

Update: Just saw your profile. Are you in Los Angeles? If so, I’d be more than happy to meet up and help if you can’t sort it out.

Thanks very much for that quick update! Though I will be back in LA Aug 22nd, the car in question is actually in St. Louis, but thank you for that offer!

I've ordered the correct cable. Unfortunately I was working from the first post in this thread and not the wiki for information, and the link there took me to the other cable.

Will the fact I'm using a USB-C to multiport adapter throw a wrench into this whole thing?

Alternately, is there a version of your software floating around that's compatible with XP, which would allow me to use the cable I have right now with an old laptop running XP that still seems to work?

The adapter shouldn’t cause a problem. I used one on my MacBook.

As for Windows XP, I’m really not sure. This isn’t my work — all credit goes to @gmenounos — I just try to be helpful. I think you can install Windows 10/11 and run it unregistered without any limitations that would impact kw1281test.

Thank you @gmenounos for this amazing tool!

I am rescuing a 2004 NBC and I only have one working key... I have HEX-V2 but I was able to use this cheap KKL 409.1 cable from Amazon to get the SKC: https://www.amazon.com/dp/B00K6498D0?psc=1&ref=ppx_yo2ov_dt_b_product_details

I used these drivers successfully with that cable: https://learn.sparkfun.com/tutorials/how-to-install-ch340-drivers/all

Initially, it wasn't working for me:

Caught: System.TimeoutException The operation has timed out.
Unhandled exception: System.TimeoutException: The operation has timed out.

I changed a setting in on the COM port driver, and got it working with a caveat. I had to periodically unplug and plug the USB cable end in. So, there is still some issue, but it got me to where I needed to be! I got the code!

Hi all. I've been trying to read this thread to see if I can get anywhere. lol I'm new to this so I apologize if I'm asking something thats been answered already.
Is there a free software that I can use for my 2014 VW Passat TDI to change programming?
Specifically I am looking to turn off the automatic locking feature on the car. The auto-lock feature is the one that locks the door at 16kmph (10mph)
. Right now
I've looked at VCDS from ross-tech but am told there is a free option? If VCDS is my only option what is the recommended cord?

Am I barking up the wrong tree?

Thanks from Toronto!!

Cheers

I installed Windows 10 on an old laptop and succeeded in pulling the SKG! Thank you!

But I ran into unusual trouble in adapting keys. There were preciously 3 keys, and I changed that value to 2 for the two keys I have. After I saved the new value, the number 2 became a 1, without me changing it.

When I try to use that key I get the flashing immobilizer light and an error 01179 - Incorrect Key Programming.

I clear it by doing the process again but choosing just 1 key. Am I doing something wrong? Anything sound familiar?

Often you have to remove all the keys (enter 0) for the number of keys, SAVE, then go back in and enter the actual number of keys you have. And as the instructions say, be sure to have them all at hand, as you have only a minute to get them matched.

Well I performed the procedure with the "0" save for numbers of keys, and I still have a car that doesn't want me to have more than one key. I've pulled the battery cable as a Hail Mary reset, but I'm not very optimistic about it. I've gotten an occasional code about a weak signal but not every time. I select 0, save, enter 2 keys, save, and it flashes 0 very briefly, then drops down to 1. This throws the "01179 - Incorrect Key Programming", and flashing immobilizer light even after removing the key and reinserting it. It does run the car, but the light flashes. I then go back into VCDS (old Vag-Com 311.2-N) and perform the procedure again, but only select one key, and it's happy with that. Any ideas what's going on here?

If I take another key which is not coded, can I code THAT key to the car and try this, or do I have to start with a key that's already coded?

Used to be three keys, but now only two...have the keys been used on a different car before?
You have to use a "never paired to a car before" key (there's a "write-once" little RFID thingy in the key-blade portion of the key). If a key was previously paired to that car, though, it should work.
