Isn't the CCM address 46 not 45?

yes, I typoed the post here but 46 is what went into command line

Hey Guys, I'm trying to retrieve my SKC code for my Golf City 2007 (Canada) in order to do a key adaptation. I've tried a couple times but I get a timeout period expired error.

 

[Kalmurn]

Well Im happy to report that I was able to get it to work successfully with a friends cheap obd2-USB cable functioning as a COM port. I was able to get my SKC code and using that SKC code i was able to program another key using VCDS.

I already have the "windows roll up and down function with the key fob buttons enabled using Motordiag Komfort Manager Lite 1.20 (Details here for how to do this) so now I need to figure out what else i want to do with kw1281test! Many thanks to all of your work on this project!

Some additional info for anyone attempting to use the SKC code to program a new key.
I was initially trying some other ways of potentially disabling the immobilizer as well as programing the key but nothing was working. I was getting the word "FAIL" where the trip meter was in the bottom right corner. I also got this when I was attempting to login in for adaptation with VCDS and also when attempting to use the adaptation function of kw1281test which would cause it to error out with a timeout. This was because the immobilizer had been triggered and there was a countdown timer in the cluster preventing login. If you go to the instuments section of VCDS and view measuring block 24. If the first field is greater than 0 you will not be able to log in with VCDS and im assuming this was also preventing the use of kw1281test from logging in for adaptation settings. Some more detail here

 

[AJ_27]

Success, I was able to retrieve my SKC code for my City Golf 2007 and adapt my new key using VCDS (Hex+Can cord). I was getting a timeout period expired problem. I was playing around in the options and I unchecked the "Boot in intelligent mode" and I believe I checked the " Bypass Can Init" box and it worked.

Thanks to gmenounos your program and this awesome forum saved my car. Some kids broke into my apartment on boxing day and stole all my car keys amongst other things. Living in the Canadian Sub-artic made this situation particularly ****ty with no Volks dealership or capable locksmith where I live ( Yellowknife ). I was looking at a 2000$+ tow to closest dealership (Edmonton).

I hope you deactivated the stolen key in Vagcom.

Great to hear this works on Mk5's too.

Programming new keys automatically erases any previously programmed keys. Also, City Golfs and City Jettas are not Mk5s, they're more like a facelifted Mk4 sold in Canada, Mexico, and some other markets. They're basically identical to the last Mk4s but with different bumpers, fenders, headlights, taillights, and in the case of the City Jetta, trunks.

To anyone reporting "Controller did not wake up." errors, please include info about what kind of cable you're using. kw1281test reports some info about your setup in its log, but it doesn't know anything about your particular cable other than what COM port it's configured as. I'll add some more troubleshooting info to the error message and write up some documentation when I get time.

 

[Joe De Guy]

Hi, new to the forum. Have the cable, ran the script and i was able to pull my SKC digits. But when I go to login with my VCDS it doesn't recognize the SKC. Am I missing a step somewhere?

It suggests checking measuring block 024 to see if your cluster has locked you out for a certain amount of time.

 

[Joe De Guy]

Thanks, figured it out. I was logging into Immobilizer rather than instrument 17. When I logged in there everything else flowed, Thanks for the quick help, much appreciated.

Wanting to do some cluster mods on a 2003 Jetta. Was thinking of adding fis. I would love a color one but they seem to be difficult to get. Is there any vehicles they can be salvaged from or clusters that can be used? I have a half display Passat cluster I can modify if I can’t do the color. I am on the lookout for the full size display.

Color LCDs never came factory in a Mk4-compatible cluster. Full size mostly only sold in Europe. I think the only exception in North America was the W8 Passat.

I've got a w8 cluster if you want one of them. The color mfa didn't come on any of the USA vehicles stock that I know of. Clustersbylitke does the conversions for those, but its not cheap.
I also have sport tdi faces to do the w8 conversion.

From ELSA program i have found the following :

I don't see the K-Line listed. If you look in ELSA, does the OBD-II diagnostic connector have a K-Line? If so, where does it go? Is there some external CAN-gateway that converts the K-Line signal to the CAN bus and routes it to the cluster?

kw1281test only works if the car supports K-line-based diagnostics.

Hello again and sorry for the delay. Here is the wiring from the Czech service manual of Škoda Fabia, description is much the same as himtan posted. Unfortunately there is absolutely nothing about "K-Line" in the manual.

A 2008 Jetta uses CAN bus for diagnostics, not K-Line (source: https://www.ross-tech.com/vcds/canbus.php) so kw1281test isn't going to work for you. Sorry.

 

[Nawalski]

Thanks for your prompt reply and your extensive knowledge, would you have any suggestions for this model to obtain the SKC?

 

[krstecd]

Q: What is kw1281test?
A: It's a program I wrote in 2020 to help TDI VW VAG owners retrieve their vehicle's SKC and program their CCMs using a generic KKL cable that you can probably pick up for $20 or so. It runs on Windows 10/11, macOS and Linux. It's open source so you can copy it, modify it or just read through the source code to understand how it works. But it's a command line program and only works with cars that support diagnostics via the K-Line. For VWs, this means only MKIV cars are supported.

Can i somehow get my SKC code on my Golf 5 1.9TDI Goal 2006? Is this gonna work?
I tried to run vag can commander on my HEX USB cable with tmega162 IC that i bought from aliexpress but i cant get it to work.

Sorry, it won't work with the Golf 5 or any other car that uses the CAN bus for diagnostics: https://www.ross-tech.com/vcds/canbus.php

Any other solution to retrieve my SKC code without buying other cables?
i also can borrow a Delphi DS150E cable from my neighbour, any way that i can use it to get the SKC?

Not that I know of. I only have MK4 cars so I don't know how to add support for anything newer (which would also require a different cable).
