kw1281test: A Free VDS-Pro / VagTacho Alternative

[gmenounos]

Hi I'm hoping to get some help. After such a long time finding the right combo of laptop, KKL connector, and kw1281test, it looks like I got really close to getting my SKC, but it keeps timing out before sending the code. Now I can't even run the program anymore as it says 'access denied' and my computer says to 'find the right program for this pc'

Can anyone let me know whats I'm doing wrong? It seems like its connecting as my car ends up beeping like I just turned it on when it starts to run, then it keeps timing out. Then I try running the code a few more times and now I can't even run the program anymore.

I have no idea why you can't run the program anymore. Try downloading it again.

Try disconnecting the battery from the car for a minute, then reconnect and try the GetSKC command again.

If that doesn't work, disconnect the battery for a minute and then try the following command and see if it works:

FWIW, to close the loop on my original issue. Was tinkering with the interface circuit using the LM339 and 2222s Sparkfun put on there but decided the best way was to do it right to eliminate variables.

Ended up just buying a cable. On Amazon it's the red one, says "2 real 9241A Chips" in the listing.

https://www.amazon.com/dp/B0BZCC9FTL

I opened and verified the chips are marked 9241A and it also has the FTDI FT232RL in it. Are they legitimate or fakes? Always a risk with something like this but no way to know that for certain. To be honest the quality seems pretty decent to me, I have no concerns.

The 9241A is a purpose built automotive transceiver, similar to, if not perhaps even the same, as what VW put in the ECU on the other end of the line.

Worked like a champ so far, even works fine with the Mac. But I have only read back the SKC, not tried programming keys with it.

Question about the door remote, not the immobilizer. It appears the sensor in my door isn't working so using the turn key in door, hold for 10 seconds and press the unlock button method doesn't seem to work (the little alarm armed LED next to the door lock doesn't blink, which would seem to confirm this).

I've seen reference to using the AdaptationSave command to the CCM

kw1281test: A Free VDS-Pro / VagTacho Alternative

So I've been a happy VCDS user since buying my Golf in 2003 (it had 65000 miles on it so it conveniently needed an immediate timing belt replacement, hence needing VCDS - though it was named VAG-COM way back then). However there are things that VCDS doesn't do, such as pulling the SKC from an...

forums.tdiclub.com

Didn't see a resolution to increasing the number of fobs from 1 (to say 3) and whether that worked.

Also, you put a key in the ignition and turn the car on. If you're doing more than one key do you turn the key off and move between keys (such as adapting them for the immobilizer) between pressing the unlock button on each fob or does the car just have to be on while running this command?

Thus you press unlock for 1 second on key one, the horn beeps, you move to next key, press unlock for 1 second, horn beeps, move to last key, unlock, horn beeps all while key one is left in the ignition with it on.

I'd trying to avoid clearing the CCM to test this if someone's got some insight first since I already have two remotes that work and ultimately just want to add a 3rd. If it doesn't work I think I could be left with just one or perhaps no door remotes.

Bump,

Hey I am looking for some guidance to my next steps. I think I have pulled the correct data to get started. I am looking to reset my 1M KM odometer back to zero or optimally back to 21K miles so I can just say add 600k to that. Help please!

You have a Marelli cluster. There are 2 commands you can try:

kw1281test.exe COM4 9600 17 DumpMarelliMem 3072 1024
kw1281test.exe COM4 9600 17 DumpMarelliMem 14336 2048

If neither of those work then kw1281test may not be compatible with your cluster (and there's not a whole lot I can do to add support unless I have that exact cluster to test with - and even then I may not be able to get it to work).

Unfortunate it didn't work. I was able to get the SKC and disable the Immobilizer from the ECU by using a CH341A. But I currently have a flashing Icon on the dash. Turns out the car I bought has a swapped dashpod so Im trying to gain access to it so i can change the VIN and make new keys. So far I tried all programs to gain access to the Dashpod so far with no luck. VAG Commander gives me different SKC numbers that dont work. VAG EEPROM doesnt work either I get an error code saying unkown software version. Only other option I haven't tried is VAG TACHO but i need a Windows XP to make the software work properly.

How where you able to delete the immobilizer ?

 

[Nate_Grauvogel]

First of all, thank you to gmenounos for the work and the alternative to VDS-PRO!

I bought the cheap CH340 KKL cable in the original post a while back, installed drivers (opened the housing to ensure it's a CH340), and am trying to use a Win10 laptop get my SKC ('02 1C Beetle GLS Turbo) to program a backup key and - if things are stable, enable the remote window rollup/down that I did years ago to my last '02 Beetle (that one was a TDI).

My cluster is a 1C0 920 921 F - verfied with VCDS, and was able to read it only once with KW1281Test and the cheap CH3240 KKL cable.

I think the problems I'm seeing are related to the KKL interface - it worked once to read the software version, but not reliably. I've reinstalled drivers, tried with UART buffer on/off, and tried various baud rates. 10400 never works - can't even wake up the interface. I can't set the COM port to 10400, so using 9600 works with the interface, but results in errors talking to the car's modules. (I've tried reading info from the ECU as well as instruments.)

Here's a typical log just trying to read the software version of the module - any suggestions?

Not sure what to try next other than a different cable or computer. I have a trusty RS-232 serial KKL but no machine to run it with any more, and my VCDS cable is a HEX-NET...too new.

Thank you so much for the hard work of figuring this out. I was able to retrieve my SKC with it on my 2004 PD Jetta. The problem I had was command prompt couldn't find the kw1281test file on my desktop via typing in the name. I was able to click and drag and drop the file into command prompt to run it. Then I typed the last phrase to "GetSKC" and then there it was.

Adapters. I have serial-USB-A and then USB-A to USB-C adapters and that does the trick with my old cable.

Hello all, could someone clarify, is kw1281test only for TDIs? If it works for other cars, what models, years or even makes are generally working?

I have a 12 Jetta, 12 Passat and an 09 Audi A4 I'm trying to make backup key fobs for. The Audi showed the security PIN in VCDS with a rosstech cable upon mouseover of the input field, but the other two did not. Unfortunately I wasn't able to get a response using kw1281test on the other two. I tried a kkl cable also. I tried didn't baud speeds and a bunch of other attempts to get something to work with no success. A locksmith said it won't work on ~2004+ models, but I want to know if that is bs or not.

Thanks a lot. I was hoping this cli tool would be the poor-mans answer to regain the ability to control the vehicles I own. My local dealerships won't give me the pin codes.

kw1281test works on VAG cars which use K-Line for diagnostics. It does not work on your CAN bus vehicles. More details in the FAQ (first post in this thread)

Thank you. That explains a lot!
"With very few exceptions*, all 2008 and newer VW/Audi Group cars require CAN"

So there are no similar software tools for any 2008+ VWs/Audis? What a shame..

So is it the CAN communication protocol that is the barrier or is there something else like obfuscated code that is the problem. Or maybe no one has reverse engineered the protocol for open source like gmenounos? (Big kudos to him btw!)

There are commercial tools like VAGTacho, VAG K+CAN Commander, VAGDashCAN, but they're either expensive or cracked versions from China.

So is it the CAN communication protocol that is the barrier or is there something else like obfuscated code that is the problem. Or maybe no one has reverse engineered the protocol for open source like gmenounos? (Big kudos to him btw!)

For me, the barrier is that I only have K-Line cars to develop and test on. I also don't know if there are any generic CAN cables like there are generic KKL cables.

Hello,
Firstly, thanks so much for developing this tool!

I searched the thread for my cluster but didn't get any results. Is it supported?

Yeah, you may be out of luck with that cluster. I've gotten kw1281test to work with several Audi clusters, but I guess yours is different in some way.

 

[gmenounos]

New release: v0.99.3-beta

• Updated to .NET 9.
• Added support for 8L0920900B clusters.
• Added support for 1JD920826E (software VCB07LL) clusters.
• Added support for 1M0920800C (software S599CAA) clusters.
• Added support for 3U0920842B (software KB5M07HH) clusters.
• After reading the EDC15 EEPROM, logs the SKC, odometer value, VIN and Immobilizer info.
• Fixed wakeup timing issue caused by writing to the log during timing sensitive code.

Ok all good.

In the end I spun up an XP virtual machine and was able get my SKC with VAG K+CAN Commander.

 

[Feche]

case "VWK503LL 09.00":
case "VWK503MH 09.00": // 1J0920927 V02
return [[0x3E, 0x35, 0x3D, 0x3A]];

this will add support for VWK503LL 09.00 clusters, already tested it and it works!
