kw1281test: A Free VDS-Pro / VagTacho Alternative

[gmenounos]

New release: https://github.com/gmenounos/kw1281test/releases/tag/v0.81-beta

• Added support for Beetle 1C0920941LX M73 V03 cluster.
• Increased read/write timeout to 8 seconds as some controllers take longer than 2 seconds to respond.

I have an old cable that I think was home made. It's a serial cable and it works with Vag-Com on a windows 11 desktop pc with a serial port. I am hoping your program will work with it and guess no drivers required. Have a 2001 Beetle 1.8T automatic build date Dec. 2000. Not sure if Cluster is supported 1C0920806G.

Try this (replace "COM1" with the serial port that your cable is connected to):

.\KW1281Test COM1 9600 17 DumpMarelliMem 3072 1024

 

[Dynobeetle]

Thank you so very much for reply. Just picked up a HP Probook 650 G2, 6th gen i5 running Win 11 pro. One of a very few modern laptops I could find with a serial port. Will give it a try on that, see if Vag Com still works and then try your program. Really an amazed by the ingenuity of the DIY community out there! I'm 76 and grew up in the Muscle Car era, when tuning was point gap and dist. advance.

I just need my SKC so I can program another key. How do I get SKC from the dump, or is there another command. Have read through a few times and an still a bit confused at this point. Thanks.

Did it work and create a dump? Can you attach kw1281test.log? If you can attach the dump, I can probably tell you your SKC, or by looking at the log I can probably tell you how to determine it with a hex editor.

 

[Dynobeetle]

I think it worked. l got this back. marelli_mem_$0C00.bin. How do I send?

Glad you got it working and were able to retrieve your SKC from the dump. The next version will support your cluster so that you'd just be able to use the GetSKC command to retrieve it.

What kind of cable are you using? Can you attach kw1281test.log ? It contains a log of useful info that helps me figure out why it's not working.

Throttle Body Alignment? You might be able to use it for that. I only have TDIs so I can't test it myself.

First try to connect to your ECU and make sure that your cable is working and that kw1281test can communicate with your ECU. So if your cable is on COM1, then this is what you'd do:

.\kw1281test.exe COM1 9600 1 ReadIdent

Assuming that works, I think this is what would do a TBA:

.\kw1281test.exe COM1 9600 1 BasicSetting 60

It should run for about 30 seconds and then you can quit.

Hey man, I just wanted to let you know that your instructions worked for me. I just had to change the baudrate to 10400. In any case, believe it or not, I’ve been looking to do a TBA on my car for the past 9 years, and I had periodically done countless hours of research to find a free or cheap solution. Finally, I’ve been able to find that with your help and I couldn’t express enough how much I appreciate the time and effort you’ve put into this. It means a lot to me and you’ve made my day. Thank you.

Has anyone got this to work with Audi B7 Instrument Clusters?

I've tried a couple of cables I already owned and number of drivers but the "best" response I got was

Caught: System.InvalidOperationException Controller did not wake up

Every other variation of what I tried returned Could not find COM#


So is this fantastic project not compatible with B7 Clusters or do I need to get the specific cable listed? (I've just ordered it but am curious if this was a waste of time)

Love the effort keeping it open source. Thanks, T

04 Audi TT 225 BEA here. I got my bin using the second command referenced on page 20.
kw1281test.exe COM3 9600 17 DumpMarelliMem 14336 2048
It successfully saved the Bin. I then used the following command to convert to txt
certutil -encodehex marelli_mem_$3800.bin marelli_mem_$3800.txt

However now I do not know which line to read for the SKC. People say that is the 2 bytes before AUZ5 well there are 3 and the bytes before all of them to me look different. The formatting is a little messed up but this is what i got.

I think you're probably out of luck. The best way that I know of to determine if kw1281test supports your car is to look at this page: https://www.ross-tech.com/vcds/canbus.php
If your car is one of the ones listed, then kw1281test does not support it. The cables that kw1281test supports are all generic K-line cables, so not only can't those cables connect to the CAN bus in a car, I don't own any cars that use CAN bus for diagnostics, so I wouldn't be able to do any testing. In the case of the B7 cluster, there's a small chance it might work because the above page says "some control modules" use CAN bus for diagnostics. So when your cable arrives, you can try connecting to the cluster with the ReadIdent command and see if it works. Of course connecting to a module is one thing, but being able to retrieve the SKC is a lot more complicated and varies from cluster to cluster, so you still may be out of luck.

It's consistently 0809 in that dump. 0809 in hexadecimal is 2057 in decimal so you can try 02057 for your SKC. However I was trying to help another person recently who sent me a TT dump and the SKC, calculated in the same way didn't work, so please let me know if it works for you.

 

[Ascenity]

I ran the dump through AudiDashEdit & it shows "02057" so I'll second that, that should be correct - each Audi TT MK1 SKC dump I have pulled with kw1281test has always given me the correct SKC.

----

Edit: I lost my MK4's radio code (Blaupunkt - Gamma 4) and my TT never came a code (Blaupunkt - Concert) - are you aware of any development aimed towards these radios that could be implemented into kw1281test? Unfortunately, mnaberez's vwradio doesn't support those units & looks like you need to pull the eeprom and dump it, just to get the code (or pay a "radio code" company).

Edit#2: Seems I've answered my own question: looks like mnaberez was looking into European radios, but can't find much else online.

 

[AustinZimmy]

That worked! Thanks guys, I was over here scratching my head. Did a few tests and was able to get into Instruments, Engine, and Central Lock Controllers via VCDS with that pin.

It seems that the Cluster has a response and not the ECU. So it's clearly doing something

Do you think there is any thing that could be done because it's actually waking up the module?

It seems 10400 gets a better return than 9600 as there were couple additional lines

I couldn't get it to DumpEeprom or any other command I tried


I'm fairly sure they're all Bosch Clusters in the B7, including a set I have in front of me from a S4. But there is a mix of ECU's (certainly in the TDI's) of Bosch and Siemens if I'm not mistaken.

I have a number of A4 B7's both TDI and TFSI from 2005 through to 2008. I can test any number of them. I also would love to help in any way I can and contribute to the project. I don't know #C, I mainly learnt PHP back in the day so can very much appreciate the work and making it open source is really commendable

Any further help or even if you need a cluster, I'd be very happy to help
Tim

Ok apologies I took my time, I wanted to make sure I did a full ECU read (save) if somehow running into an issue. I know the ECU isn't the Cluster but I have the ability to read it so it made me feel better in case something did get bricked

Yes, these aren't TDI's but I didn't want to chance bricking my daily driver which is TDI

Is there anything else you want me to try?

I can send you my ECU read file if that would be of any use

When you have a chance, could you try a few more times and verify that this command always returns "Controller did not wake up"
.\kw1281test COM6 10400 17 DumpRBxMem 66560 1024

and this one wakes up the controller and says "Protocol is KW 2027 (8N1)"?
.\kw1281test COM6 10400 17 ReadIdent

Thanks.

Nps,

I've tried it now a number of times and in a number of different cars. TDI and TFSI it doesn't matter the same responses

I tried it with ignition on, ignition off, tried it immediately after clocked light up and also giving it a minute to have fully 'woken up'.

The same responses each time below.

Does it waking up at all with ReadIdent give you any indication of what to try next?

Hey guys I own a Golf MK4 3-door from '01 with the CCM '1J0 959 799 AH'. I'm trying to get the windows to open/close with the fob and I've been having some trouble working with the kw1281test. I've managed to find which adresses and values I need to change and when I try to read the eeprom in those values most of the times it doesn't work. First time it worked like it was suppose to:

Version 0.80-beta (https://github.com/gmenounos/kw1281test/releases)

Received "Read EEPROM Response" block: 48

Right after, I try the same command and it doesn't work anymore, just returns this instead:

EDIT: I've found out that unplugging the usb cable and plugging it back in between commands would make it work.
I've already changed all of the values for :

1J0 959 799 AH 046 Sedan
Address Old New Remark
04295 138 64 This memory address added to keep the rear trunk handle from locking the car
04283 138 64
04289 138 2
08628 242 246 driver side front window
12724 250 254 passenger side front window

and the windows still don't open/close with a long press

Nps,
I've tried it now a number of times and in a number of different cars. TDI and TFSI it doesn't matter the same responses

I tried it with ignition on, ignition off, tried it immediately after clocked light up and also giving it a minute to have fully 'woken up'.

The same responses each time below.

Thanks for doing all that testing. I've published a new release: https://github.com/gmenounos/kw1281test/releases/tag/v0.82-beta

Can you download it and try this new command:

.\kw1281test COM6 10400 17 DumpRBxMemOdd 66560 1024
