I am neding to change my speedometer from looking at the VSS value to looking at the ABS value. Would this be correct: c:\users\micha\Desktop\tdi\kw1281test\086_beta com2 10400 17 ReadEeprom 0x065 to read what this value is? If so, then do I use the WriteEeprom function then the new specified value to update it?

Trying to understand how to use command prompt with this KW1281test tool.

Should mention this would be used on my 2003 Jetta

Yes, that's right. Just make sure that your cluster is running the VWK501 software (see line below that starts with "00: VWK501"). If it's not VWK501 then 0x65 probably won't be the right EEPROM address to change the speedometer sensor.

Sending EndCommunication block

Assuming VWK501, if the low order bit of address 0x65 is 1 then it uses the ABS sensor. If the low bit is 0 then it uses the VSS. So if the cluster returns 0x80 then it's using the VSS and you'd change it to 0x81 to use the ABS:

.\kw1281test.exe com2 10400 17 WriteEeprom 0x65 0x81

But before you write anything to the cluster EEPROM, you should first dump the whole EEPROM to a file, so if you screw anything up, you can get back to where you started:

.\kw1281test.exe com2 10400 17 DumpEeprom 0 2048

Thank you Greg. I will give this a try soon.
As for the dump, I did that about a month ago. I was a little confused with it as there was nothing in the address that resembled 0x065, or any of the others for like the needle sweep or lit needles, so was not sure if I did it correct. I looked for your email to try to send you the dump file, but did not find it on the github page. I will post it here and see if it makes sense to you.

Hi All
I'm after some advice, injector pump failure on my car. I've replaced it with a new one that now needs coding to car.
I came across this thread and hoping it would help me out. I ran the program as described and it returned the following.

I've tried contacting auto locksmiths but trying to get one to come out to have a look is near on impossible!

The injector pump doesn't need coding.
It looks like the cluster has no communication by what I see there.

Yes, that's right. Just make sure that your cluster is running the VWK501 software (see line below that starts with "00: VWK501"). If it's not VWK501 then 0x65 probably won't be the right EEPROM address to change the speedometer sensor.

.\kw1281test.exe com2 10400 17 ReadEeprom 0x65 ... Protocol is KW 1281 (8N1) ECU: 1J0920946C KOMBI+WEGFAHRSP VDO V20 Software Coding 17232, Workshop Code: 00000 Sending Custom "Read Software Version" blocks Sending Custom "Unlock Additional Commands" block 00: VWK501MH $10 $01 ... Sending ReadEeprom block (Address: $0065, Count: $01) Received "Read EEPROM Response" block: 80 Address 101 ($0065): Value 128 ($80) Sending EndCommunication block

Assuming VWK501, if the low order bit of address 0x65 is 1 then it uses the ABS sensor. If the low bit is 0 then it uses the VSS. So if the cluster returns 0x80 then it's using the VSS and you'd change it to 0x81 to use the ABS:

.\kw1281test.exe com2 10400 17 WriteEeprom 0x65 0x81

But before you write anything to the cluster EEPROM, you should first dump the whole EEPROM to a file, so if you screw anything up, you can get back to where you started:

.\kw1281test.exe com2 10400 17 DumpEeprom 0 2048

This worked perfect. It has been three years since I have had a speedometer so thank you so much. Now time to play around with some other mods.

Thank you Greg. I will give this a try soon.
As for the dump, I did that about a month ago. I was a little confused with it as there was nothing in the address that resembled 0x065, or any of the others for like the needle sweep or lit needles, so was not sure if I did it correct. I looked for your email to try to send you the dump file, but did not find it on the github page. I will post it here and see if it makes sense to you.

So 0x65 is just the address (i.e. location) in the EEPROM that the speed sensor setting (i.e. 0x80 or 0x81) is stored. If you look at the below EEPROM dump, you can see that kw1281test asked for the 16 bytes (aka $10 or 0x10) of EEPROM data starting at location $60. The data that came back was 0xFF for locations 0x60-0x63, 0x08 for location 0x64, 0x80 for location 0x65, and 0xFF for the rest of those 16 locations:

Code:

kw1281test\086_beta com2 10400 17 DumpEeprom 0 2048 2003JettaTDI
...
Sending ReadEeprom block (Address: $0060, Count: $10)
Received "Read EEPROM Response" block: FF FF FF FF 08 80 FF FF FF FF FF FF FF FF FF FF

And for those more familiar with cars than computer programming, $60 and 0x60 are both ways of saying that the number is in base-16 (aka hexadecimal or hex) and not base-10 (aka decimal). kw1281test will let you enter EEPROM/ROM addresses and values in decimal or hexadecimal (if you prefix them with either $ or 0x). I'm pretty inconsistent with which format I use, so that might be confusing. Here's a converter in case you need it: https://www.rapidtables.com/convert/number/hex-to-decimal.html

You can always PM me and I'll send you my email address or you can find it on this page: https://bitfab.com/Contact
(I try not to post it in too many places to reduce the amount of email spam I get)

Lol. I cannot tell you how many times I have had the mechanical portion of my car torn apart. I am a mechanical engineer, but I cannot code for crap. Need to study up and learn it though.

Now that I am more awake, and looking at this on a computer and not my phone, I understand more what is going on. Each row has 16 addresses, starting at 0 and ending at 15. It is slowly making more sense. Thank you for the explanation to a coding dummy.

Still can't get 2 spare keys programmed for my 2008 VW beetle. I went to a local locksmith, and they couldn't get a cloned key to work on my car. After about 3 hours of trying to pull the pin and cloning a key, they handed my keys back and said you need to go to the dealer. I just can't believe no one has found a work around to do such a basic thing of adding a key. I'm so disappointed and frustrated with this whole spare key problem. Anybody ever deal with this issue on 2008 New Beetle?

kw1281test might work with a 2008 Beetle, which supposedly didn't switch to CAN Bus until 2012. Try the latest version and if it doesn't work, please post what kind of cable you're using and attach the kw1281test.log that's created.

Ok, instead of:
kw1281test.exe Com3 9600 17 GetSKC
try:
kw1281test.exe Com3 9600 17 DumpMarelliMem 14336 2048

If that works, it'll create a .bin file that you can email me and I'll hopefully be able to get the SKC from it. I can also add support for that type of cluster in the next version.

This is what I got

gmenounos · Feb 9, 2024

I'd recommend trying that same command a few more times. Timeouts happen sometimes with some clusters but they all usually work eventually.

Mhughes216 · Feb 10, 2024

I'll give it shot and let you know.. thanks

Well I got the cluster to do something on this try

Maybe try a couple more times. If it always gives a timeout error right after "Sending block 0x6C, Writing data to cluster microcontroller, Receiving ACK" then there might be something about 2008 Beetle clusters that isn't compatible with kw1281test.

Yeah it gives me that every time. There is a video on you tube about the chip being different, so I'm going educate myself on. Thanks for your help!

Hi guys,
I need some help from you about KKL Cables that I want to order from AliExpress. Can somebody just confirm what I found on AE, to pick up the right one, here is the link and some info about Cables that I found, need for my VW Golf 4 TDI with IMMO3, thanks.

AliExpress
1) VAG KKL 409.1 OBD2 Scanner CH340 Chip - (6,69€ with shipping)
2) VAG KKL 409.1 FTDI FT232RL Chip with Switch - (9,01€ with shipping)

1. Support OS: Windows XP, Windows 7
2. 409 is for F.i.a.t, for V for A for G
3. Chip CH340 or Chip 409 FTDI FT232RL Chip With Switch
4. 16pin OBD II style Data Link Connector

SWITCH options
Cable used to include a 4 way to switch to different ECU's access:
Position 1 = engine ECU (read / clear engine failure)
Position 2 = airbag ECU (read/remove airbag failure)
Position 3 ECU = ABS (read / erase fault code)
Position 4 = ESP ECU (read / clear fixed fault)

1)

2)

Either will work. If you get the one with the switch, it needs to be in position 1 (labeled "7" in the photo) to work with your Golf.

norrinraddhr · Feb 15, 2024

Hi Greg,
thank you for your help and fast reply. I have seen many KKL Cables on AE, mostly they have three sorts of Chips and I like this Cable with FTDI Chip inside and Switch options, but what I don't know is how is the situation with drivers and Windows 7 that I use on my IBM/Lenovo laptops and what would you prefer?

VAG KKL Cables and Chips
1. Chip CH340
2. Chip CH340T
3. Chip 409 FTDI FT232RL With Switch options

turbodieseldyke · Feb 15, 2024

They're 10 bucks and 7 bucks. Why not get both?

Windows 7 drivers are available for both CH340 and FTDI:

If the FTDI chip is genuine then it's probably better, but there have been problems with fake FTDI chips in cheap Chinese cables: https://www.sevarg.net/2017/03/04/fixing-fake-ftdi-ft232rl-adapters-ssop/
so beware.

Another successful cluster hack for VSS via CAN using kw1281test. I made a video about it... and I didn't remember the right baud rate, so here's an illustration of how important that is. lol

You can almost see what I'm typing. heh. You can select 4k video quality and go full screen, you can just about read it.

Someone did confirm to me that 2000-2001 cars can pick up VSS via CAN if you do swap to a newer cluster. Puts to rest my question on if the older Mk20 modules were infact sending the correct signal for a newer cluster to pick up.

02S swap all the mk4 TDIs! haha
