It works with most but there are a few that do not. I should make a list.
If I manage to obtain the SKC through other means...will I be able to use kw1281test to adapt new keys? Following the directions laid out in post #1264? Even if kw1281test won't pull my SKC?

Yeah, it should be able to do that. But since you have an Audi, the adaptation channel might be different. You'll have to research. Whatever channel you'd use in VCDS would be the same that you'd use in kw1281test.

I attempted adaptation save after getting my skc....it did not work...now my immobilizer light is blinking ... and all three keys start the car....fault code when scanned shows
01179 - 35-00
Will the command Findlogins check if the SKC I pulled is incorrect/correct? ((Vcds allowed me to login with the SKC I had but I'm only using the shareware version and so I couldn't use it to adapt the new keys) it showed channel 21 so that's what I used)
Will AdaptationRead or AdaptationTest display how many keys are paired? How are these commands used and to what end?
The car is drivable right now... I'm assuming some how I shut off the immobilizer.

Sorry, but I don't know anything about Audis.

I think you'd be better off asking about adapting keys in an Audi forum. I don't know much about them and how they differ from MKIV VWs.

Hello and thank you for providing what looks like the SKC solution I'm looking for.
My 03 beetle came (recent purchase) with a replaced inst. cluster (also received what I was told is the original cluster) and neither one has gauge functions ( the odometer works on both) when installed. I found this Ross Tech video on swapping clusters and hope to use my VCDS to get the replaced cluster to work. - ECM & cluster swapping
Will kw1281test program help me find the SKC with the replaced cluster?
I see that beetle clusters were made by Magneti Marelli, does that affect using this program?
One last ?, the link for the cable in the first post of this thread goes to a cable that's not available on Amazon, will this one work? - Amazon KKL cable

Yes, it should allow you to pull the SKC from either cluster, but you'll still need to figure out what's wrong with your gauges. kw1281test has generally worked with Marelli Beetle clusters though there are a few Marelli Audi clusters that aren't supported.

I think that Amazon FT232RL-based cable should work fine and will be supported on more computers than the CH341A cables.

Thank you gmenounos for your reply.
My understanding was that the gauges don't work because the cluster is not matched to the car/ECU ?
The ECU has had the immobilizer "deleted", this is what is allowing the car to run and the key to work, would this be correct?

As far as I know, matching the cluster to the car is not necessary for the gauges to work. And, yes, if the ECU has the immobilizer deleted then the car will start even if the cluster isn't matched to the ECU (but the cluster will display an immobilizer warning light).

Thanks again for your help.
Do you have any idea what or where i would look for as reasons why the gauges don't work?

Hello, can anyone help me get out PIN CODE out of my dump for my a4b5 cluster? Didn't had any luck, was trying to convert last 2 bits before immo-id, but I might have done something incorrect, so I still can't access my pin code, could anyone help me out and explain a little bit more or get me the code? Haven't been familiar with HEX codes at all. Here is the download link for my dumps.
From what I understood, the pin for me was 01138, but it didn't work.

Here is also an image from the place, where I should get my pin code as I understood after reading the forum, but didn't get much success..

I don't know much about Audi clusters. Try asking at http://www.nefariousmotorsports.com/forum/ or https://www.digital-kaos.co.uk/forums/index.php

As I understand from what I have read, It should be similar with beelte marelli clusters, so from the dump that I have gotten out of the cluster, can you take a look? maybe there is possibility to convert this pincode out of it?
Try 02124

Did kw1281test make that dump? If so, please post your kw1281test.log file so that I can add support for that cluster.

Thank you! Yes, kw1281test made that dump!
I will try it as soon as I will start to work at garage today, can you please explain how did you calculate it?

and here is the log file. download

Sadly the code didn't work out either, any suggestions what more I could do?

Had a go using my KKL cable and COM4 today.

After getting the correct driver and working out I needed to alter the port in the request to COM4 I did get somewhere.

My aim is to retrieve the SKC code from my Beetle instrument cluster (no issues) and swap it for a custom Polo GTI unit.
I tried the GetSKC request - .\kw1281test.exe COM4 10400 17 GetSKC

Unfortunately with no result. Log shown below. Any ideas? TIA

Thanks for the reply.

I changed the baud rate and got something back but I guess as the message suggests my cluster is unsupported?

Is there any other way than buying VAGTacho at ridiculous expens? I only intend to use it once.

For unsupported Beetle clusters, you can try the following 2 commands:

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

Please report back if either of them is able to dump the cluster EEPROM and then I can add official support for your cluster.

It's not even getting past the initial connection to your cluster where it displays the cluster part number. What kind of cable are you using? Any chance you could try this on a different laptop or with a different cable?

Attempt to use the SKC in VCDS:


YOU SHALL NOT PASS:
My Magic-8-Ball tells me that you're trying to login to address 25 with VCDS-Lite because the cluster is returning the helpful (if you speak German, which I don't, but I know how to use Google Translate) message "Bitte Adresse 17 eingeben", which means "Please use address 17".

My bad, I thought these args pulled SKC from address 17:

It did pull the SKC from address 17 but then you connected to address 25 with VCDS-Lite. Click on the "17-Instruments" button, not the "25-Immobilizer" button. 25 is mostly for cars with a dedicated immobilizer box independent from the instrument cluster. All the MKIV cars in the US that I know of have the immobilizer integrated into the cluster so you use address 17 for general cluster stuff and immobilizer stuff.
