Introduction.

Hello,

I am releasing another patch, this time is for cluster VWK501LL versions 1.00 and 0.83.

This is the first public patch (AFAIK) for a Low Line cluster, so if you enjoy this mod – please consider a small donation/tip! 🙂

Led sweep is not yet working – will be released in the future.

The patch.

Installation.

ATTENTION: always make a backup prior to modification!

You will need your cluster EEPROM dump, you can use kw1281test in order to do so – once you have your dump, open it in any hex editor and go to address 0x4F4, paste and save the file.

Upload.

In order to upload the patch code, I highly recommend using kw1281test, patch can be uploaded over the K-Line using a OBDII ‘dumb’ KKL interface using this software – it will not be covered in this blog post, that is for another time.

Disclaimer.

ATTENTION: the code is ‘as-is‘, it has been heavily tested but use it at your own risk, I am not responsible for any damage and/or malfunction to the cluster.

If you enjoy the mod, please consider donating since this is very time consuming, reverse-engenieering the code is something hard to do.

I also want to thank gmenounos for the software kw1281test, without it this patch would have been very hard or near impossible to make.

Also thanks to Michal Kolus for the video.

Happy modding 🙂
