Q: Can't I just buy a cheap VagTacho cable from eBay?Ī: Most (all?) of the copies of VagTacho and similar tools on eBay are cracked copies of much more expensive commercial products.

You'll also need it if you ever need to install a replacement cluster or ECU. You can also use older VCDS cables if they support VCP mode.Ī: You'll need it if you want to match a new key to your car. Drivers for that cable can be found here. It will not work on cars that use CAN bus diagnostics such as those listed here.Ī: You need a KKL cable like this one. It's been most heavily tested on the VW MKIV Golf/Jetta/Beetle. For VWs, this means only MKIV cars are supported.Ī: The latest version should always be here: (look under Assets) A list of commands is here: Ī: kw1281test works with many VW group cars that use the K-Line for diagnostics. But it's a command line program and only works with cars that support diagnostics via the K-Line. It's open source so you can copy it, modify it or just read through the source code to understand how it works. It runs on Windows 10/11, macOS and Linux.

While reading through the 1000+ posts might be interesting, it's not going to get you your SKC or mod your CCM very quickly. When I started this thread, I didn't realize that it would grow so large.
