MD1CS004 bench cable

This activation enables support for the Bosch MD1CS004 bench cable, including all its supported wiring variants (if multiple exist).
To use this activation, you'll need an Express Box along with the C3 Cable (105-91pin connectors) which together provide the physical connection to the ECU.

Each of our cables (C1, C2, ... Cx) can connect to multiple ECUs in both boot and bench mode, depending on the activations.
Thanks to this innovation, full ECU coverage is achieved with just a few physical cables, supporting over 350+ types of control units and their 440+ wiring variants.
This allows you to expand your bench cable coverage with an investment of only 8–39 EUR per ECU, compared to the 80–250 EUR cost of traditional bench cables.

This MD1CS004 ECU is implemented across the following vehicle brands. With the Express Cable, you're fully covered: Audi, Volkswagen

You can buy the (physical) cables with full activation included - this is the most cost-effective option.
If you'd rather start small and expand later, you have two options: activate ECUs one by one (like this MD1CS004), or save more by purchasing a bundle of, say, 10 bench cable activations in advance - and decide later which ECUs you want to activate.

Note: The physical cable, Express Box, and other items shown are not included - they are for demonstration purposes only. This is a software activation for use with an existing Express Cable set.
