Locating your ECU Box with VCDS
Every Engine Control Unit (ECU) has what's known as a Box Code and Revision. This number indicates which factory version of software is on your ECU. With this information, we can check compatibility of available features and files for your exact ECU. To find this information, you can use a VAG-Com/VCDS OBD-II cable. Start by plugging in the cable, then turn the key to the on position and launch the program.
Alternatively, you can view a saved fault code readout to find your Box Code and Software Revision.
