VCDS allows you to change coding and perform adaptations (like changing battery size or enabling features). If the loader is unstable or poorly coded, it might cause the software to crash mid-way through writing data to a module. This can corrupt the module, effectively "bricking" it and leaving you with a car that won't start and a repair bill in the thousands.
: Using a loader with the wrong firmware or hardware version (e.g., cables not using the ATmega162 chip ) can permanently "brick" the diagnostic cable. No Support : Official updates from Vcds 22.3 Loader Download
