Standard Xentry diagnostics allow for reading codes, live data, and performing basic adaptations. However, is a special engineering mode designed for factory testing, research, and advanced coding. Key features unlocked by the patched keymaker include:
lifts these restrictions, providing an "unfiltered view on the module’s error memory, therefore allowing to see all stored trouble codes, including the masked ones". When activated, the software displays a German warning screen (except on certain models) indicating that the user has entered a high-risk environment. xentry keymaker v2 1 developer mode patched
