If you're looking for a reliable STAR diagnostic scanner, there are a few options that come highly recommended by automotive professionals. One popular choice is the Xentry Diagnostic tool, which is specifically designed for Mercedes-Benz vehicles and offers comprehensive functionality, including the ability to deactivate SBC for brake jobs and run rodeo mode for ABC flushes on your R230. Another option is the Autel MaxiSys series, which provides extensive vehicle coverage and advanced diagnostic capabilities. Both tools can significantly enhance your diagnostic experience beyond basic OBD2 functions.
