XENTRY
XENTRY is Mercedes-Benz's official diagnostic software platform, used at authorised dealers and at independent specialists with the right tooling to read every module on a modern Mercedes.
What it means
XENTRY is the successor to Mercedes's earlier STAR Diagnosis platform. It connects to a Mercedes through the OBD-II port (with a brand-specific multiplexer) and reads every electronic module on the car: engine, transmission, ABS, airbag, body-control, infotainment, climate, lighting, and dozens more. Generic OBD-II readers can only see basic powertrain codes; XENTRY reads everything, runs guided diagnostics, performs adaptations and resets, and codes new modules to the car. Mercedes-specific procedures (resetting the service interval, registering a new battery, calibrating sensors, programming a replacement key) all require XENTRY or a XENTRY-equivalent tool. Without it, an independent workshop can swap parts but cannot do most of the post-replacement coding the car expects, which leaves warning lights on and adaptations stuck at default values.
Why it matters in Singapore
Singapore Mercedes owners increasingly want to use independent specialists rather than authorised dealers, both for cost and for relationship. The deal-breaker for most independents is the lack of XENTRY-equivalent diagnostics, which limits what they can actually do. A workshop with proper Mercedes diagnostic capability can deliver dealer-equivalent quality at independent prices, which is the model Revol Carz Garage runs on.
How Revol Carz handles this
Revol Carz Garage uses Mercedes original handset diagnostics (XENTRY-equivalent) for every Mercedes job. Diagnostic results are itemised, explained in plain English, and used to scope the repair before parts are ordered.
