Frequently Asked Questions

Is the M139 engine’s known oil consumption issue addressed in this manual?

Yes. The manual includes full diagnostic routines and repair procedures for the M139 2.0L turbo, including piston ring inspection intervals, valve stem seal replacement steps, and Mercedes-Benz’s official oil consumption measurement test — a documented concern on early GLA 45 production units.

Does this software cover both the GLA 45 and GLA 45 S variants?

Coverage applies to the full AMG GLA 45 4Matic+ range on the H247 chassis, including the higher-output GLA 45 S 4Matic+ (421 hp tune). Both share the M139 engine and Speedshift DCT; the software distinguishes specifications by sales model and engine mapping where applicable.

Are AMG-specific electronics and MBUX diagnostics included?

Yes. The software provides complete wiring schematics, connector pinouts, and ground-point locations for AMG performance electronics, the MBUX infotainment suite, driver assistance modules, and body control units — enabling thorough electrical fault diagnosis beyond what generic scan tools offer.

What format is the manual?

This is dealer workshop software, not a PDF. It runs on Windows XP through 11, Mac, and Linux, and features menu-driven navigation, search by engine code or gearbox code, zoom-in diagrams, and integrated wiring schematics — identical to the tooling used at Mercedes-Benz authorized service facilities.
