Frequently Asked Questions

Is the AIRMATIC suspension system fully covered?

Yes. The software includes complete AIRMATIC diagnostic and repair procedures for the X166 GL450, including compressor testing, air strut replacement torque specs, ride-height sensor recalibration, and fault code definitions specific to the 2013-2015 model years.

Does this cover all X166 GL-Class variants or just the GL450?

This product is specifically scoped to the GL450 4Matic on the X166 platform for 2013-2015. The X166 family also included the GL350, GL550, and GL63 AMG, but powertrain and calibration data in this software is tailored to the M278-equipped GL450 with 4Matic AWD.

Are interactive wiring diagrams included for the COMAND infotainment system?

Yes. The software provides color-coded, searchable wiring diagrams covering engine management, 4Matic transfer case control, AIRMATIC, COMAND NTG 4.5 infotainment, climate control, lighting, and all body electronics – with component locators identifying connector positions and ground points.

The interactive platform includes searchable repair procedures, diagnostic trouble code look-up, hyperlinked wiring diagrams, and step-by-step service instructions identical to what authorized dealerships use. Compatible with Windows, Mac, and Linux operating systems.
