Frequently Asked Questions
Which chassis codes are included – does it cover W204, W212, and W166?
Yes. The WIS 2015 database spans every Mercedes-Benz chassis produced through the 2015 model year, including W204/W205 C-Class, W212/W213 E-Class, W221/W222 S-Class, W166 ML/GLE-Class, X166 GL-Class, R172 SLK, W218 CLS, and commercial platforms such as the Sprinter NCV3. You can search by chassis code, sales model number, or engine/gearbox code directly within the software.
Does the Freightliner Sprinter (US-market) share coverage with the Mercedes Sprinter?
Yes. The US-market Freightliner Sprinter is mechanically identical to the Mercedes-Benz Sprinter NCV3. WIS repair procedures, wiring diagrams, and parts data for the Sprinter apply directly to the Freightliner-badged variant sold in North America through 2015.
Are interactive wiring diagrams included for CAN-bus and SAM module diagnosis?
Absolutely. The bundled EWD module provides fully interactive wiring diagrams covering engine management, the high-speed and low-speed CAN networks, front and rear SAM modules, COMAND infotainment, KEYLESS-GO, ESP/ABS, climate control, and all lighting circuits. Diagrams include wire colors, connector pinouts, component location views, and ground point maps – identical to what dealer technicians reference when diagnosing electrical faults.
What format is the manual?
This product is professional OEM dealer software, not a PDF. It is delivered as a Virtual Machine that runs on Windows 11, 10, 8, 7, Vista, XP, Mac, and Linux. The interactive environment provides the same searchable WIS repair data, ASRA labor times, EPC parts catalogue, and EWD wiring diagrams used by authorized Mercedes-Benz dealerships in the United States and worldwide.
