Diagnostics at its best: Hella Gutmann unveils mega macs PRO at Automechanika 2026

• The direct successor to the mega macs X combines intelligent software, AI-powered diagnostic support, and state-of-the-art hardware in a premium diagnostic platform
• macsNova as the integrated intelligence of the Hella Gutmann ecosystem: structured workflow, proprietary diagnostic expertise from over 30 years, and the technician as the decision-maker

Ihringen, 8 September 2026. Hella Gutmann Solutions, a leading provider in the field of vehicle diagnostics and workshop equipment, presents the new generation of professional vehicle diagnostics with the mega macs PRO. As the direct successor to the mega macs X—one of the most established and best-selling diagnostic systems in the Hella Gutmann portfolio—the system combines powerful hardware, intelligent software, comprehensive vehicle data, and a future-oriented ecosystem into a single premium diagnostic platform.

At its core is the integration of macsNova—Hella Gutmann’s diagnostic intelligence, which is available across platforms on the mega macs PRO, mega macs S20, and mega macs PLUS—and combines diagnostic expertise, vehicle data, intelligent assistance, and workshop processes into a seamless diagnostic and repair workflow.

“With the mega macs PRO, we’re setting a new standard for professional vehicle diagnostics. macsNova brings more than three decades of Hella Gutmann diagnostic expertise directly into the workshop’s workflow: structured, prioritized, and always with the technician as the decision-maker. This enables workshops to move more quickly from the error message to the correct diagnostic decision—without having to leave their usual workflow,” says Niklas Wedler, Product Manager for Diagnostic Products at Hella Gutmann Solutions.

New Software Platform: Diagnostics, Repair Information, and Vehicle Data in a Single Application

The newly developed software combines diagnostics, repair information, and vehicle data in a single application. A redesigned fault code view helps technicians grasp relevant information more quickly and evaluate fault patterns more efficiently—with fewer clicks to access the full fault code text.

Complex vehicle data is clearly visualized through a modern parameter display and translated into clear recommendations for action. Repair information, technical data, and guided measurements for low- and high-voltage applications, as well as low-pressure tests, can be integrated directly into the diagnostic workflow.

Through the integration of macsData PRO, technical data and repair information are available directly within the diagnostic tool. This brings diagnostics, information, and workshop processes together in a single working environment.

macsNova: Three Decades of Practical Knowledge—Harnessed by AI

What sets macsNova apart from generic AI solutions is Hella Gutmann’s closed and controlled knowledge base. Unlike systems that rely on generally available content, macsNova is based exclusively on Hella Gutmann’s proprietary diagnostic knowledge, vehicle data, and workshop expertise. The foundation consists of more than 100 million vehicle histories, 100 billion parameter measurements, and 2 billion fault code data records, as well as insights from millions of real-world diagnostic and repair procedures—supplemented by experience from the technical hotline and the expertise of diagnostic specialists and data engineers.

The macsNova features kick in when a diagnostic case becomes confusing or particularly complex: Automatic Diagnosis assists with vehicle analysis and provides prioritized causes of faults based on billions of documented diagnostic data points. The Diagnostic Assistant guides technicians through challenging fault cases and leads them in a structured manner through the next logical test steps. With the AI Help Call (Smart Help Call), relevant vehicle and diagnostic data can be transmitted directly from the diagnostic interface to the Hella Gutmann hotline as needed—eliminating the need to repeat problem descriptions, as support builds directly on the data already available. The technician retains control at all times: macsNova structures, prioritizes, and recommends—but the decision is made by the technician in the workshop. Access to Protected Vehicle Systems: Cyber Security Management

More and more manufacturers are securing their vehicles with security gateway modules that prevent unrestricted diagnostic communication without special authorization. The integrated Cyber Security Management (CSM) of the mega macs PRO solves this problem: Workshops authenticate themselves once, free of charge, with Hella Gutmann; the system then automatically unlocks vehicle gateways—without the need for separate registration on OEM portals. Currently, 19 brands are supported, including Audi, BMW, Mercedes-Benz, Renault, and Volkswagen. Hardware Concept: Compact, Modular, and Powerful

At the heart of the system is a compact Vehicle Communication Interface (VCI) combined with a high-performance display unit—available with either a 10.1-inch or 13.1-inch screen. Four progressive license tiers allow for a configuration that precisely matches the diagnostic needs and workflow of each workshop.

With mega macs PRO, Hella Gutmann combines diagnostics, data, processes, and intelligent support into a single platform. As part of the Hella Gutmann ecosystem, macsNova is continuously expanded with additional validated features—an open platform that grows with the requirements of modern and future vehicle generations.
