Whats the benefits of in-house diagnostics?

Hella Gutmann launches its latest diagnostic tool, the mega macs S 20, an “advanced multi-brand diagnostics for Android devices”.


Hella Gutmann’s latest diagnostic device, the mega macs S20, brings improved diagnostic capabilities to garages at a cost-effective price. The new tool was launched last year at Automechanika Frankfurt 2024 and builds on the success of its predecessor, the mega macs ONE. Hella Gutmann’s mega macs X stood out for its unique features, including selectable software modules, diagnostics over internet protocol (DoIP), and the ability to assess the state of health (SoH) of electric vehicle batteries. Now, these advanced features are available in a more affordable option with the new mega macs S 20, making it a great choice for workshops looking for a scalable and straightforward diagnostics solution.

Features include…

“We’re giving workshops the flexibility to use their own Android devices for advanced diagnostics, without compromising on performance,” said Julian Goulding, head of sales at Hella Gutmann. “It’s a powerful combination of affordability, efficiency, and cutting-edge technology that sets a new standard for modern vehicle diagnostics.”

Powering the new mega macs S 20 is Hella Gutmann’s smart diagnostic interface (SDI), previously only available on its flagship devices. It ensures maximum clarity and a quick, intuitive diagnostic process with support for DoIP and CAN-FD protocols.

“Technicians simply plug the mega macs S 20 dongle into the vehicle’s OBD port and connect to it via their Android tablet or smartphone using Bluetooth or USB-C,” said Julian. “Two flexible software modules bring a choice of functions for workshops, from basic to advanced capabilities.”

The S2 license includes functions like reading/clearing error codes, service resets, and adjusting settings. It also comes with regular software updates and new vehicle model support.

Advanced functions such as mileage queries, coding, parameter viewing, actuator tests, and access to Hella Gutmann cyber security management are also available with the S2 license. It means the new mega macs S 20 can also unlock cyber security gateways within a fraction of a second. With BMW recently added, CSM now supports cyber security diagnostics for 17 brands.

An S3 license unlocks premium features like error code-based repair suggestions, access to the Hella Gutmann knowledge database, and HV battery diagnostics PRO. This enables the mega macs S 20 to assess EV traction batteries using ‘Battery Quick Check’, a feature once exclusive to the mega macs X. For workshops specialising in advanced battery services, the S-Battery license is the perfect solution.

The top 10 remote diagnostic jobs requested

New data from Hella Gutmann reveals that the most common workshop task performed using its macsRemote Services is the replacement of the steering assistance module. Here is the list in full: 

  1. Steering assistance module replacement 
  2. Front radar module replacement 
  3. Front radar calibration 
  4. Front camera calibration 
  5. Headlight module replacement (single headlight) 
  6. Engine control module flash programming 
  7. Airbag module replacement
  8. Key transponder programming
  9. Remote diagnostic support
  10. Adblue warning reset

Hella Gutmann’s macsRemote Services gives workshops the OE capability to carry out calibrations and coding on vehicles via remote connection. “Where they were previously locked out of jobs because of lack of data or access authorisations,” said Julian, “or because the vehicle is too new for their usual diagnostic tools, garages can now call on Hella Gutmann’s remote experts.

“You simply connect the macsRemote device to the car and create a job ticket through the Hella Gutmann online portal. At this point, our technical experts can access all the vehicle’s electronic systems remotely and perform tasks using vehicle manufacturer diagnostic equipment.”

With no ongoing licence charges, it is a cost-effective pay-as-you-go solution. “As well as meaning garages provide a more complete offering for customers,” said Julian, “workshops can also boost profits. Jobs can be carried out in-house at a competitive price, instead of being passed up or passed along. It’s a win-win.”
