Mega Macs 77

The fastest ever diagnostics from Hella Gutmann.

With its real-time repair concept, Hella Gutmann has taken a quantum leap into guided repair support. For the first time, the professionals in the workshop have been able to benefit from fault code-based and symptom-based repair aids that include images and written instructions. All fault codes including parameters can be transferred directly from the Car History to the experts in the Hella Gutmann Technical Call Centre at the touch of a button. From there, the workshop is given personal assistance until even the most complicated repair case is successfully resolved.

Now we’ve turbocharged our real-time repair concept and taken the new mega macs 77 up a few gears. For the workshop, this means the fastest and most complete diagnostic and repair support ever provided by Hella Gutmann Solutions.
