Diagnostics

Accurate diagnostics is the difference between a repair that solves the problem and one that only postpones it.

We work with genuine ZF and Voith diagnostic equipment — not third-party tools, not universal diagnostic systems — and with technicians trained to use it according to factory procedures.

ZF Testman

ZF Testman is ZF's factory diagnostic system — the same one ZF uses in its own certified workshops worldwide.

  • Access to all faults and parameters of ZF systems

  • Reading of fault codes and fault history

  • Programming and calibration of components

  • Updates directly from ZF engineers

Voith ALADIN / DIWA Diagnostics

For Voith DIWA and DIWA NXT automatic transmissions we use Voith's original diagnostic tool:

  • Full analysis of the oil and control circuits

  • Diagnostics of individual valves and hydraulic components

  • Recording and analysis of operating parameters

  • Identifying problems before a full teardown

How the diagnostics work

  1. Initial consultation — you describe the symptoms, we ask the right questions

  2. Connection and scan — we read all active and stored fault codes

  3. Analysis — we interpret the data with the experience of people trained directly by the manufacturers

  4. Report — you get a clear explanation of the problem and the recommended actions

  5. Solution — repair in our workshop or guidance on the right next step

We don't guess. We don't swap parts by trial and error. We find the real problem.
