About us
We have been present on the market for over 20 years. From the very beginning, we have operated in the diesel engine industry, with a particular focus on fuel systems. Along with technological advancements and the introduction of new solutions by engine manufacturers, we continuously expand our range of services to include the latest systems. Recently, we have also extended the scope of our activities to include electric vehicles.

Advanced Computer Diagnostics
During road tests, we record dynamic data logs which are then analyzed on a computer. This approach allows for highly targeted diagnostics, reducing repair time and helping to lower overall repair costs.

High-Voltage Injector Coil Testing
We test injector coils under high voltage to eliminate cases where an injector passes bench testing but fails to operate correctly once installed in the engine.

Onboard Charger Repair
We repair onboard chargers for electric vehicles, including root-cause analysis of failures and PCB reconstruction. This allows the system to be restored to full functionality without replacing the entire module.
