• Proper cooperation with diesel – turbocharger designed to work with the high torque typical of diesel engines.
• Reduced risk of controller errors – no need to modify ECU software while maintaining the original specifications.

Condition, installation and service recommendations

The turbocharger offered is in used condition, which means that a standard workshop inspection is recommended prior to installation: checking rotor clearances, vacuum system tightness, and the condition of the geometry control actuator (if present in the configuration). Proper preparation for installation directly impacts the durability and smooth operation of the entire turbocharging system.

During installation, it is worth paying attention to:

• thorough cleaning of oil and intake lines,
• engine oil and filter change,
• checking the tightness of connections when cold and after the unit has warmed up,
