Marelli Motori offers technical support and ultra-fast response no matter where in the world you are located.

For a plant to operate efficiently, disruption must be kept to a minimum and, when problems occur, corrective actions must be implemented quickly and effectively.

Our highly trained service engineers are trained to react quickly to any situation anywhere in the world. We rapidly analyse the source of machine problems and prescribe situations which can get you 'up and running' quickly, minimising downtime and production losses.
