Disabling Prestart on a DAF using software — Prestart Disable
We offer a pre-start system deactivation service on DAF trucks , which allows you to remove restrictions and delays before starting the engine.
The Prestart system is responsible for preliminary checks and starting conditions, but if there are malfunctions or under certain conditions, it may interfere with the normal operation of the vehicle.
👉 All work is carried out separately and individually , for a specific car and task.
