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.

When Prestart Disabling Is Required

People contact us when:

• there are delays when starting the engine
• the car won’t start due to system errors
• there are failures in the preliminary check process
• the equipment operates in difficult conditions (low temperatures, etc.)

What does disabling Prestart do?

After the service is completed:

• the engine starts without delay
