RENAULT MEGAN II SERVICE FOCUS

I just made me megane a complete tuning, but not in the agency, and the mechanic that made the tuning could not turn off the focus of service, something special is needed or I can do it.

greetings

By service focus, I understand that you mean the service light that remains in the table.
If any injection sensor is disconnected, ignition, temperature ... with the battery connected, it understands it as a breakdown and marks it in the box to go to the workshop to repair it.
For that you have to connect to a machine (computer) that reads the mistakes and deletes them. Many workshops have it, not just officers. There are cars that can be reset without a computer but Renault I think no. Ask, I don't think they charge you much to reset it.

Forget, you can't do it without a machine.
