¡Gracias!
Encontré un foro en donde dice que se enciende la luz testigo del DPF al darle contacto (abajo a la derecha del tablero):
"If your truck is auto Euro 4, it will almost certainly have a DPF, if it's manual it's very unlikely to have DPF.
An easy way to find out, turn on the ignition, do you see this light on the dash (bottom right of centre):"
"If you see that light, you have a DPF, if not, you don't."
