renault master problem

[pinheiro]

Hi friends

I have a problem with a Renault Master II 2007, 2.5 DCI, 120 Cv, Engine G9U/750.
The car sometimes doesn't pull, When we accelarate, the car doesn't develop.

By diagnostic the code error is DF056 (P0100) Air mass sensor.

My doubt is that this version hasn't got any air mass sensor.

What could it be?

Thanks in advanced and regards

You have right ,your car doesn't have mass air flow ,can ignore this trouble code but you can check the rail pressure and the fuel metrring unit ,injectors.If you can send me some live data mabe I can help you more.
