MAF fault P0100

Hi,
I have a 2009 FL2 2.2 TD4 which has a P0100 fault. I removed the sensor and cleaned it up. The engine management light went out and didn't come on after a 100 mile run. However, switching the engine off and on again the light illuminated again.

Is it enough to just clean the sensor? The filter is dirty, Could this cause an issue?

Thanks.

Could be a wiring fault or a faulty MAF sensor - most likely to be a faulty sensor so I’d try replacing it first

Cleaning the MAP is of questionable use. They degrade with age, so no amount of cleaning will help.
Replace it and see what happens next.
