Hi Everybody,
I have this Error Code:
P0404 - Exhaust Gas Recirculation Circuit Range/Performance

Google says that I have to replace the EGR valve, but actually I need to know first if it is really damaged.

Does anyone know if it is normal that I am unable to press down the valve?
Because I already watched some videos in youtube showing the way to clean the valve, but those valves in the video can be easily pressed down, and I cannot press down my valve (I don't know if it is activated by electrically)

Thanks in advance,
