errors dtc on the Espace iv 175cv edc16cp33

[Errecinque]

Since mechanically they are a little ignorant, I ask you this. The machine turn on the mil because of dtc DF209 and DF647 (attached the screen) . Since I have difficulties to find the right method to delete from the map management the egr, if I make the switch off of these 2 dtc, according to you I solve the problem? In the sense that if I turn off the light on the dashboard, and mechanically I leave the valve as is what happens? Thanks

What are the descriptions of the errors? The valve is open or closed?

You eliminating the management and excluding the dtc from the map, you should resolve 99%. Please contact the service of the forum.

Seems to have broken the electrically the valve,I had an experience resigned on a bravo 1.6 mjt and gave me the stereo errors.replacing it resolved and I opened the old, out of curiosity,in practice, the valve had the charcoal of the contact wear on the control position and therefore was not driven to duty...back to us, check if it arrives correctly to the power supply,if it is ok to escludila from the map, but check the mechanical locking.

Sorry, but the auto-corrector of the phone has the correct evil number of words,I wanted to say 'similar experience' and 'gave me the same errors '

If you do not want to lose time, see, first, the fuses as you have suggested, if they are ok, proceed with the exclusion of this valve from the ecu and then exclude also the dtc. If you can't do it directly yourself, please contact the online service of the forum.

Thanks to all of the advice. As soon as I have the machine available to try with the fuses if not seen that it is of my best friend do a bit of testing with the exclusion from the map. The maximum I leave it to the foot.....
