Citroen C4 1.6Hdi - P0243

Unread post by Zelbra »

Hopefully someone can help with the wiring on my
son’s Citroen C4.1.6Hdi 2007. I couldn’t get the wiring info for this specific model around the internet!
Lost the power Diagbox fault code P0243.
Replaced Turbo pressure electro valve. Checked vacuum lines and the rest including turbo itself.
I believe it is a wiring issue.
Does someone know where is the wiring from the turbo pressure electro valve ends on ECU?
Any info much appreciated!
