🎨 Citroen C4 Picasso Display Not Working
» Addition of the RD5 ECU for the Citroën DS5, DS4, C4 II vehicles. Update 6.39 / 7.06 includes improvements and corrections, in particular: DiagBox Version 7.10: 1. Opening of the vehicle points of entry for : – Citroën Berlingo Electric (B9E) – Citroën C4 L (B73R) – Citroën C4 Picasso (B78)2.
I wonder if the system will actually restart if the touchscreen icons are used. Press the 'driving' button (the one that looks like a car), use the button on the far left of the new screen to bring up page 2, then press the 'Eco off' icon. The yellow bar should go off, the 'eco off' icon on the top screen should go off, and the stop/start may work.
To flush the whole system do the following: Remove the feed hose before the "T" (under the bonnet) and run the pump for 5-10 seconds. Reconnect the hose to the "T" and disconnect both outlets. Run the pump and observe if both sides give the same amount of water. Reconnect the two hoses to the "T" and disconnect them from the jets.
Once you have pulled the camera and it's holder forward you will see a cable plug on the back of the camera, just unclip it and spray the contact cleaner into the cable plug end and of the camera plug, leave for 5 minutes and then refit in reverse of removal, your camera should work again. Hope this helps.
