Citroen C4 stop start / E HDI Lin issue

Unread post by kewlnsol »

Hi workign on a citroen C4 picasso, E HDi with stop start - bought recently, fr.2 icarsoft reading Lin U1133 and U1134

So wrong battery was fitted previously now fitted new stop n start compatable battery.

Wiring looks odd to me the wire with yellow insulation marker on comes off the 12v post when it looks like it should come off the terminals to the right of where its located, anyone have images of a 2012 stop n start auto 1.6 by any chance? diagram would be useful too

Have a look at this video - exactly the same part number 28236841 as your car and a clear view of the wiring layout, along with testing and fault resolution in this case.
