Hi there, I have a 7 day old C4 Picasso 1.6 HDi VTR+ when I collected the car the ECO system worked fine. However 3 days later it stopped working so I booked it in to the Bradford Citroen dealer and was told that the ECO system would not run whilst using any repeat any of the heating or cooling settings this meant that everything including the fan had to be off for the ECO system to work now Plugging in the computer it had an array of errors, mainly brake issues, the internet suggested it could be a supply wire for the abs/ esp computer, it had been changed previously and had a beefier fuse than the original, slightly suspicious so off came the front left wheel, and inner liner and some previous owner had fitted a plastic bag Hello. if your that concerned get the battery checked, most motor factors will carry this out for free. And make sure that when the battery is bad you get the right one. Lots of people have been sold a battery below spec and you will continue to have problems as the electronics are sensitive to this. Joined: Mar 22 2018. Location: Epsom. I have a C4 Grand Picasso (08) which has developed the 'multiple warning light' fault, which seems to have many threads, in various guises, on this forum. At the same time it also goes into limp/safe/downgraded (not sure if these are even the same thing) driving mode. Having sifted through the forums for I have citroen GRAND PICASSO C4 2015 diesel 2.0 Hdi with two technical problems: 1. The first issue is that the start & Stop system suddenly stop working, when there is a sign of a clock near the "eco" image. You can see an example with a picture number 1 foR that problem. Is anyone know what the is the sign of the clock next to the ECO and why Don’t forget they use the new start/stop battery, AGM battery quite pricy, at GSF online after discount code ended £69.50. I used my reg 2015 2.0 change your reg and see the price might be cheaper if it uses smaller battery. - Click Here - Or maybe try local auto shops might give you better deal? 9jKNVz.
