The key fob button which turns the lights on, which with xenons is great quite often won't work because economy mode has already activated. There is a software update (Inforapid) which I had done on my car last year. It improved things marginally but nothing to write home about. I have a Citroen C4 Picasso 1.6HDI year 2014 with just over 16k. The engine code is DV6C automatic. A few weeks ago as I stopped on a motorway exit slip road the car went into limp mode. The instrument panel lit up light a Christmas tree saying ESP / ASR was at fault. The maximum speed was 20 miles and radiator fan continuously was running Posts: 87 Threads: 18.

One wiper go in one position and stay there, another one just want to move, but nothing else. I take all apart but don't find fault. And John, disabling the ECO mode on my Picasso does prevent the problem for that journey only, because it resets itself every time you switch off. And unfortunately the disabling process is not that simple on the new Picasso because you have to go into the computer's vehicle settings to do this - which means you have to be stationary to achieve it. It doesn't make any sense. Eco mode only shuts off uneccisary electrical consumers, sidelights may be neccisary (depending on where your parked), if you notice the hazzard lights still flash but the telltale lights & noise stop inside because they are not needed. I understand Economy Mode and the reasoning behind it but am intrigued as to why it is activating post radio replacement and since the cold weather in coming will the repeated activation of Economy Mode cause battery problems? I only cover 9 miles per day and am worrying about flat battery You get a few years of free map updates with this car and also software updates are available. To get the updates do the following.
