For those you you who have the Stop & Start feature on your car, does it work as expected? My 2015 C4GP worked as expected for a while but hasn't worked now for long time. Thinking it was because I didn't regularly use the car on long journeys, I charged the battery. The charger said the battery was fully charged, the Eco light on the dashbaord flashes when I come to a halt, but it doesn't cut out. I am hoping that this Start/Stop is not some sort of scam like the VW emissions issue and that the Eco function only works for a time. |

Mine still works after ~26,000 miles. There have been a couple of occasions when I wondered whether it was functioning, usually after it hasn't run for a couple of days. There was one occasion when, despite having driven round the local area for 2 or 3 hours, the system wouldn't work, so I decided to go to the agent. Of course, Murphey's Law applied, and on my last stop before the agent the system started to work again. So, now I don't expect the system to work when the engine is cold, and I don't expect it to work for a couple of hours after the car has stood still for a couple of days. There are certain conditions when it doesn't work, but the only one I am certain of is that it will not work when the outside temperature is 35 degrees or over. Similar applies to our C3, which although fitted with stop/start, is a different system to our C4GP. |

Mine working fine but at this time of year it doesn't cut in as often. Lots of variables affect voltage and current demands, so if aircon, fan, headlights and so on are drawing lots of current even if voltage is OK it doesn't stop. At this time of year headlights and heater fan are usually working hard for a lot of the day. |

Mine was not working at all, just flashing green ECO when stationary, I had the battery tested and it was down to under 60%. Spoke to Citroen who said that the battery needs to be 76% or above for the system to work (this is not charge but is the % left compared to when new.) I had the battery replaced and the system now works all the time, I presumed that it would not work if the engine was not up to temp but that is not the case. I know some people will say they don't like it but I drive in to London every day so it makes a noticeable difference to my consumption now it is working correctly. Richard |

Quick question then regarding batteries: How long would you expect one to last? Our Pic is now 4 years old. Cheers, Matt |

I've usually found OEM ones to last up to 6 or 7 years before they start to get "sluggish", though some soldier on a little beyond that After that, it depends on what you're willing to pay ... inexpensive ones get a 1 year warranty, and are usually toast by year 2. High end ones aren't that much more expensive up-front, but come with a 5 year warranty (keep the receipt, they usually only last 4 in my experience!) |

Mine works when engine is cold. I don't like it and turn it off at start up every time. It is too quick to turn the engine off, so when you approache a roundabout and lift off the throttle only for a second the engine cuts off and then it has to restart it 1 second later... silly. When is the UK warmer than 35 degrees? LOL |

You are right about the 35 degrees in the UK, but it has happened to me 2 or 3 times on the continent. It is noticable particularly if you have been parked in the sun, when the temperature recorded can be very high, then it drops rapidly after you drive away. |

The e-HDi models with EGS/ETG have the issue where it cuts the engine at low speed (ie the automated clutch has disengaged) even if it was never your plan to come to a stop - that would drive me nuts | ||||
