This has only started happening a few days ago. I've got a 2017 (facelifted) Flair. It's not immediate (i.e. if I turn it off and back on it's fine) it seems to happen when the car has been off for a few hours or overnight. Is the memory battery powered? With the current times, I'm only using the car for 20-30 mins per day (2 trips). It started about 2 days before my warranty ran out, but I have taken the Citroen extended warranty for the next year. |

Sounds very much like your battery is toast / drained .. it might survive a good deep recharge, but I'd be planning on replacement if it does it frequently (especially with frequent very short hops, big load starting and very little charge being returned to it) | ||||

I've had the car 13 months and never had the stop start work (the light on the dash comes on when I stop at traffic lights), the dealer said it was because a. the car had been standing at the showroom and b. i hadn't driven it far due to lockdown when I asked about it after having the car a few weeks. |

I wasn't aware there is a battery in the ICE. | ||||

The car battery has to be favourite. Do you see the Economy Mode warning often? | ||||

If I'm waiting for my son at school and turn the engine off, the economy mode comes on after a 3 or 4 minutes. |

If the battery is bad enough to make the radio forget, then you are lucky to have it start then engine. | ||||

Time for a professional battery check with a new battery likely. With a new, fully charged battery, you will get the max 30 minutes before Economy Mode kicks in. |

Something that might be worth testing is if you have any radio presets do they stay on the screen after a few hours or do they revert to being empty? If they stay it might be worth trying to set the station you are listening to as a preset (press and hold on radio icons) and then start the car after a few hours to test. Assuming you haven't already tried that. Seems unlikely it would be the battery itself because the car starts fine but not 100% sure on that one. |

There are two feeds to the radio, one permanent and one switched. The permanent one keeps the memory alive the other switches the main radio circuits on. It would appear that your radio is getting very little power from the permanent live feed. As another (2nd) issue you seem to have a failed or failing battery. A good condition battery should last quite a while before economy mode kicks in. I have just changed our cars battery as stop start hadn't worked for 12 months that we have owned the car. Stop start now works all the time and haven't seen economy mode at all. The battery on ours was an 096 AGM battery although some cars have an 027 AGM battery. I purchased from Tayna batteries at £90 something pounds delivered for an Exide battery which was over £400 at Eurocarparts. There are lots of videos on You Tube how to change the battery and if yours is the 1.2 puretech version I have posted a 'how to' about changing the battery on this site. Hopefully fixing the battery will also fix the radio issue. | ||||

Just spoken to the dealer's service desk on the phone and they're saying they think it's a software problem, that the head unit needs it's software updating. It's due to go in next week, but a can't imagine how it's a software problem (oh, and it's not covered by the warranty so it'll be £106 thankyou). |

It's possible that the Quadlock is not fully seated, causing a faulty/weak connection of the live feed. Pull out the radio, disconnect the Quadlock, clean with toothbrush and replace, pushing home firmly. | ||||
