Thanks for your reply Paul on this issue .....first of i drive to work 20 miles each way ..10% A roads and 90% motorway and because i start very early in the morning i will hardly ever use stop/start but ive paid Citroen for a car that is equipped with it so i want it working 100%. Funny you mention the battery because if i drive to work (20 miles) and im to early for work i would always sit in the car park and listen to the radio with everything switched off but in the c4 i only get 2-3 minutes of radio then it goes into economy mode and the radio turns off and i can't even use the electric windows...when i mentioned this to the fella on the service reception he said he thought this was normal ...someone please tell me he is talking BS ,he said if i want to listen to the radio i would have to keep the engine running ,i told im it was not 1960 ..talk about getting fobbed off. Paul please tell me this is not normal.!!!! PS having trouble putting in an avatar ...help lol. Regards Mark.
