I have checked the voltage on the battery. It's at around 12.5-13 with engine off. When I switch the engine on it doesn't change very much. Does this point to the alternator?

Thank you for that. I do take a lot of short trips. I will check those things. Thanks again..

Hi. I'm new here and am currently finding my way around. I have had my C5 diesel auto (2010) for over 3 years now and have had absolutely no problems at all with it until now. I love it and only regret I never owned one before!!! My problem is relatively minor but is having a massive impact on my fuel consumption. I'm finding that the stop/start feature (it's an E-hdi) only seems to work from time to time. Due to the winter temperatures, I thought it might be something to do with the cold. Now the temperatures have risen it seems this is not the case. Is there a fix I can perform to sort this out or is it a visit to the dealer? Thanks in advance for any help in this.
