Did you delete the fault code? How old is your battery? Could mean you need a new stop start battery, over time it will gradually deteriate and when it has deteriated to a certain level the top start function will no longer work until battery replaced. |

Hi I have replaced the battery with a new AGM stop start battery before changing the capacitor. Is there a fix for this problem. | ||

I have deleted the fault code but it comes back after the engine is switched off. | ||

Do you have to tell the car you replaced the battery? I know with BMW stop start batteries the car has to be reset that a new battery has been installed. |

Hi I am not sure my C4 has been on a scan tool twice and they and they have told my car has Error P1A9C after changing the battery and replacing the capacitor. Do you have to tell the car about the accumulator capacitor has been replaced. Nobody can seem to tell me that yet. |
