BMW i3 range extender not starting, not repaired on BMW i3

Some BMW i3 owners report experiencing issues with the range extender not starting, which can lead to frustrating situations when the vehicle's battery charge is low. These problems include the range extender failing to activate at expected battery levels, resulting in reduced power or complete stops. Additionally, some users note that automatic maintenance of the range extender may only occur when the battery drops below approximately 70% charge and that a minimum amount of gas is required for this maintenance cycle to function. Owners have also reported that problems with the range extender can affect vehicle acceleration when transitioning from battery power to the petrol engine, with some suggesting that a software update might help resolve these issues. Furthermore, in instances where the range extender does not start or shuts off unexpectedly, users have encountered error codes such as Misfire1 and Misfire2, prompting troubleshooting steps like changing the fuel pump relay, spark plugs, and testing coils and injectors. For unresolved issues, consulting a BMW dealership or a certified mechanic specializing in electric and hybrid vehicles is recommended for proper diagnosis and repair.
