When something isn't working properly, there's a method that often proves foolproof: turn it off and on again, unplug it, and plug it back in. And everything (maybe) will be fine. This is also the case for many BMW owners who plug in their car to charge the batteries and the charging session doesn't start. Before panicking, the user unplugs it, waits a few seconds, and then plugs it back in: everything works normally. BMW only starts charging after unplugging and reconnecting. It's difficult to explain the reason and provide a logical explanation. While it's true that the problem is solved, honestly the solution is only apparent. Why doesn't charging happen when you plug the car into the charger for the first time? We usually think it's due to poor contact between the plug and socket, as if the connection isn't working properly. In reality, this isn't exactly the case, and it's difficult to determine whether the cause is the wallbox or the cable. Our advice to you is to try at another location and, if there is no further confirmation, you could try another cable, choosing, for example, from the Voldt BMW charging cable.
