A video from a guy who also tried two CTEK to charge his Mild Hybrid Technology vehicle was unsuccessful.
You can CC the video in English if you need.
I still have a problem connecting a 20 Ah charger to my battery. This will push a lot of current and charge the battery faster but that is detrimental to battery life. Plus, my annoyance is these chargers (Ctek 25 and Noco 25 are HUGE!)
Funny, this guy was told by his dealer to charge it with the bonnet closed....
I heard many people complaining and nobody knows the answer. The dealers are worse as the don't know not even as much as we do
BMW should be ashamed for staying quiet in this one!
