xtr041947 0 Report post Posted July 2, 2019 Hi Guys, I have an M5 (F10) 2012, my stop start feature doesn’t seems to work. A common suggestion on google search suggests charging the battery. Could anyone recommend the best charger to use on my car? Thanks in advance. Quote Share this post Link to post Share on other sites
balancerider 702 Report post Posted July 2, 2019 The stop-start won’t run if the engine is cold or there is high electrical drain (aircon on etc), but often suggests a battery on the way out (or disabled by previous owner) if it never works. CTek chargers have a good reputation Quote Share this post Link to post Share on other sites
Gaz 1042 Report post Posted July 3, 2019 There are around 25 criteria for the car to meet before it will turn off but low battery charge is one of them. Most people are thankful it doesn't work so embrace it haha Quote Share this post Link to post Share on other sites
