I used a CTEK MXS 5.0 Charger on my 330i and charged my vehicle for 15 hours but the charger only got to stage 4 during this time. The downloaded Software Update will still not complete!
I have only selected normal charging mode (Car and AGM LEDs lit). Should I select ‘reconditioning’ mode as well?
Should I leave the charger to complete its 7 stage cycle or could it be faulty because it hasn’t completed yet after 15 hours?
