had my f typed smoged aprox , in about 100 miles the battery showed low , charged it and all was fine , checked my obc later the same batt low showed up , so every time i use my obc to clear or chech codes the batt show low a few drives later any ideas ??

 

disconnect the battery for a minute or so. that should solve the problem assuming that the battery isn't toast.

 

thanks have done that in the passed ,will try again

 

you aren’t backing out properly after connecting which means battery still discharging. Disconnect earth in boot for short hike. Loads of threads on here about it
