My wife's '08 328 with 34K miles has begun slow cranking. Batt measures 12.2V at rest and 10.1V while cranking. I compared to my 2010 335 and I can tell her battery is on its way out. Took it to dealer and they tell me it passes BMW's battery test. They cannot replace under warranty. Argh!!! I suppose BMW wants customers to wait until its so dead it won't crank the car over. Lovely!
