Hi Guys,

I am just looking for the symptoms of a dying battery an E82 135i.

Every now and then it does not want to crank at all... This is especially true when the engine is hot. Or when it's cold early in the morning. I assume that's when high cranking amps are needed.

Once it cools down, I can get it started on 1st or 2nd try.

My car is an MY09, does not have iDrive, and I'm not seeing any errors on the dash display.

Is this the battery on its way out? Or is it the alternator?

Car has about 85,000 kms and I suspect this is the original battery!!

Thanks for your help.
