08 E92 M3 w/ "Increased Battery Discharge" warning

57Strat · 11-18-2011, 02:09 PM

Every time I start the car I have to reset my clock and there is a warning in the VEHICLE INFORMATION display that says "Increased Battery Discharge". I drive the car every other day for at least 30 miles, and my drivng habits have been the same for the last year or so. Is this a known problem?

sounds like you need a new battery...

I've had this issue recently. They determined that the gear shifter was draining the battery. They also replaced the battery since it was drained abnormally. Hope that helps.

How does a gear shifter drain the battery?

DCT has lights on the shifter to indicate the D/S etc.

When the car is turned off?

If there's a fault in wiring.., it happens.

I just had my battery replaced. Same problem with the car not starting etc.
Call your SA and get the car in for service. It will not go away, or even start.

I just replaced the battery in my '08. Similar type problem.

Same here. Just changed the battery under warranty ~18K miles.

socalbreeze · 11-19-2011, 04:57 AM

Just got it today as well. So they'll replace the battery for free?

Make sure your remote keys are not in the range of your car over night.
If your keys are near the car overnight, your car is always in standby mode which drains battery.

Here's the thing. Nothing has changed in years where my keys are stored or where my car is parked in my garage. Nothing has been modified on the car or any equipment added. So the problem has to be caused by something going wrong with the car. I am betting the battery is simply beginning to fail and I need a new battery. Although I admit I have never had a battery in a car fail at 3.25 years. Usually it is 4+ or closer to 5 years before the battery fails.

My SA siad it was likely due to low mileage since I only drive ~20 miles a day to work. If this was the case, the new battery would be off warranty but he did me a "favor" and charged it to the warranty for a "bad cell."

Driving your car ONLY 20 miles a day is not enough to keep the battery charged??? I can't believe the SA said that with a straight face. What a crock of schit.

Which dealer did you got to? I'm having the same problem and Shelly BMW is refusing to cover it under warranty because " I don't drive enough mile" in a day.

My dealer told me same thing. You can request them to run overnight test for battery drain issue to figure out if that battery issue or not enough miles to re-juicing issue.
