1. Charge battery.
2. If it does not hold charge, replace it.
3. Old trick: Remove tops of battery (if possible).
4. Turn battery upside down in a large plastic container.
5. Lead flakes will fall out.
6. Refill with water and charge on trickle charger.
7. If you are lucky, battery will hold charge for 6 months or so with regular use.

8. Much simpler to replace battery.

Most batteries fail after 36 to 48 months.

Just got "Increased Battery Discharge" error code a week ago. When it started it was interrmittent. Took it to the dealership and their diagnosis is I either did not turn the car off properly (shut down all the accessories) or have somehow left the fob in the car -- I have comfort access. I informed them that neither is the case (since having owned the car for a long time, I did not just developed a case of brain fart), at which point, the dealership request to keep the car overnight to confirm my claim. The next day, I received a call from the dealership that I have come pick up my car, and eventhough they can not show that it was my fault, their "computer diagnosis" is giving them the error as "operating error" and thus they can not submit a warantee claim. The dealership generously offer to charge my battery, so I can take it to another dealership, or pay $425 to have them replace the battery. I am not even sure the battery is the cuprit, because I told the dealership that even after I properly shut off the car (push and hold start/stop button until all off, AND lock with fob) I can still hear the cd/dvd/cd changer doing things and making noise. I have a call into BMW USA right now, but since the dealership forced me to take the car back I am in a constant state of fear of being stranded somewhere due to dead battery. This sucks, on a fr**kin 2007 530i with comfort access. Anyone with any reccomendations or update to this issue?

If you have to return the car for the same issue for 5 times, isn't there a lemon law to deal with this?

Hi,

This morning my car died because my wife left the lights on last night.
I jumped the car and car started but now I am seeing all kinds of triangle warning on my idrive. Is there anyway to fix this? thanks in advance

Finally, after a week's worth of phone calls to BMW NA, they informed me that the dealer will replace the battery under the "goodwill" clause. I am happy that this was done, but was dissatisfied overall. 1. the dealer made a big deal out of this "goodwill" thing, although I can not understand why they would put their customer through this for an 07 530i that was decked out ($60k+) over a lousy battery that failed in 2 yrs of ownership. 2. They replaced the battery, but failed to do the Energy Diagnosis at time of battery replacement, even though I showed them the SIB that dealt with the R15 error code they found in the car, telling them that this should be done to properly diagnose the problem.3. It has been a week since the replacement, and now I once again notice the car failing to shut down properly, even though I follow proper procedure absolutely (the car has Comfort Access) -- the cd player wirls away happily even when all else stopped, and sometimes the cd changer cycles the discs. Today, the passenger restraint error code comes up, so I will have to bring it in again, and hope that the service advisor will listen to reason, and check the car properly. Otherwise, I have a feeling I will be back for another round of battery replacement woes, with endless dealer nonsense and grief. Dissapointed in So Cal.

Thanks so much for the tutorial. I bought a replacement battery at Batteries Plus for $190. It is identical to the original. They use to have Werker, they changed the name to Rayovac.
I replaced the battery in about 45 minutes (i was extra careful because I did'nt want to electrocute myself)
The battery was disconnected for about 4 hours (had to run some errands and pick up the new battery).
When I hooked up the new battery, there were no errors in the Idrive. All my presets were still there. All I had to do was set the clock.
Hopefully nothing comes up in the future.

BatteriesPlus didn't have a Werker 95R. They only had a Rayovac SLI95RH9 for $189. It is an exact duplicate of what was in the car and is labeled as "Made In Germany". I haven't had any problems since the change out on Sunday.

Thanks again!
