it absolutely doesn't lose its registration when you disconnect the battery. i replaced my battery and the issue was the car still had the oem battery as the registered battery. that's why it needed to be re-registered...to let it know that it was no longer the original battery and that it had been changed, not b/c it didn't have ANY battery registered.

That's weird, at least on my car. Didn't have error code, disconnect battery, now have error code. Maybe something else is going on in my car.
BTW, if I "register" battery now, will it analyze my battery as it is now, or will it treat it as a brand new battery and charge it as if it were a new battery? |

I have replaced my battery, with a bigger, stronger one over a year ago, and knock on wood have not experienced a single problem to this day.
I would rather not spend $100 if I do not need to. |

Would the dealership give me a hard time? I've built my own battery consisting of a wooden box with used laptop 9-cells wired in parallel. Would they register it, or do you think they would look inside the box?

This is BS... if the system requires a re-calibration after simply replacing the battery, then the re-calibration utility should be BUILT IN TO THE CAR. It has an on-board computer for chrissakes. It would be no thing to add a calibration menu to the iDrive. Heck, if it's already measuring so many params from the battery then it sould be able to SELF DETECT a battery swap and adjust accordingly. It is just plain silliness to have to make a dealer trip for such a simple operation...

Okay, did some more checking. The error code I got is not related to battery reigstration. It looks like when I removed my battery I broke the blue connector that is the Intelligent battery sensor. Now I need to find that blue connector to get rid of the code so the IBS works properly.

Careful - the last time I posed something pithy in this thread I got a 10 point warning.

Thank you for sharing your experience. If you don't mind, I have some questions/observations:

Yes, and at the same time they cleared the error codes that may have come from the old battery. Can you provide proof that the "error codes" came POST battery swap? Thanks! Last edited by kaigoss69; 10-27-2010 at 08:21 AM.. |

BMW has built a Rube Goldberg machine. http://en.wikipedia.org/wiki/Rube_Goldberg Changing a battery in a car is one of the simplest maintenance tasts that one can do; only slightly more complex than refilling the windshield washer fluid. I like to do the minor maintenance items myself - change oil, change air filters, change the battery, etc. Quite frankly, after reading this thread, I fell less comfortable doing any type of maintenance to the car due to unintended consequences. This is the final nail in the coffin for me; I'll likely sell my car when the license plates are due for renewal next year and either go with a Cayman S or 911 (yes, Porsches are huge maintenance beasts, but I know that going into the purchase). My wife was going to get a BMW as her next car; after seeing the hassle that I've been going through to get BMW to warranty replace my battery (I will have to sue BMWNA in small claims court), she is now sold forever on Acura. In my humble opinion, BMW is destroying their brand name. It's too bad; it's a nice driving car once you get rid of the run flats. |

As I have posted before, I use a portable voltmeter to check the charge rate. It has been a consistent 13.7-13.9 volts since the car was new. When I have to replace the battery I will check to make sure the charge rate is the same. If not, I will probably have it registered. It will be a cold day in hell if I ever pay $400 for a battery for a BMW or any other car when I can buy one from Auto Zone or Walmart for $77.

ShastaMan, I think he's referring to the battery being in the trunk of the car vice under the hood. I consider that (putting the battery in the trunk) to be another Rube Goldberg feat of engineering.

Not true, you just have to make sure you connect the vent tube.

If no codes are being thrown use Chevron Techron fuel injector cleaner (concentrate). It solves rpm fluctuating upon cold start-up. Also, for most BMW problems start off by scanning your car with the Peake Research Tool. It contains the actual BMW codes. If you want to register a newly installed battery for free (just buy a $10 cable) and google/download BMWLogger

Neither did the registration process fix any errors. They just cleared the codes that were there (probably) from before the battery swap. I think we are back to square one. |

It is actually for weight balance and moment of inertia chassis design purposes, and an added benefit is the battery is subject to much less vibration and temperature extremes. It's been a design philosphy of BMW for at least 35 years now.

under normal use you will have to change one battery during the life of the car. probably the car has cost you $50k in depreciation and maintenace/repairs by that time. even if you pay $200 premium for dealer installed battery it might worth it just to avoid potential problems.
