Mein Auto: 2006 330xi
changed batter on 06 330xi... one loose wire

i just replaced the battery on my 2006 330xi. After replacing it, i noticed one wire/connector that seems to not have a place to plug into. I checked the voltage regulator and it appears everything is connected up and there are no open connectors that the loose cable/connector could connect to. see the attached pics. On a different note, i saw quite a few posts saying the battery replacement requires a computer set to introduce the new batter so I called the dealership and talked to someone in the service department. He asked what year and series my beemer was, and then told me that there is no need to bring it to them to do anything to the computer. Based on that information i went ahead and replaced the battery by myself.

please see the attached links to the pics of the battery and loose wire after replacement.
thanks!

The wire is a vestige of shipping, connected to a LED that runs under the rear seat to keep tabs on the condition of the battery during transit.

The battery does need to be registered. Whoever at the dealership who told you otherwise was wrong. A good BMW Indy mechanic should be able to do it.

thanks for the reply. apparently my issue wasnt the battery after all. The reason i replaced the battery is because a battery said it was faulty and then this afternoon my car wouldnt start. the engine wouldnt even turn over. I even has a tow service come and try jump start me and he couldnt get the engine to turn. it was completely dead. Only a few lights came on the display. So as a last resort i disconnected the negative on the battery and let it sit for about 15mins then i reconnected it and the car started. So i drove to the parts store and picked up and new battery and put it in. The car started fine two or three times after that so i drove home ( a couple of miles) and later on i went back outside and tried to start the car. Same issue. Dead. with only a few lights on the display. The interior lights and all other lights in the cockpit see to work but nothing as far as ignition or engine lights. The radio also comes on. Error or warning lights.

I have included another pic of the lights i see when i press the ignition button. If i hold the ignition button in, the lights will stay on for a few seconds then go off. Then i press it again, and the same lights will come on for a few seconds and then go off again.

see attached image.

What is this vestige? Where do I get the vestige connector? Is it under the rear seat?

I will register my battery but my dealer is far away. Can I do it by mail?

If you get a coding setup or Bavtool you can register.

If you get a coding setup or Bavtool you can register the battery.
But I doubt that is what is causing your start up problem unless the
battery is already low .
First monitor the battery voltage to make sure its high enough.
Another trick is to dissconnect the IBS Sensor since this can sometimes stop
the car from starting.
Also most Independent BMW shops can register the battery if needed.
The coding setup or the Bavtool can read stored error codes which would have
been a good place to start.
Its also possible you have a parasitic drain on the battery causing it to go flat
even when just sitting. Have you recently installed any aftermarket equipment?

http://www.bawarec.ru/manuals/3er/e9...3er-e90-12.pdf

Read the above to get a handle on the electric system and to locate the IBS on the
Battery distribution block.

There are articles on y tube for isolating parasitic current draws.

O get a Volt/ohm multimeter if you don't have one.

Check the battery voltage static and running should be 12.6 static and 14.3 to 14.5 when running .
If it isn't above 14 when running its the alternator or charging system.

Also if that is the new battery you put in it doesn't fill the space which is usually the case
and that indicates the new battery may be of a smaller capacity than the one that was in there.
Did you match the amp hour rating and CCA when buying a replacement battery?

On the 06 cars there is a debate as to the need for registration , I don't think it actually needs it.

IBS is the blue plug on top of the battery distribution block that has the wire going to the negative terminal on the battery( attached pod is the IBS Sensor.)

turns out it was the IBS ... it going to cost me 572$ since i had the car towed to the dealership and its sitting there. I wasnt aware that i could disconnect the IBS and start the car. Is it possible to actually drive the car without the IBS? And to the guy who said the dealership is wrong about me not needing to register the battery...turns out an Indy BMW mechanic told me the exact same thing... 2006 Beemers dont all need to have the battery registered. I am hopefully getting my car back today... i will post back on the end result. thanks!

Hi, just an update, i talked to two separate BMW mechanics and both told me the same thing... 2006 is an iffy year and not all 3 series BMWs manufactured in '06 need the battery registered... im taking mine to an indy shop as soon as i get it back to let him definatively tell me if i need to or not...

Isn't there a recall on the cable or is that later years?
