Battery low warning

Now I don't know if this is true or not, but a CA once told me that other BMW key fobs can wake your car. Because of how the handshake works (and I'm not sure if this is *all* cars or just the ones with CA), if someone else unlocks their BMW, all BMWs in the vicinity also 'wake up' to see if it is the correct key fob, and when yours sees that it isn't, it doesn't respond and goes back to sleep, but nonetheless some of the electronics do wake up momentarily. He said they have issues with the cars on the lot because of how often these little wake/sleep cycles occur. Could be BS, could be true, but sounds plausible.

yes, ~15 minutes for cars without bt, ~30 min for cars with bt (IIRC)

cars without the tcu module go to sleep in half the time (approximately)

not sure why the tcu module extends the deep sleep time

Other problems are not relevant to the thread.

And, yes, I had known about them and asked them to be addressed.

Yes. We have an ironclad rule about diverting from the original topic.

Its ironclad when it requires me to list a bunch of minor problems I have no interest in discussing!

But, apologies to Wihelm G if I came off rude there. It was nothing worth discussing, just some minor rattles and such.

Deleted.

Only kidding...I always bow to Orient and Wall Street. Just glad it was a simple fix (couldn't believe a bat. would go out that soon).

Your dealer will handle it.

Tom

Oh... had it replaced at local batterty shop

bummer

There is also software that allows you to do it with your own laptop.

Otherwise, you need to have a dealer or a BMW specialty shop do it.

Good luck and sorry you have had a problem.

can someone please make an iPhone app to register a new battery for my car

Please

Am I in trouble ?

went to BM dealer asking them about register new battery... they said non genuine battery they won't help me

they only recommend genuine BM battery

non genuine $165
Genuine $353

what choice do I have

Give up the non genuine and go for genuine and waste $165 ????

A coding cable should cost around 100 bucks at most less if you have an 06.

For info on how to do it go here

this will also allow you to reprogram the car and do diagnostics.
Also and Indy BMW shop may be able to do it for you.

Good to know arrogant BMW dealers are not solely in the US!

My local indy shop will do the registration for way less.

SilverX3:
Go to a good independent BMW shop but call them first and tell them you need your battery registered.
Coding cable and software is nice but that is all you need. Maybe 50 bucks.
More than likely you have the wrong CCA too but that isn't as big a deal as BMW makes it out to be.
Coding can adjust the CCA too but BMW only has so many choices and what you had installed is most likely not one of them but close.
Remember it is a battery and the only reason for doing the registering is to help prolong battery life.
However from what I have observed on most BMW forums it has not helped much.
A battery tender helping 500% more than registering your battery...

OK... thanks for that

Rang local independent they said they can register it for $50 labour

will bring the car to them
