So what else can cause the indicator, and hopefully the steering angle sensor change will fix it....I'm a bit PISSSED at BMW with the $4-500 repairs now and then on a car with 58,000 miles

And since the STEALERS are such F*****S with their selling tactics, I'll bite the bullet and jusk keep this car.
I think I get irrational about trading up and getting a newer one, our 06 is GREAT, even though it needs "massaging" now and then
We put about 8K miles a year on it, so when it is 10 years old annd the depreciation has leveled off, MAYBE I'll look at upgrading
For now the local BMW dealers can kiss my ass.......
VISTA AND FT LAUDERDALE BMW

Try going to Motronix in Dania. A bunch of coworkers I know have used them with great satisfaction. www.motronix.net They know german cars and are very reasonable for a high end Indy who won't mislead you from wha I've been told.

I don't have a battery charger so got some jumper cables and ran from my E46 (Has 13.6 volts off and 14.2 running) to the E53. With cables in place and the X off, it was getting 13.4 volts at the OBC. Running it was at 13.8. Did this for about 30 ish minutes. (I ran cables to connector under the hood and not battery direct).
Afterwards I tried the steering wheel turn lock to lock a couple times and went for a drive. Seeing 13.8 on the OBC the entire drive. Light still present as ever...

Since your battery voltage isn't low after replacing and charging up your new battery...plus driving around seeing that the alternator/charging system is working...and your 4x4 warning light is still illuminated...the next step is to communicate with the vehicle (BMW DIS/GT-1) to see which sensor is setting a fault for the 4x4 warning.

The 4x4 warning light does have a purpose...it lets' us know when something is wrong with xDrive...as well as illuminating when we manually turn DSC off. Just to check, the DSC button wouldn't happen to be pressed in or stuck from a spilt sugary drink etc?

BTW...just to be sure, your battery warning light is NOT illuminating while driving or staying illuminated, right? I ask because the battery warning light comes on to let you know when the alternator/charging sytem is NOT keeping your battery charged...and thus is the culprit for electronic problems (the battery is the VICTIM in this case, not the culprit).

The battery light never has never been illuminated. Here is my dash currently:



Also, I recently noticed there is a small scuff on the physical DSC button. Like someone hit it with a ring or knife maybe? The DSC worked fine for the first couple months of owning the car.

I'll see if my wife can send a pic of the scuff on the button and i'll post it.

Here is a pic of the scuffed button... Thoughts?

I have a little voltage/battery tester that I bought on AMAZON some time ago, it plugs into the cig lighter and gives digital readings....high when driving was 13.85 low after overnight was 11.74. Battery is about 2 years old provided by CPO warranty.

This is pretty similar to where i'm at monitoring via the OBC.

I don't know about others...but your images aren't visible on my work CPU. Are you uploading them as attachments in your posts...or do you have them uploaded to an image hosting website that has assigned them a URL?

It could also be my employer's server doing net nanny on me if the hosting website is not approved.

Hmmm, at this point, there is entirely too much guessing. Qsilver hit the nail on the head with the battery, but at this point voltage doesn't seem to be your problem. This may suck, but you are going to either have to take it to the stealer to have the code read or a indy shop who has GT-1 to get the code. No time for guessing anymore. Mine came on this morning but also read "4x4 Inactive" on the cluster. After a restart, the light went away. Things like this occur because of voltage. As of now, my voltage regulator is on its way out. But for you, the story is different.

TwinsPoppa had the same problem a few months ago, luckily he has a GT-1 and it spelled out SAS. So he DIY'd it himself. You got to spend a few bucks to get the fault back, but atleast you can stop guessing.

I'm using the image URL after I post them on twitter. I had a buddy check the URL to this thread and he could see them. They are also showing up on my iPhone. Might just be your employers firewall.

I think you're right on this one TwinTurboGTR
Good luck with your light. Mine started like that as well. Would come on then go off after driving. Or just be off the next time we drove it. Happened for about a week or 2 of intense snow driving, then decided it wanted to stay on forever.

I'm going to see what my BMW indi says. Heading out of town so it might not happen for a week or 2..
