Has anyone come across this? After bringing it in for an oil change and alignment, My BMW (X6), had an unusual battery alert. That has gone away, but certain electrical aspects are fading. I now have to put the fob in the ignition to start the car. The radio/cd/Bluetooth doesn’t link/work.When I back up it indicates “ no tones”. It seems to run fine, but I’m wondering if it is utilizing the power in the battery and the alternator is faulty and not providing the recharge when I drive? My guess is some of the electrical features, see above, are not functioning due to lack of power. Or perhaps the battery is shot? Any insight would be greatly appreciated.

Might be as simple as the techs leaving doors open, radio on, etc., while completing your service and now your battery is drained. I would think putting a charger on it would most likely remedy the issue. I don't know how old your battery is but that could be one of the factors as well.

Powerless?

I see you've joined with your first post - and it's a sad one ;-(

I recommend you begin your participation on the forum by using the search function - many of the usual BMW "issues" are covered in posts that could give you a hint about the cause of yours.

I suspect what you've just discovered is a "battery issue" - but without more info it's only a guess. What year / mileage on your X6? New to you or a recent acquisition?? Do you have basic tools and DIY experience? E.g. Do you have a VOM to do a simple voltage check on your battery? etc etc. Is the battery a AGM or flooded type? (Do you know?). etc etc. Do you have or know how to access your owner's manual (https://www.bmwusa.com/owners-manuals.html )

The electrics/electronics of newer BMWs are complex - doing the 'old shadetree mechanic" stuff can make a simple issue a real problem! E.g. connecting a basic battery charger to the incorrect charging location (battery terminals = A NO NO !!)

SOoooo Happy Sunday - good luck with your next steps.

X6, battery/alternator advice

Might be as simple as the techs leaving doors open, radio on, etc., while completing your service and now your battery is drained. I would think putting a charger on it would most likely remedy the issue. I don't know how old your battery is but that could be one of the factors as well.
Thank you! I bought the X6 in 2014. It was a leased vehicle before I bought it. It was CPO and under warranty for a while. I have never changed the battery, but was assuming it was a battery or alternator issue. While under warrany they replaced the driveshaft and there have been some other recalls. Sounds like the battery replacement can get complicated, so I will regretfully bring it to a dealer ( expensive and not very knowledgeable in Florida) . Any tricks/tests one would recommend? Ie: should I have them check the alternator? I am always cautious of just giving the dealership the green light to take a look and fix. Am I overly paranoid? Thanks for the help with your insight!

It is not difficult but you do need a BMW specific scan tool to complete the registration. Enter your vehicle information into Newtis.info website and you can find the steps to become familiar with it. Also Google it. A good independent shop will only charge 1-1.5 hours of labor + the battery. I think the dealer would be even more. I personally would rather pay $150 or so for a new battery and do it myself rather than pay someone else $400+. I don’t consider myself a battery expert by any means but if you read through several threads here you will see similar accounts.

Update/ thx

Had a new battery put in. The car is still having difficulty communicating with the comfort system, Bluetooth, and other systems. They say. It may take a couple of days to restablish those connections due to the downtime. Seems odd!

Maybe they didn’t charge the battery after replacing and is hoping your driving will charge it enough to make it work again?

You've done the right thing in replacing the battery given it's age so although you still have the issues you can rest assured you've not wasted your money, I would however ensure this "not very knowledgeable" dealership registered this new battery, that can cause all sorts of problems if not done correctly.
I've seen many people posting how their batteries have failed after around the four year mark even when the battery is supposed to last much longer, don't get me wrong, some do go the distance and then some but it's not uncommon, these cars from 04 onwards are all extremely electronically intensive.
Do you have a voltage meter? I'd use that to check the voltages at the terminals under the bonnet first, I'm not certain on the X6 but to give you an idea my E63 must read over 12v with the engine off and lights on (generally it sits at 12.25v) and with the engine running it will read 14.45v. If mine dips below the 12 I'll start to see problems, nothing to stop the car running but it will shut down non essential items similar to what your seeing, a couple of years ago when mine wasn't giving the 14v I had to replace the voltage regulator that sits on the alternator, this too gave similar problems as it wasn't charging the battery properly.

If your not able to do the wrenching yourself it may be time to try and find a good independent specialist rather than your dealership, a dealership is going to get real expensive real fast as they throw parts at it and have you pay for the privilege.

Here's the forum for your X6 they may have dealt with this before and have some idea as to what's going on.

Thanks

Hsurf,

Great insight, greatly appreciated! Now to find a good idependent in the Naples, Florida area. The dealerships,I agree, are hit or miss. The bmw dealership in Naples is so bad I drive 25 minutes to Ft myers to use an alternative. Is there a way to find a reputable independent. Happt Holidays!
