I'm assuming you posted this on your phone or something as I understand this less than my 4 year old. That being said, I think you are trying to say you got a code that its not charging? I'm guessing probably the voltage regulator is on its way out.

Go ask on the 100k e63 thread or pm the thread starter. He just changed the voltage regulator and may be able to confirm for you.

Yeah, i replaced my voltage regulator on my 2010 e63. All was good, but then my battery went out, i am imagining because of the stress on the battery while the regulator was bad. I mean it was going from 100amps power, overcharging the battery, letting it bump up to 15v, all the way to PULLING 100amps from the battery, draining it down to the 8's and 9's while driving. I think around 8.7 the car shut off. After the voltage regulator, my amps are still varying while driving, but nothing like before.


There is one more video on my channel if you'd like to check it out.

Car did fine after voltage regulator, but then i noticed when i parked the car, i would turn it off and the battery would be at 12.5. Literally seconds after i turned it off it would drop to 12.0, then 11.9, etc. Replaced battery, it starts up every time, but i will say it still drops to around 12.3 when sitting. 12.5-14.8 when driving

Just get with the dealer, and give them your VIN and they should get you the right voltage regulator. I know there are some different ones so be careful. I almost ordered the wrong one. The dealer got me hooked up with the right one for around $120. Took like 30 minutes to install

Not sure why you would spend almost 3 times the price when it was likely the voltage regulator, but as long as it fixed the problem, thats good.

I was thinking to do the regulator and its was 125. And at the same time I got a good price on the alternator so I was like I change the all thing and I know it's new
