Replacing complete BSD module is way faster than replacing only carbon brushes, also you need to have some tools and knowledge for soldering. Moreover, in some cases issue can be in BSD module itself, not in carbon brushes. But on the other hand, brushes cost me 1 Euro + some time for replacement, complete BSD module is 50-70 Euro.. So it is your choice.
What about 4A07 alternator communication error ? This is showing me after alternator repair, before the communication was ok but sometimes the alternator didn't charge the battery so the car was stopping,now the car doesn't stop but the communication between alternator and computer is lost

If you have some communication errors then I believe you need to replace complete BSD module. Carbon brushes replacement only helps to restore electrical contact to the rotor. Or just make sure you put all the screws and connectors correctly.
@ The module was replaced but it think is not the right one , i found on the forum that if the alternator doesn't have the same Ampere output will cause this error , so probably my regulator is for 163hp an not for 177hp e60 that i have , this the only solution to replace it again,someone at the service miss replaced the right part ....
So what kind of codes did you get did u the 2c7e BSD Malfunction

Hi, I don’t remember having any error codes just low battery warning very often. Thing is that charging voltage was not stable, when I rev car voltage suddenly drops to nearly 12V. It should be stable all the time ~14V (for diesel engines).
Never change voltage regulator! Only original Valeo if new or change the brushess like in a video. This type of alternator is controlled by main computer (ECU) via COM signal (BSS), oil sensor also communicate via BSS. So in this case, if any off those two parts aren't original it can interrupt signal and make others system work improperly

Sweet video...but that sound track makes me want to break something.

Yes you fixed it probably but isn’t over voltage after fixing 14.70
I think its kind a high for your car !!

after changing a new one with heatsink got oil sensor fault and im a bit confuse at this point
Did u sort out the oil sensor issue?

14.7 v is perfect for running car.
