Correct - all that may be reported is low voltage output from the alt.
Thank you for your presence and participating in solving this issue. yeah, some of these codes will change depends on the battery State of charge, but they don't pinpoint where are Exactly the issue. I have experienced that since last year when I had the issue with the voltage regulator. As I said before, I had a strong possibility that the problem lies in the alternator, but I did not want to exclude any of the other components due to the large number of them in the charging systems on this vehicle and because it's the most expensive and most difficult part to replace on the charging system, especially in the E500 class, as there is not enough space So a lot of things should be removed like the metal plate on top of the radiator the fan shroud and all the radiator lines on the front passenger side plus loosing the engine coolant. Imagine that you are doing all that and the alternator was not the problem. This means that you will do the same procedure twice. That is why I did not rush the matter and replace it, although I've had tested it and the result was negative, but I should have made sure that all other elements on the charging system are intact, and after confirming that, I did removed it . I even took it to autozone to test it so I can be a $ 100% sure that it is defective, And it really was. And now with all confidence I will put a new alternator

And to state it again, make sure the batteries are fully charged before starting the engine with the new alt. Good luck.
sorry to bother you again bro, I was at mercedes-benz site shopping for the alternator but I don't see no new alternators only remanufactured. I thought of buying it from the dealer so I can ensure that I'm getting the genuine part but new not remanufactured otherwise I were take my old one to the the alternator repairs shop and fix it for less than a $100, what do you think ?

If you provide me your VIN I will look through the MB parts catalog and see what I can find. I will also look through the Bosch parts catalog to try and confirm the cross over of part numbers. Bosch is the OEM and installing the correct alt is important. Some of the aftermarket units are 'one size fits all' kind of application so you have to be careful.
Sorry, I didn't see the screen shot you had attached. The FCP part is not a cross over based on the item for the 014-154-01-02-83 (the 83 at the end donates it is a reman unit, the core charge also confirms it too). Get me your VIN and we can go from there.

The link from FCP I sent was not a reman. They offer one, but it is half the price compared to the link I posted. It fits a W211 E55.

Ok, your info was correct. The original alt part number for your car was 013 154 82 02 which was superceded to 014 154 01 02. You can purchase from MB but you may wnat to buy from an online dealer that offers a discount such as this dealer that offers about 30% off: https://parts.mbofcovington.com/oem-...Y4LWdhcw%3D%3D
Alternatively, the Bosch cross over to this alt is AL0789N which you can spend $253 from: https://www.rockauto.com/en/moreinfo...=2412&jsn=1055
RockAuto also have the Bosch reman of that alt for about $30 less than the new price. Good luck

thanks for the links, wow it's a big difference in price, I usually buy my parts from FCP euro And I always thought that their prices are reasonable compared to the quality and lifetime warranty, they have the remanufactured genuine Mercedes alternator for $503.99 and for bosch alt $295.99 new and $314.99 remanufactured. I wanted to go with the new genuine Mercedes alternator But it looks like they stopped producing it Because yesterday I called the dealer to see how much it costs, and I thought that they only use and sell new parts, and when the salesman told me that the price was $500, I was happy and wanted to make sure that it was new or remanufactured, unfortunately, even them they only have the remanufactured. And I think if it was still being produced, it wouldn't be less than $700, so I have to go with only what's available

Yes, MB does have a reman program and many parts come through that. A dead give-away is when there is a core charge when the price is listed. The core price is to assure the old unit comes back so the reman channel stays full with units. And, when the total price includes the core price (such as the FCP prices of $295.99 and $314.99) the core price is deducted from the reman cost as you get that back when you send in your old part. There can be a huge difference in the quality of reman'ed units so you have to be careful. MB units are well done and Bosch likley the same. Finally, the difference in the prices I pointed out helps to show the ultimate cost of the FCP lifetime warranty. In some situations it is worth it and in others maybe not so much - personal choice. i hope this is helpful.

one last opinion I wants to hear . if it's you, which one would you go with? the new bosch alt or the reman genuine Mercedes. I may be giving the topic more than it deserves, but believe me, I was never confused with all the parts that I replaced over the past years, because they were often individual parts or systems, but here the matter is different. The generator is the heart of the car. In addition, the cost here is not easy. Replacing the alternator, engine coolant, Drive Belt & Tensioner and don't forget the labor. so I want to do it once for all
