@@ammakayan1747 Anytime 👍

Hi @AsianBlackR3501, sorry, I have no idea why your comment had disappeared. I am not deleting anything. I have just replied to you a few minutes ago. I hope I didn't do anything by mistake. Actually I am glad when someone uses my videos and manages to get the job done easier and simpler. Honestly, while changing the main battery is possible without removing the passenger seat, I have never heard of anyone to change the auxiliary in the same way. OK, now I am very careful and make sure I just Reply to your message :)

@@konradspages7937 No hard feeling buddy. I did it myself and I know it is possible to do it without remove seat or unplug the connectors. I own 2008 & 2012 Mercede r350 and do most DIY myself. Good job on your video.

I agree, it is possible for the main battery. If you want to change the auxiliary as well, then it's getting complicated.

@@konradspages7937 I changed both batteries (Main & Auxiliary batteries) without remove the seat. I have 2008 and 2012 Mercedes R350.

You are welcome, I am glad it was useful to you. I have made another video for the passenger side and I have explained a little more in that one how to replace the bulb, if you are interested. kzbin.info/www/bejne/eIbJaYeXidKlosU

Thank you for your nice comment. I learn a lot from the internet and giving back to the community is the right way to go :)

Yes, you are right. To access the main battery you don't need to remove the passenger seat. However, for the auxiliary one, you have to do that. For me it's a learning process and I like "to have space" when I work. I tend to disassemble more than necessary, but this will help everyone with a better understanding of how the things are put together.

Yes, it makes sense :) The hood is so short and the engine is practically buried half way under the windshield.

Hi @missimani, no, even if the auxiliary is discharged, and the main one is new, you will still be able to drive the car normally. However, at some point, you might get a message on the dashboard to replace the auxiliary. Mine was good to go after 16 years and two main battery changed.

Hi Edwin, actually this is a great idea. I don't think it will apply to me, as we are planning to drive the car to the ground and then get a new one :) But if the next car will have the same challenges, I will take this into consideration!

It keeps all electronics in the car functioning during the start of the engine, or when the level of the main battery drops too much. I don't know if you are Ukrainian or Russian. This is Google Translate: Он поддерживает работоспособность всей электроники автомобиля во время запуска двигателя или при слишком сильном падении уровня заряда основной батареи.

@@konradspages7937 Благодаря! Българин съм ако това има значение

@@user-xq3rc4me1s I just wanted to translate in your language. For me it is impossible to distinguish in writing Ukrainian from russian, (or Bulgarian) :) Просто исках да преведа на вашия език. За мен е невъзможно да различа писмено украински от руски или български :)

You are welcome :). I agree, it could have been done more ergonomically, but I guess they want to force people to go to the dealership and charge them royalty for the service.

Hi Ian, thanks for the comment. To replace the main battery, you can move the seat fully forward but you will need to cut the carpet, which I didn't want to. As for the auxiliary battery, it might be possible to replace it with the seat fully backwards, but I think it would be a major head ache. I find that removing the seat creates plenty of room to work comfortable. Also keep in mind that all R Classes sold in North America are long wheel base. The standard ones I assume are more cramped. Anyways, good luck!

Hi Alawa, the bulb type is in the description: HID D2S. I don't know in which part of the world you are, but on amazon, you can find it here: www.amazon.ca/Philips-Standard-Authentic-Xenon-Headlight/dp/B01317Y612?th=1 Just type HID D2S. In one of my videos, I have shown the new one, in the box, and out of the box. You can have a look and make sure you buy the right one. Good Luck! PS By the way, if you have access to the bulb, take it out and see exactly how it looks like and compare it with what you can find on internet.

That's right. I'll try it next time. Hopefully it will not complicate everything :) Thanks for the tip!

You are welcome & thanks for watching :)

If you change only the main battery, there is a way to push the seat forward to the max and then roll the carpet behind it, to access it under the floor. If you need to change the auxiliary, you are doomed, the seat has to come out.

Hi @SlightlyDank, you can try to slide one or two pieces of sheet metal band (2-3mm thick) under the clamp and extend it to catch the lip of the battery. I am sorry, I don't know how to explain better.

My pleasure. Anytime 🤠

Anytime!

Anytime.

These are the best comments and make me really glad that my hard, painful :) work was useful to someone else and saved time.

Yes, they are. But they are not perfect :)

I called a mechanic to change the battery, and we didn't remove the seat, just put it as far forward as possible. Done. Then I started the car thinking I wouldn't see the battery warning anymore: Wrong. Instead of the red battery picture, I got a white battery picture, and found out that my auxiliary (I didn't know I had one) was gone as well. No big deal. A new one costs about $ 60. Then I went to find out where the little battery was located, and found out I had to dismantle the car to replace it. It is under the front passenger feet, and to change it I WILL have to remove the front passenger seat, the door sill, the carpet, and the wall lining (so that I can remove the carpet).

@@ronpinto9588 Hi Ron, yes, you are right. The main battery can be changed by pushing the front seat maximum forward. But for me, it was time to swap the auxiliary battery as well, hence the headache :). Honestly, it is not a difficult replacement, but it is long and cumbersome. I am sure, with a little bit of thought, this could have been done way better. Just pick a nice day, good music and a beer (or a cocktail) and it's actually fun. Fun fact, the dealer quote me $180 CAD and I bought a similar battery from Amazon for $24 CAD.

Best vehicle I’ve ever owned

@@ronpinto9588 don't be so lazy. Its 4 bolts. Are your kids as lazy as their dad ?

@@ronpinto9588Do you also step out of the shower to piss? Lazy twit 😮😮

Hi Ron, I can definitely see your point. However, it looks like other people can change the bulbs without taking the headlights out. I did it because my hand just does not fit into that space and I was afraid not to destroy the bulb. But if you have time and have some tools handy, it can be done. I hope newer models are not so complicated. It looks like they are trying to make you go to the dealer :):)

Its actually accpetable. You don't change batteries that often and the whole thing took me 20 minutes.

You are absolutely right. I am not looking forward to the next battery replacement on the R Class :):):)

@Konrad's Pages thanks for making the video by the way. Very helpful 👌 I have to do this job on my r class

@@markfitzy.86 You are welcome. That's why the internet exists, we can help each other. As for the job, take your time, pick a day with nice weather and have fun. If you disconnect the passenger's seat, make sure you have a scanner to reset the error code at the end. No big deal, but you need it.

@@konradspages7937 ok o will. Cheers bro

Hi Almir, I deleted my previous answer by mistake. D2S fits. I have detailed this a bit more in this video, when I changed the other bulb later in autumn. kzbin.info/www/bejne/eIbJaYeXidKlosU

I have chance ds2 ,are right

Are you being sarcastic "brilliant engineering"?

Hi Andre, I don't know if this is applicable for W163. I found that there are slight variations between mirror casings from one model to another, but no big differences. You will know for sure when you take your mirror off.

@@konradspages7937 I will check later today. Thanks again

Hi there! Sorry for the late answer. I am really glad that my video has helped you. This is the best reward for posting on youtube :)

Privet :) That I understood :)

I am so glad that somebody replaced them the easy way :) Way to go!

Hi there, I have another video, for passenger's side where I tried to take the bulb out without disassembling the head light. kzbin.info/www/bejne/eIbJaYeXidKlosU It didn't work (for me), as I have pretty big hands and the space is extremely tight and hard to reach. If you manage to take out the black base of the bulb, you are good to go. Just keep in mind that it would be even harder to put everything back. Be very careful not to touch the bulb with bare hands and not to break the bulb when you put it in. When you put it back, it goes at a very steep angle. Again, on R Class is very cumbersome, and that's why I prefer to take the headlight off and work comfortably on the work bench.

Thank you! I am glad I could help. Yours is the first comment on my first video :)
