Absolutely fantastic, thank you so much. My aux battery has been dead for a while and I'm only just thinking about doing it. I've ordered the battery and it should arrive in a week and with your help now it will be so much easier - thanks again - LOVE AND RESPECT FROM AUSTRALIA
Worked perfect. I really loved the detailed description of the step by step (even things like moving up the seat, leave driver door open, remove negative battery cable first, etc...[all the tips, hints, and clues, even the socket sizes]) THANK YOU SIR!
Just did this. A telescoping magnet really helped with the nuts and metal plate on the removal and reinstall. Great tip to move the seat all the way back to flip the carpet all the way forward. Easier job than I expected.
My dude I'm by far Not a mechanic BUT THANKS TO YOU I just replaced my battery in my 2007 gl 450...U ARE SOOO SOLID & SPOT ON WITH DIRECTION...THANK YOU! PLEASE show us how to replace the front headlight housing...THANKS AGAIN!!!
Worked great. I had to take a flat head to the old small battery terminal and bend it 180 degrees to clear the cage. Installed the new one facing outside you have (genius). Cleared my 2008 white battery light (without the text for maintenance).
Today you made my day; brown cable was loose, so the battery sign showed up. Only thing I had to do was connect the small brown wire! Now all ok. Thank you for the clear video and greetings from Amsterdam, The Netherlands!
One other thing...How can either the auxiliary battery or main battery be removed if the main battery is dead? Is there a way to move the front passenger seat while unpowered?
You will need to jump start the vehicle and keep it running to move the seat. Once the seat is moved etc. Turn off the vehicle and follow the steps in the video to zero out the car.
*I heard a rumor that in one of those remote tribes' language, the word 'Mercedes' translates to 'needlessly'... & the word 'Benz' translates to 'over-engineered'.* It seems MB has defaulted to the act of (needlessly) 're-creating the wheel'... but evidently, the wheel is now being re-created in the most complicated of ways possible. : ( And it's all in the name of increased 'post sale' profit... and this is continually happening, even in spite of the *HUGE* amount of inconvenience being realized by MANY of their customers in the form of time consuming & expensive repairs. And as a (planned) consequence, the increased costs in labor/parts often times effectively creates a deterrent to budget-conscious owners desiring to perform their own repairs to their beloved MB vehicles. And you can count me as one of those owners. And again, due to the many models of MB cars that require more time, effort & money to fix the now bewildering complexity of often (normally) simple maintenance/repairs found on most other 'standard vehicles' (that aren't branded a Mercedes Benz)... many loyal owners are forced to forgo the DIY process & pay the *premium* prices being commanded for genuine MB parts & labor (performed by MB dealership service departments). It's just ridiculous. I think MB translates quite simply to... The Money Pit. And to be clear, I own a 2001 'money pit'... & I'm finally realizing that... the longer I own it, the more the car reveals (through unavoidable repairs/maintenance) that the overly complex ways in which MB designed & implemented many things... that these particular parts/systems, etc could have (and should have) EASILY been made... well... simpler. What's pretty disheartening to me is that when I was a young lad, I always thought that it would be a great day in my life when I could finally say that I'm a proud owner of a Mercedes Benz. For many years, I thought that to myself. And yes, when that day finally happened about 5 or so years ago, I definitely WAS as proud as I thought I would be. But years later, I've come to realize that way too much money... as well as many (needless) long hours have been spent on keeping my MB in 'top shape'. And again, I blame MB for these 'systemic issues'. And finally, as I end my long & winding rant, I'm realizing that all of this time/money spent has made me much more of a salty/bitter owner toward MB. And honestly, it's made me more sad (as opposed to being mad) than anything else. And I say 'sad' because I honestly feel the 'old Mercedes way of doing business' is not only gone... but I also feel that it's likely gone FOREVER. : ( Sorry for the long rant.
Great video, very informative! Hopefully replacing this on my customers car will rectify the stuck in P, there are a few more faults with the car which may also be associated with this auxiallry battery.
Great Vid. Thumbs Up!....Looks like you should replace both batteries at the same time if they are near end of life. Just FYI, if you are putting back the old "main" battery, you should clean all the acid residue off - soap and water. You can see light acid film on the top of the battery. Believe it or not, that can cause a drain on the battery because it is a "short". It will shorten the life of the battery. It is small, but over time it is a battery killer. You can also see a small amount of rust on your battery tray from acid leaks.......neutralize and clean. If you have time reseal with paint or rust sealant such as Loctite Extend Rust Neutralizer, 1381192. Using an "Acid Neutralizing" Battery Mat is helpful as well to preventing the rust from happening by adsorbing the acid. You can find them on Amazon. They are harder find in the larger sizes for the big batteries used by a lot of the luxury vehicles.
Not sure if you monitor these comments as I know you have a lot of helpful videos going on but my GL320's battery goes flat if I leave it in the garage for more than a week. is this normal? PS. Just found out that my rear power outlet is hard wired in as it has a rear dash cam that monitors 24/7..........would this be the problem? Thanks again and more LOVE AND RESPECT FROM AUSTRALIA
Hi great video, I’m interested in rear parking lamp , one is working the other is not and I checked all the bulbs and they are all good. I have a Mercedes Benz R350L 2006. How would I go about getting the lamp to work again?
You are by far the most thorough repair guy on UA-cam :) I had white battery icon for a while (about 4 months, barely drive car (maybe once a week). Had trouble starting my car one time…. Turned over, wouldn’t start. I let it sit for about 15 mins then started. Just a few days ago, car wouldn’t start. Turned over, but no start. Wouldn’t start with a jump either. Eventually, when I turned key it just clicked. Auto guy says my battery is now dead. However when we have the jumper cables on, it turns over (no start)…. Hope that made sense. Anyway-ANY idea what it might me? Could Aux Battery cause a no start? I never got a Red Battery warning light. Is my alternator bad? Just had starter replaced 5 months ago. Im so confused. (I have both new main and aux battery) … want to replace these before I get it towed but I’d like to know your opinion.
This happened to me too, no point in getting it towed if this happens. You may have to replace the main battery, but you definitely have to replace the auxiliary battery, and you have to remove the main battery to change the auxiliary batter, so it’s easy to do them both at the same time. I know it’s been a while and surely it’s been fixed, but just know next time you get the white battery symbol to replace the auxiliary before the main battery gets damaged again.
Fantastic thank. But I need to change the auxiliary battery on my R Class and it's right under the driver's foot and next to the main battery under the seat
Very informational . I just ordered an auxillary battery for my 2006 ml500 and i will try and install myself using this video. Meanwhile, how do you tilt the steering on the 2006 ml 500? Never did since i bought it 8 yrs ago. is it electronic? If manual, am i missing something?
Hi Sir always enjoy your videos i have an issue with my 2007 ML350, I am seeing the following message on the dash in red " Drive to workshop without changing gears " any ideas what going on with my vehicle your help is greatly appreciated
Your transmission is experiencing some sort of failure. It could be in limp mode as well. This is a safety mode that prevents the transmission from shifting into different gears in an attempt to prevent further damage and get you home. Have it checked immediately.
Thanks bro for you top videos . Did you ever faced an ML320 w164 empty battry after 5 - 6 hours and diagnostic check didn't connect ? We tried all normal ways ... new battery , alternator ....
Good job, nice video, it sounded like I could hear your power steering pump going out in the back ground, you might want to check your fluid level on that. I gave you a thumbs up on this one.
I appreciate the comments and the thumbs up. The power steering pump is noisy - fluids are good. (Probably will change it out before it dies). That's a good observation!
Question is if you disconnect your main battery to chance auxiliary battery do you lose any save memory on you audio or navigation or any other equipment or do we have any other problem on any electronic device.
Great Video , Should be same location for 2010 ml 350?? I have done my main battery twice and never noticed the small auxiliary battery which I'm going to change since it's 11 Years old..Thanks JJ
Great video. Thanks. For 2009 GL320 diesel, getting an error when trying to start (it will not start) that says something to the effect of vehicle not in park, in red letters. Then says "Don't forget your key!" Wondering if low battery in key fob can cause no start, or if it's the small battery - or both. It did this before and would not let me shift gears. I discon battery for 20-20 minutes, it started normally. But all this fun weirdness seemed to occur right after I hooked up a cheap scanner to the OBD2 and tried to erase CEL codes. Immediately thereafter the car would not start and displayed the same or similar messages. What do you think?
First of all, you have very helpful videos! 🙂 Can the auxiliary battery cause the radio/back-up camera display not to come on? I have a 2014 ML350 4Matic and all the fuses associated with the radio are good. I am not getting any sound or display at all. I also disconnected and reconnected the main battery, but it's still not working. PLEASE HELP!!!
Great video thank you. I have a Mercedes ml350 2008. I need to change both batteries like you showed. Your saying I don’t need an external power source or anything to save the on board systems when I unhook the battery if the key is off and the door is open right?
Thank you. Your video was a great help and I changed the battery as you showed. I’m still having a problem with it not wanting to shift into higher gears. I can drive about 30 mph. Would you have any ideas? Also could you recommend a good code scanner tool? I have a 2008 Mercedes ml350 all wheel drive. I’m newly subscribed to you channel and I love it. Thanks
It sounds like your vehicle's transmission might be in limp mode. I recommend the icarsoft scanners. They are brand specific and available for the Mercedes. Low voltages and dead batteries have a way of messing with these transmissions. You may need to do a transmission reset . I have a video on that.
I have a 2013 ML 350. I purchased a new aux battery. Why not just recharge the battery instead of replacing? Can i recharge the aux battery with a smart charger? Or is it better to replace instead of recharge? Thanks
Nice video.... I had this same white battery sign on my dash board and my radio is talking out. I guess it’s cause of the battery. I changed it and the battery sign is still on the dash board. Could there be something else causing the white battery sign to remain on the dash board?
I have a mercedes ml300 2009 make. Was sitting unused for a while at mercedes garage. They tell me they replaced main battery but when I eventually picked it up the auxiliary battery warning came up. After an hour or so drive ABS,EBV,ESP unavailable showed on dash. I parked it and tried to drive it the other day but has difficulty in changing gears I think it's in a limp mode. Does changing both batteries help me?
This video is extremely helpful. Thanks a lot. But I have a problem with my sound system which is exactly like this very one on your vehicle. The issue is, I can't connect my phone because it keeps saying "Phone Not Available". I have tried everything but nothing works. It seems Bluetooth facility didn't come with the sound system. Any other ideas? Thanks.
Hi! I'm having the same issue thanks to your video I notice where it was located the battery, I test the battery out the little out and it said 12v could it be that the battery even though it said that it's still have the voltage,do I need to change it or check other part?
Hi i i have a 2008 meecedes E350 AMG I have a battery warning light on the dash, my regular battery is brand new and my alternator is good, i was looking for the auxiliar battery buth i cant find it any idea where it could be thanks in advance
How long would the auxiliary battery last on an avg? Is it ok to replace it with OEM Duracell 1.3ah 12v? Do you change the main and auxiliary battery at the same time to be safe?
Thank you very much. I have a question 🙋🏻♂️: my ac in my ml350 it’s not cooling wheel , a test to see if it needs gas, but the ac gas it’s fine . . I have to replace the auxiliary batterie because is bad. And also the radiator is leaking very little . Do you know if one of this reasons maybe the problem with the AC??? What I Should do?? Thanks
I have a 2011 ML350, this video is dead on for the battery change, works for main battery also. Also did not lose the codes, per the instructions. HOWEVER if you are changing the Auxiliary battery for the first time, the bracket that maintains the auxiliary battery has to be removed and that is a pain in the arse. The tab only works if you have reversed the battery position so the leads are toward the inside the vehicle rather than toward the outside.
Mi amigo. Muchas gracias por sus vide😊os 🤗😊🇵🇷. Cuando reemplazo la Vateria de 12 voltios. Me sucedió que la batería la habían montado con los polos o cables hacia adentro. Me dio un trabajo! Pues no podía ver. Utilice un espejo para poder ver y desconectar.
Hi 👋,,, I'm having issues with my 2001 mercedes slk 320 electrical system.... Latest issue is the screen wash pump won't work , I've checked pump is ok ,, question is , is there a relay for it anywhere or anything else that would stop it working 🤔 , eg the k40 board ..... any help would be much appreciated 🙏 👍
Both don't have to be changed at the same time. I suggest changing the auxiliary when changing the main battery, but not necessarily the the other way around.
You said something about electronic status zero before changing the battery. So basically take out the push button start as well, AC off and keep the driver side door open? Where do I see the status as zero?
Is this where you would find the aux battery for a c320 as well? battery light came on replaced big battery and then a few days later the light came back on so maybe the aux battery needs to be changed?
Would the auxiliary battery stop car starting I've got. Mercedes a class In it wont turn over I've powered starter up a. It runs (Pulled off cap of relay) But won't start unless u power up the. Igniter wire I checked wires on relay 12v on one positive main wire 3volts on live that powers switch for relay I'm assuming the battery powers up Sam units an alike So stopping it starting Will test will meter tomorro
Great video! I've got a 2015 c300. any idea where I can locate my auxiliary battery? I've heard its in the trunk several times but I've removed all carpets there and still can't seem to figure out where it is. Thanks in advance
Great video thanks. Does the nex battery need to be charged beforehand or does it come charged? Also is this the same battery as needed for a ML 320 CDI? Thanks
I’ve had thesame issue just changed the Auxiliary battery the message is gone but one issue my radio on screen display is not coming on. Could you please help?
Thanks for your response. Ok then, I recently changed the battery and all the preset were still operational,for example, all the windows and the moonroof opening up when holding the unlock button on the fob keypad for a few seconds. That did not change. I did look for one but did not find one.
Hello sir I have a problem with my mercedes ml 320....its stiil blockbustere the navigatioon...it goes but I can not go to orders only from the steering wheel...the auxiliary battery is not changed...it may be from the battery????
Hey brother, great lesson. My brother got a used 2009 ML320 today and we towed home. It did start at first with a boost and we let it run for about 45 min and I did noticed it's saying "Auxiliary Battery needs repair" I wasn't sure what that mean. Now I turned off and try boosting it up forever but it will not start at all. Plus I have the window down and I can't put it up. So, how can I move the passenger seat forward and backward? Please help me out. Thanks.
Sounds like the main battery is totally dead. I would jump start the vehicle and move the seat as needed to gain access. If the main battery is dying/dead it will also trigger the Auxiliary Battery needs repair as well. You need to take care of the main battery issue and while you're in there might as well change the auxiliary one too. Good luck!
Thanks Bro, Yes I did jump started again and it worked now. But I think I am just going to change the Auxiliary Battery for now and will see. Thanks again.
Hi, I notice my c320 2001 the battery dies still even I replace the alternator and the battery; but still getting the visit workshop is this the main cause of the problem?
I have been searching your channel and others looking for help to diagnose my 2005 E500 4Matic Cruise Control issue. My problem is that at exactly 50 MPH or higher, cruise will not engage, below that speed it works fine which is terrible because anything below 55 or more is often stop and go traffic. I am reluctant to think it is a speed, abs or other sensor because it works up to 49 MPH. Once I try to accelerate using the Cruise stem and reach the magic 50 MPH it shuts off. Any thoughts are welcome. The Curmudgeon Man.
Will it make sense to try to bring the old aux battery back to life? It currently has a little over 5V. It was the factory battery that’s been in the car for 6 years. Thanks
@@iRepairAutosI already replaced it with the new one. I was just wondering if I can recharge the old one or I should just recycle it since it’s been in the car for 6 years. Thx
Great video!! I see you use original Mercedes part. I found Aux batteries that fit my LM350, one has a 12v 7AH number. Does this matter at all? Thanks again!
Hello, i have a 2012 GL450 with keyless start, should i be concerned with the system loosing memory as well. Should i try the all systems off and the door open method?
I broke my shifter while car was in drive than I park the car and it went back to park and now can't shift into D or Reverse. Anything I need to do or reset? Thanks!!
I have watched several videos on this subject but none answer the question for my 2015 C-250. Does anyone know where the auxiliary battery is in this model?
This was great! I ended up changing the auxillary and regular battery at that. But now I get a red battery symbol popping up every now and then any suggestions??????
I'm glad you got that figured out. The battery indicator "RED" comes on as the battery starts to die because your alternator was either dying or dead. Good catch!
Hello, Red battery light and red BREAK light comes on episodicly on dash cluster. Alternator and main battery has been replaced. Could this be a aux battery problem? PLEASE HELP ME!!! I have 07 ML 500
No. The aux battery warning is a white light. For the Break light check your brake pad wear sensors, I have a video here ua-cam.com/video/BbJWCBbJMig/v-deo.html about that. Also check your brake fluid level. Your battery and alternator connections may need looking at. Also check the pully/belt that is connected to your alternator.
I've got a w211 2003 e500 I'm replacing the main battery.. will the auxillary battery keep power to the electronics/computer while I'm changing out the main battery?
Great question! No - the auxiliary battery is for the gear selector and the brake assist. You can avoid losing all your settings by making sure all of your components are zeroed out (completely) off. See the video above on how to do it. You can also connect a settings saver (plugs into your cigarette lighter) but I'm not a big fan of those....
No the auxillary battery is for the braking system and gear selection if the main battery is dead. I show how to keep all your settings by zeroing out the mercedes in this video. Please look at the video Thanks.
Absolutely fantastic, thank you so much. My aux battery has been dead for a while and I'm only just thinking about doing it. I've ordered the battery and it should arrive in a week and with your help now it will be so much easier - thanks again - LOVE AND RESPECT FROM AUSTRALIA

Followed your video and was easy to do. Without your video I would never have been able to figure it out. Thanks!
Glad you were able to do this!
Is the carpet all ready cut under the seat for easier access . Great Video

Great Video! And never knew about the battery breather tube so important to let poisonous gases from battery escape out of the vehicle. THANKS!!!!
Thank you for your excellent video.
While I won't be doing the repairs myself, it gives me a better understanding of what is going on.
Glad the video is keeping you in the know. Mechanics can't pull anything on you when doing this job.
It,s excellent and very helpful.
Thank you for helping others with an excellent video 🙌🏻
Great video. I will do this tomorrow. Thanks a lot
Best video on battery changing I have seen!! One question: can I use a trickle charger on battery-using engine compartment posts-? Thank you,

Very thorough video. Appreciated. Last person to change my battery, left off the battery protection cover and vent cover and they cant find either.
Thanks! Sorry to hear that those parts are missing. You can find them at the dealership and or some of those auction sites. Good luck.
Thanks very well explained good job done 🤙

I have a 2014 ML350 4Matic and all the fuses associated with the radio are good. I am not getting any sound or display at all. I also disconnected and reconnected the main battery, but it's still not working. PLEASE HELP!!!
Muchas gracias por el video, tengo un problema no puedo desplazar del todo mi asiento del copiloto automatico...por que es? Gracias
Keith, you da man!
Great video thank you. I have a Mercedes ml350 2008. I need to change both batteries like you showed. Your saying I don’t need an external power source or anything to save the on board systems when I unhook the battery if the key is off and the door is open right?
That is correct.
Thank you. Your video was a great help and I changed the battery as you showed. I’m still having a problem with it not wanting to shift into higher gears. I can drive about 30 mph. Would you have any ideas? Also could you recommend a good code scanner tool? I have a 2008 Mercedes ml350 all wheel drive. I’m newly subscribed to you channel and I love it. Thanks
It sounds like your vehicle's transmission might be in limp mode. I recommend the icarsoft scanners. They are brand specific and available for the Mercedes. Low voltages and dead batteries have a way of messing with these transmissions. You may need to do a transmission reset . I have a video on that.
I have a 2013 ML 350. I purchased a new aux battery. Why not just recharge the battery instead of replacing? Can i recharge the aux battery with a smart charger? Or is it better to replace instead of recharge? Thanks
The car charges it... however the aux battery only has so much life in it and eventually doesn't hold the charge. Replacing is the only option.
@@iRepairAutos thanks brother
Nice video.... I had this same white battery sign on my dash board and my radio is talking out. I guess it’s cause of the battery. I changed it and the battery sign is still on the dash board. Could there be something else causing the white battery sign to remain on the dash board?
I have a mercedes ml300 2009 make. Was sitting unused for a while at mercedes garage. They tell me they replaced main battery but when I eventually picked it up the auxiliary battery warning came up. After an hour or so drive ABS,EBV,ESP unavailable showed on dash. I parked it and tried to drive it the other day but has difficulty in changing gears I think it's in a limp mode. Does changing both batteries help me?
This video is extremely helpful. Thanks a lot. But I have a problem with my sound system which is exactly like this very one on your vehicle. The issue is, I can't connect my phone because it keeps saying "Phone Not Available". I have tried everything but nothing works. It seems Bluetooth facility didn't come with the sound system. Any other ideas? Thanks.
Please teach me how to replace the auxiliarybatteryon my 2020 Mercedes GLB 250 ,thank you
Such a detailed and fantastic video! Thank you for this.
Thanks! Glad it's helping.
Outstanding job!!
Hi! I'm having the same issue thanks to your video I notice where it was located the battery, I test the battery out the little out and it said 12v could it be that the battery even though it said that it's still have the voltage,do I need to change it or check other part?
amazing info? the right information and to the point. awesome
Hi i i have a 2008 meecedes E350 AMG I have a battery warning light on the dash, my regular battery is brand new and my alternator is good, i was looking for the auxiliar battery buth i cant find it any idea where it could be thanks in advance
How long would the auxiliary battery last on an avg? Is it ok to replace it with OEM Duracell 1.3ah 12v? Do you change the main and auxiliary battery at the same time to be safe?
Thank you very much. I have a question 🙋🏻♂️: my ac in my ml350 it’s not cooling wheel , a test to see if it needs gas, but the ac gas it’s fine . . I have to replace the auxiliary batterie because is bad. And also the radiator is leaking very little . Do you know if one of this reasons maybe the problem with the AC??? What I Should do?? Thanks
I have a 2012 ML 63. I found the battery in right rear fender. I can't get the battery out of the holder after taking out all the nuts. Any ideas?
I have a 2011 ML350, this video is dead on for the battery change, works for main battery also. Also did not lose the codes, per the instructions. HOWEVER if you are changing the Auxiliary battery for the first time, the bracket that maintains the auxiliary battery has to be removed and that is a pain in the arse. The tab only works if you have reversed the battery position so the leads are toward the inside the vehicle rather than toward the outside.
Mi amigo. Muchas gracias por sus vide😊os 🤗😊🇵🇷. Cuando reemplazo la Vateria de 12 voltios. Me sucedió que la batería la habían montado con los polos o cables hacia adentro. Me dio un trabajo! Pues no podía ver. Utilice un espejo para poder ver y desconectar.
Thank You !
Hi 👋,,, I'm having issues with my 2001 mercedes slk 320 electrical system....
Latest issue is the screen wash pump won't work , I've checked pump is ok ,, question is , is there a relay for it anywhere or anything else that would stop it working 🤔 , eg the k40 board ..... any help would be much appreciated 🙏 👍
This was a very well done and informative video. Do both batteries have to be replaced at the same time, or can you only replace one at a time?
Both don't have to be changed at the same time. I suggest changing the auxiliary when changing the main battery, but not necessarily the the other way around.
You said something about electronic status zero before changing the battery. So basically take out the push button start as well, AC off and keep the driver side door open? Where do I see the status as zero?
can you pls tell me the part number for the vent port that is locate above the main betterie ! Thx
Is this where you would find the aux battery for a c320 as well? battery light came on replaced big battery and then a few days later the light came back on so maybe the aux battery needs to be changed?
Would it be the same process for jump start or recharge the main battery of a 2008 diesel ml320 Mercedes?
Would the auxiliary battery stop car starting
I've got.
Mercedes a class
In it wont turn over
I've powered starter up a. It runs
(Pulled off cap of relay)
But won't start unless u power up the. Igniter wire
I checked wires on relay
12v on one positive main wire
3volts on live that powers switch for relay
I'm assuming the battery powers up Sam units an alike
So stopping it starting
Will test will meter tomorro
Great video! I've got a 2015 c300. any idea where I can locate my auxiliary battery? I've heard its in the trunk several times but I've removed all carpets there and still can't seem to figure out where it is. Thanks in advance
check at the driver side dashboard on the side
If the back up battery is removed at that point in time does it affect the car memory?
Great video thanks. Does the nex battery need to be charged beforehand or does it come charged? Also is this the same battery as needed for a ML 320 CDI? Thanks
+AusTexish battery comes charged. Same battery for ml 320 cdi, you can also check with the parts dept at Mercedes. They will tel you that for free.
Thanks, this was great and instruction video was perfect. Replaced this yesterday and all came out well. Thanks
+AusTexish glad the video helped you. That's for the feedback.
I’ve had thesame issue just changed the Auxiliary battery the message is gone but one issue my radio on screen display is not coming on. Could you please help?
Thanks for your response. Ok then, I recently changed the battery and all the preset were still operational,for example, all the windows and the moonroof opening up when holding the unlock button on the fob keypad for a few seconds. That did not change. I did look for one but did not find one.
Can you show this procedure where the auxillary battery is inside the cabin, under the glove compartment, like on Mercedes GLA 250?
Hello sir
I have a problem with my mercedes ml 320....its stiil blockbustere the navigatioon...it goes but I can not go to orders only from the steering wheel...the auxiliary battery is not changed...it may be from the battery????
do you have to reset anything when replace aux battery
Hey brother, great lesson. My brother got a used 2009 ML320 today and we towed home. It did start at first with a boost and we let it run for about 45 min and I did noticed it's saying "Auxiliary Battery needs repair" I wasn't sure what that mean. Now I turned off and try boosting it up forever but it will not start at all. Plus I have the window down and I can't put it up. So, how can I move the passenger seat forward and backward? Please help me out. Thanks.
Sounds like the main battery is totally dead. I would jump start the vehicle and move the seat as needed to gain access. If the main battery is dying/dead it will also trigger the Auxiliary Battery needs repair as well. You need to take care of the main battery issue and while you're in there might as well change the auxiliary one too. Good luck!
Thanks Bro, Yes I did jump started again and it worked now. But I think I am just going to change the Auxiliary Battery for now and will see. Thanks again.
What year is this? I have 2010 where would the auxiliary battery be located?
Thanks for tell me what the aux battery is for.
Hi, I notice my c320 2001 the battery dies still even I replace the alternator and the battery; but still getting the visit workshop is this the main cause of the problem?
Is the axillary battery in the same location for gl 450 2007
Thanks for the video now I can fix my wife’s suv 🦾🔥
What is that computer beside that battery?
I have been searching your channel and others looking for help to diagnose my 2005 E500 4Matic Cruise Control issue. My problem is that at exactly 50 MPH or higher, cruise will not engage, below that speed it works fine which is terrible because anything below 55 or more is often stop and go traffic. I am reluctant to think it is a speed, abs or other sensor because it works up to 49 MPH. Once I try to accelerate using the Cruise stem and reach the magic 50 MPH it shuts off. Any thoughts are welcome. The Curmudgeon Man.
Hmmmm. Do you have an icarsoft scanner. It will tell us exactly what dtc error codes your cruise control system is throwing.
Would this be the same general procedure for a 2014 Mercedes S550?
Yes. Aux battery may or may not be in the same location.
iRepair Autos I did this changed the battery but it’s still not shifting
hello, I changed the auxiliary battery and main battery on my 2013 s550 and still got the same symbol. Any ideas or suggestions?
Please can you tell me where is Auxiliary battery located in a Mercedes E220 Blutec 2015 Model
Mi auto ml 350 2011 me salió código de mal funcionamiento batería auxiliar. Si la cambio resuelvo el problema?
Will it make sense to try to bring the old aux battery back to life? It currently has a little over 5V. It was the factory battery that’s been in the car for 6 years. Thanks
I would replace it. Especially if you're replacing the main battery. It's too much of a pain to put off replacing it.
@@iRepairAutosI already replaced it with the new one. I was just wondering if I can recharge the old one or I should just recycle it since it’s been in the car for 6 years. Thx
Great video!! I see you use original Mercedes part. I found Aux batteries that fit my LM350, one has a 12v 7AH number. Does this matter at all? Thanks again!
I try to use original OEM when at all possible. How much of a difference in price is the after market one?
Half price. But I also want to make sure that the AH numbers matter.
Here's what matters: physical size, voltage, and amps; the OEM is made with non spill fiberglass.
Thanks! Top-notch video, thx again! Can you make one on how to change the window switch, driver's side?
Hello, i have a 2012 GL450 with keyless start, should i be concerned with the system loosing memory as well. Should i try the all systems off and the door open method?
You should zero out the car to avoid losing memory settings etc.
Hi to help I have Mercedes Benz C LA 250. And is not starting And every time I put the keys All the light I hope you can help me Thank you
Is it cranking?
I broke my shifter while car was in drive than I park the car and it went back to park and now can't shift into D or Reverse. Anything I need to do or reset? Thanks!!
I have watched several videos on this subject but none answer the question for my 2015 C-250. Does anyone know where the auxiliary battery is in this model?
This was great! I ended up changing the auxillary and regular battery at that. But now I get a red battery symbol popping up every now and then any suggestions??????
Hi Tania, What's the year make and model on your vehicle?
Hi it's a 2010 ML350 but I figured it out....its the alternator
I'm glad you got that figured out. The battery indicator "RED" comes on as the battery starts to die because your alternator was either dying or dead. Good catch!
Hello,
Red battery light and red BREAK light comes on episodicly on dash cluster. Alternator and main battery has been replaced. Could this be a aux battery problem? PLEASE HELP ME!!! I have 07 ML 500
No. The aux battery warning is a white light. For the Break light check your brake pad wear sensors, I have a video here ua-cam.com/video/BbJWCBbJMig/v-deo.html about that. Also check your brake fluid level. Your battery and alternator connections may need looking at. Also check the pully/belt that is connected to your alternator.
hi brother from zimbabwe well done
Thank you.
I've got a w211 2003 e500 I'm replacing the main battery.. will the auxillary battery keep power to the electronics/computer while I'm changing out the main battery?
Great question! No - the auxiliary battery is for the gear selector and the brake assist. You can avoid losing all your settings by making sure all of your components are zeroed out (completely) off. See the video above on how to do it. You can also connect a settings saver (plugs into your cigarette lighter) but I'm not a big fan of those....
No the auxillary battery is for the braking system and gear selection if the main battery is dead. I show how to keep all your settings by zeroing out the mercedes in this video. Please look at the video Thanks.
Hello, can you help with location of 2014 mercedes sl auxiliary battery?!
Very helpful thanks
isn't there also an aux battery in the back fuse box?
