Great video, perfect level of detail and description. Thank you!
I had my 330e aux battery changed under warranty at BMW sytner in Harold Wood London, it cost the warranty more than £ 800 !! You saved some dollars there.👍 I do get another 2 years of cover on the parts replaced & I'm jumping into BMW's comprehensive warranty when this current one runs out in June. Just £560 a year.
Thanks man, very helpful vid 👍👊
Thank you so much for this video . Very helpful.
Thank you so much for taking the time to share this. I was plagued with Drivetrain faults and stop/start errors. I also noticed my 12v starter was no longer being used to start the engine, but rather the electric motor. Eventually the problem became worse and I was under the impression my starter system had a fault ($$$). A new Aux battery for around 65$ resolve the issue following your guidance. Car is perfect now. Who knew a small 12v batter could cause so much trouble with no clear error code/warning on iDrive.
Took 1 hour total to change. The hardest part is figuring the bottom left plastic clamp on the battery and the clip on the high voltage connector pushing it back in.
Glad to hear the video helped! Yes the plastic clip on the battery is a bit tricky. Will be posting some more possible issues to lookout for so subscribe and turn the notification bell on not to miss the videos.
Agreed! I had the same experience with mine as soon as I started it afterwards fault deleted itself too! One step to avoid extra headache is I disconnected the HV battery but didn’t disconnect my boot battery which means no need to register! So no need for any obd2
Boss, thanks so much for this video. You saved me so much money and time by doing it myself. All errors now gone.
I did sadly lock my trunk and my back seats don't move, but I managed to jump start it to access it again.
thanks for the support!
Thank you for this detailed video
thanks like and subscribe
Great video, very detailed. Keep up the good work 👍 😀
Glad you liked it!
thank you sir for the information
Worked also for me, didnt go for max edrive and start & stop didnt work so the petrol engine was always on. I didnt have any error codes or warnings from the car. Last night before I changed the battery (190€ in workshop) after driving I got the electrics back like 15mins and after that the car smelled like death, I opened the hood etc and the battery was boiling so I had to tow it in the workshop because they said it could burn 😂
Do you know where to find a replacement positive wire? Can't find it anywhere I've looked. Thanks in advance
***** very helpful
Hey where can I find the six battery to buy? I’m having an hard time finding it in google
Which one good bettry
What error code were you getting with this issue?
This all worked great for me. Had drive train issue and the car was a little jumpy when going from battery to engine. Only issue I found was closing the high voltage switch in the trunk was a bit tricky.
Hi, so after you replaced the battery it became smooth again?? I'm having the same issue!
@@one_quiet_guy4074 when I went to do it I also noticed corrosion on the battery terminals. I sanded them and put grease on them. I replaced the battery also but it could have just been the terminals. So check that before you splash out. I got battery in Halfords with their own brand one. Had to get bmw to remove the error though. (my dad bought a brand new car there so they owed him a favour).
Can you tell me more about clicking the high voltage switch back into place?
@hattrickmac
That was quite frustrating, but figured it out finally.
Hey friend, thank you so much for the video. This is incredibly useful. Could you tell me if it's required to register this battery or is it optional? What app can I use to register it? Thank you!
yes register the battery to ensure it charges correctly
Give thanks .london
Hey man great tutorial, did you have to code it to the car or tell the car it was a new battery?
yes you need to register it
Thanks for the video and detailed info bro really helped me. I don't have the error on the display yet but the error memory keeps getting aged axillary battery so soon it will be off.
no probs bro. glad it helped!
@@TriniVlogs hey my bro need help! I have a drivetrain malfunction msg come up a few times in the space of a few days? Also the stop start mode off keeps coming on? I have to press start button to reactivate this? When switching from electric range when's runs out back to the combustion engine a little tugback and drivetrain malfunction drive moderately msg came up on idrive? Any advice do you think it's worth changing the Auxiliary battery first?
@@mymemories925 get your car scanned to confirm but it may be the auxiliary battery needs replacing
@@mymemories925 sounds like your auxiliary battery is dead
I am seeing the drivetrain fault light on my 330e 2016. Has it got something to do with the auxiliary battery?
yes that could be a sign. you would need to scan it to confirm
When I searched the new battery number that you fitted it says not for stop start, have you had any issue with the battery lasting long term?
yes only last 2-3 years but that's the battery bmw used. may have been a mistake on their part
Im having the same issues on my AH3, inwas able to find a new bmw aux batt, but what are you using to register the new aux batt???
ISTA which is the BMW software
Hello, do you need to register the auxiliary battery (40Ah)? I am about to replace my 2013 Activehybrid 3. I think your the only one that has a video on auxilliary battery and everybody talks about the normal battery (90Ah). Thanks!
yes you can register it as well!
no you dont need to register auxiliary battery...you only need to register normal battery in the trunk
@@arepis1985 ISTA+ has a auxiliary battery register option though?
@@arepis1985 for what is the front battery ? and what charges it ? and for what is the rear battery and what charges it ?
@@benkr5870 front battery is auxiliary battery. its to spin starter motor to start the engine. rear battery is normal 12v battery like other vehicle. both battery are charged by high voltage (hybrid) battery via charging module. No alternator for 330e.
Hi, My car PDC sensors not working and giving Error message- "Sensor- Short Circuit to earth on supply Voltage"
I have also got Error for Auxiliary Battery Ageing needs to be changed"
Do you think the Parking sensors are not working due to the auxiliary Battery?
Thank you.
No. It’s separate issues
My car is a little jumpy when the combustion engine is on and I give it some gas even gently (the car shakes as I press when stationary) I do have aged battery code but could this be the issue or is it something else?
There can be something else causing this issue. You can check your engine mounts for the shaking when stationary.
Because my car has been sitting without being turned on the car doesnt want to start could this fix my car if I change it.
possible your auxiliary battery is dead
I have a 2017 bmw 330E. After the batter installation. Do it have to be recalibration. Or any computer resetting??
Yes the battery needs to be coded in otherwise there will be premature failure of the battery from it being overcharged by the car's charging system. The charging voltage is increased as the battery ages so by coding in a new battery the vehicle then knows to reset the charging voltage to a new battery requirements.
How exactly will I know if my auxiliary battery needed to be replaced ? Took my car for an oil change and they told me I need to replace auxiliary battery & starter battery my car runs good no issues 330e
You can have the auxiliary battery tested with a Multimeter. It's a very simple process. Please do this before changing your Starter because it's usually the auxiliary battery that causes issues.
I have a 2016 330E And they replaced my auxiliary battery about a year ago. I now notice though when I use my electric air pump if I don’t have the ignition switched on it is not as strong. Do you notice the same
havent noticed any issues like that. did they replace it with the same cranking ampeerage?
@@TriniVlogs yes was done by dealership under factory warranty
Nice video, but the battery must be registered with the car,,, in order for the car have this update and to pass the right voltage
Hello, I have a Carly OBD Device. Can I register the aux battery with it?
The front battery is for starting ? And for what is the rear battery ? are they agm batterys or normal batterys ?
I believe the auxiliary battery (in the engine bay) is used as a backup to the starting battery (in the trunk/boot) and assists with the engine start/stop and other systems that require power while the engine is off to put less strain on the main battery and alternator.
@@TriniVlogs The front is used to start the engine and it is used only for that purpose. It is even galvanically separated from other 12V systems of the car. The reason behind it that the frequent starts would pull the voltage of the car so they decided to totally separate.
I keep getting "key fob battery low" changed it 3 times and it's the same. Could this be the issue?
sounds unlikely
What about registering battery..?
Yes battery registration need to be done after battery replacement. I use ISTA to do the registration. You can check a shop to do yours if you don't have a software to do such
Hi the battery does not support start and stop engine is that fine
It would be best to get the correct battery as the regular one may work but will be damaged quickly
Hi thanks for quick reply I really appreciate that what was I trying to say is that the battery you use in video vatara b36 that battery is does not support start and stop is that normal cuz I install same battery and mu car don't go in hybrid mode engine running all the time
I have a problem in my 330e car and i dont know if you can help. The hybrid battery if full and its charging well but the car is not using it. There are no errors but still the car goes on benzin and its not using the electric.
Did you find out was the auxiliary battery the reason for this? My 330e started to make the same thing today like yours.
@@RecreatedI yes this is what they told me from the service. The auxiliary battery must be replaced and a cable also. I have an appointment at the end of the month.
Mine was fixed after new battery, hope yours are as well.
@@KostasKousinovalis do you mind sharing which cable that was. one of the codes for me has a wire voltage overload or overheating....
Hi bro I’m having difficulty finding the correct replacement battery , is there a product number please???
the one we used which comes up with the bmw part number is Varta B36
@@TriniVlogs thank you soo much
Hi bro do I need to register the auxiliary battery after changing it?
@trini vlogs
Yes you should
what OEM battary capacity in trunk on 330e? 90ah?
Yes 90AH battery. Be sure to get the new battery coded in after replacement or else the life of the new battery will be drastically reduced.
I changed the battery, everything well.
But, when i try to switch on the high voltage battery the connect is completly stuck. I put in the screwdriver to unlock and try to push in the red thingy in, and nothing happens. I can push as hard as i want but it seems stuck?? Anyone tips & Tricks to solve this?
Edit: Solved, you need to bend the red clip a little towards the green unit and it slides in without any force or problem. So unlock by simultaneously place the screwdriver at the side and by 'bending' the red slide a little.
p.s. ISTA has a Aux battery exchange registration function! So i guess you should register it.
Hey, which type of battery did you use as replacement. In the video Varta is used but its starting current is 420A and the OEM one is 480A.
I used the VARTA Blue Dynamic B36. it's still running great!@@kardkovacsi
Great video. I have a 330e and this was very informative. Do you guys have email or WhatsApp contact.
