How To Replace and ADAPT a VW or Audi Battery

[@HumbleMechanic]

Here is the battery code list for different vendors. Im not sure it REALLY matters, but might as well do it as right as possible LOL Battery Vendor List: Varta - VAO Exide - TU3 JCI - JCB JFF Boading - 5D0 Banner - BA2 Sebang - GBC Exide Technologies SA - TU1 JCI Mexico - EMC Unknown - UNK

VW tech here. I really feel like you taught me a lot before I began my career in this industry, however, I do feel the need to correct you on one thing; You do not need to lock the vehicle to allow the bus and sub-bus systems to fall asleep in the battery adaptation process. That is a common misconception among a lot of forum users with battery-monitoring vehicles, and while maybe a good thing to do in practice, is not necessary. Very informative to anybody without the knowledge prior, but it is just an extra step that can be avoided. Still thankful you put this video out, though, because I am getting sick of customers coming in with brand new batteries that died after 6 months due to improper adaptation. Hopefully people begin to learn that battery adaptation is a very real and legitimate part of most vehicles from now until forever, probably.

[@rgolab3174]

So if locking the vehicle to allow the bus and sub-bus systems to fall asleep is not necessary then why it may be a good thing to do in practice?

[@theking965x]

I have a question I replaced my battery like 3 months ago and when I turn the battery on only in the car my obd11 says the battery is discharging would you think it’s too late to do the adaptation or doing it will still prolong the life of the battery?

[@rgolab3174]

@@theking965x I never did adaptations and the car worked fine. I say the whole adaptation thing is a bunch of b.s. I did have a problem once after a new battery install after 6 months but it was a battery problem. It turned out one of the cells died. I exchanged it under a store warranty and the replacement is working fine after 4 years and I didn't adapt it either. I'd thoroughly test the battery and if it's fine then test for parasitic draw. Search youtube if you need to find out how to do that.

@@rgolab3174 It would be good to lock the car so no one goes into the car and prolongs the "waiting to sleep" timing

So, for the adaption would it be binary agm or fleece if battery is an AGM premium battery from either walmart, Autozone or advance autoparts?

[@LUNArXpedition]

Current VW tech here, battery adaptations are needed on vehicles of 2018 and new (at time of writing) or any vehicle that has a negative peg on the firewall right above the battery (best seen at 3:52 with the yellow nut holding it down) Super annoying that I can go from a 2017 Jetta just dropping a new battery in, to a 2023 Jetta needing an extra 30 minutes to connect to our ODIS diagnostics system, sign in to DSS, scan the battery and submit the GFF log.

[@georgecummings7559]

2017 GTI here with manual transmission. It is my understanding that if you don't have the plug in module that is attached to the negative terminal, then there is no need to do battery adaptation. I also thought that another indicator of needing to do adaptation is whether your car has the stop-start function, which is not present in a manual transmission car.

[@kaurvali]

Few important notes on battery type in coding!! There are two options for AGM - Fleece and Binary AGM. Optima or 'performance' batteries are Binary AGM which means AGM spiral wound (usually indicated by the round cells. OE replacements are Fleece aka AGM Flat.

[@MrTheHillfolk]

I've still got a blue top that's kicking from 2007 ,it's in my mk4 project car and it's "good enough" for the shop stuff I'm doing but I'll need a new one when the cars roadworthy. A load test said it's only got like 60% capacity. I'd say that was/is a good run. I put a yellow top in the wife's 2014 Jetta recently, fingers crossed it lasts 10+yrs.(I've heard they ain't what they used to be)

[@deadduck8307]

I've never understood why performance cars use AGM in the engine bay. AGM is just a way of suspending the electrolyte (sulfuric acid + distilled water) in a gel so it stays in contact with the cell plates regardless of how the battery is oriented (flat, on its side, at an angle, etc). But this comes at a performance cost since it's sealed, you should limit how fast it's charged so as to limit hydrolysis (hydrogen gas formation from the splitting of the H20 into Hydrogen and Oxygen). Some of the gas is re-absorbed just like how a shaken Coke bottle won't go flat if you don't open it. But it's in the engine bay which is well ventilated and it stays mounted relatively flat. You'll get better charge performance from a regular non-sealed, non-AGM battery at the cost of topping it off w/ distilled water every couple years and making sure it stays upright. This is just not the right application for AGM from what I can tell....

[@RC-ic1co]

Thanks, that sounds very helpful.

[@deadduck8307]

@Floyd. B I can't comment about the open/wet batteries as I don't know if I've ever seen one in real life... but that sort of lends credence to your claim that they're rare... That said, I've never had a lead acid battery (AGM or not) that I couldn't refill with distilled water w/o using a syringe but I don't mess w/ the cylindrical style AGM -- they seem like a gimmick to me. The non-AGM, regular ol' car batteries have those two plastic caps that plug 3 holes each. Take a flat blade screw driver, pry 'em off, pour distilled water into each of the 6 cells, put plugs back, hit plugs w/ hammer to seal, profit... It's easy enough for me to do a couple times a year. EDIT: In my truck, I have a standard battery from Walmart, just google "EverStart Maxx Lead Acid Automotive Battery, Group Size 24F" ... I also have a small 10w solar panel on the hood of my truck (it looks like a hood-scoop until you get closer and see it's a solar cell). The cell provides 22v open circuit @ 330mA in bright summers day which keeps the battery charged when parked for extended periods. But, 22v will cause gassing (anything over about 14v will), so I add water every now and again. So far, my battery is 5 years old and still going strong.

[@deadduck8307]

@Floyd. B It has a small 100w or so solar charge controller, but lately I've bypassed that in favor of just a diode. The charge controller has 2 LEDs that are always on, and the 40mA parasitic power draw can somewhat defeat the purpose in some situations. Since it's only 10w rated, 6w installed w/ perfect conditions, it should be fine to go w/o the controller, though the controller is there if I wanted to wire it back in. It's interesting to hear that European batteries are sealed to such a degree. If you can't add water, I can't see the batteries there lasting more that 2-3 years especially in a hot engine bay... with proper maintenance, I've seen them go 10+ years.

[@clementadams2055]

Thanks for this video! I just bought a model year 2017 Audi A4. After seeing this I checked the battery and saw that it was original, put in service in 2016 so I knew that battery had to go. After digging it out of the trunk, replacement was easy, and no coding was necessary. I tried putting the positive and negative cables together for 45 seconds to zero out the capacitors? But the car computer memory remained and everything was normal when I restarted the car. You save me a bunch of money! Thanks for the confidence you gave me to do the job!

[@pavelppp888]

Hello, Charles, As an automotive engineer, I can give some details on the “unknown why’s” in the process: - the prerequisite for opening the hood is to ensure that the vehicle is stationary before performing diagnosing procedures like adaptations, which lead to reset of important modules (the gateway is pretty important module and is not supposed to reset while vehicle is in motion) - the waiting for some minutes with vehicle locked is to ensure that all the car’a busses are put to sleep by the gateway. Once they are not active, the gateway goes to sleep as well. Then, on wake up, some of the errors are removed by the gateway. - the rotating of the steering wheel from end to end is also to clean some under voltage errors in the esp/abs modules. - the disable of DoIP communication will be more and more required for various procedures in the newer VW platforms when working with VCDS, at least before RossTech update their products. P.S. The SFD will really hit all of us - the car enthusiasts…

Actually, rotating the steering wheel gives the zero position reading. The encoder is absolute, but only for one rotation - by going lock to lock, it knows which rotation is center. The fault that is causing all those messages is "steering angle offset not learned".

I can't quite believe it but I am just passing 10 years on the factory battery on my A6 TDI. This is even dealing with severely cold winters.

AWESOME!

[@adrianmartinampuero2009]

This is an awesome video, because the information is not available in any source. You deserve way more subscribers man. Just to add a little bit more background: - The serial number is important because it gives the car precise info about the age of the battery. Coding a 1111111112 you are just telling the car that something has changed but he isn't sure about the capacity [Ah] the battery could have lost with its age. - The most similar way to VAG factory to code a battery is to search in your battery sticker the production date of the battery, and code the following serial number (without spaces): Z Y MM DD ZZZZ Z - unimportant numbers, you can insert whatever you want Y - Last digit of the production year (2023=3) MM - Production month DD - Production day If you do this, the car will know exactly when the battery was produced, and you will have coded a battery exactly like a VAG dealership. Love your channel♥️

[@adrianmartinampuero2009]

Addition: Your previous battery showed 1111111111-JCB because it was the first one, and all the VAG cars when they leave the factory get coded the same (as the car is brand new, he doesn't need exact info about the battery to know that it is also brand new, so they code it like this to save production time). However, if you had done this battery change in a Volkswagen dealership, I can assure you they would have code it as I explain in my previous comment, because the alternator needs the exact production date to expand the battery lifespan. I hope this information helps!!!

[@RC-ic1co]

Thanks for your explanations elaborating the idea of storing the serial number. Excuse me, I'd like to understand this even more: So how will a battery be treated differently based on its age? (Also I wondered how VW didn't find it necessary to code the information in production, because the battery is bew - I mean... if you are replacing a battery, you are also putting in a new one. Isn't that the exact same thing? 🤷🏻‍♂️

[@adrianmartinampuero2009]

@@RC-ic1co Hi! Let's see if I can explain myself correctly: The difference between older batteries and start/stop batteries belongs to its charging procedure. Older batteries can be charged by constant current whereas start/stop batteries need an 'adaptive' charging process based on its instant capacity [Ah]. It would be like saying that older batteries could be charged the same way no matter what, and newer batteries needs to be charge one way or another depending on its age. In actual cars (with start/stop) the alternator needs to know the exact 'life status' of the battery, in order to choose the correct charging procedure for it. When your battery is starting to die, (it will be loosing Ah) the alternator will not charge it further than X% simply because the battery will not accept it. Due to this, if you replace the battery but 'you don't tell the alternator' (and with this I mean you don't code the battery) the alternator will still think that you have a battery near to its death, and won't charge it over that X% that I was saying. As you can tell by this point, you will have a battery that DOES accept 100% charge, but the alternator isn't providing it because of the previous battery, damaging its new lifespan. I hope I explain better this time. For the second part, I guess that as is a really particular topic where all the ECU's are completely new, they kind of understand that every piece of the car is also completely new. But, as I said, that only works for the first battery change, for cars that have just left the factory. Is not the usual case.

[@chrishard7616]

@@adrianmartinampuero2009 I didn't realise that constant current was used to charge lead acid batteries. My understanding is they are normally charged by voltage regulation to say 13.8 to 14.2V then battery takes the required current depending on its charge state. Maybe they are now using a combination of constant current to start with then revert to constant voltage.

[@Bond2025]

It would remove the need for any of this providing the battery was the same type. THERE IS NOTHING IN THE BATTERY THAT TALKS TO THE ECU, so the ECU doesn't adjust anything in a dynamic way for charging, or alter charging patterns based on age - that is all rubbish to add extra costs to a simple replacement job.

Might be worth adding a note about the "battery technology", apparently the "Binary - AGM" option isn't correct for standard AGM batteries and the correct method is "Fleece".

You could explain the WHY you should do it. I had to research this. There are different settings, for instance AGM. This setting changes the way the alternator delivers voltage at startup and during charging. Also, when you change adaptation, it signals to the car that a new battery is installed (even if its the same type). You update the software, even with the same replacement battery, because that tells the computer its a new battery and to charge it differently than it would a diminished battery.

The computer adjusts the alternator as the battery diminishes so it is reading in real time what is going on. This is just a scam to help dealers. It's german over engineering

[@leehsterh8616]

Great job on this video. Clear and concise. My question is about the OBDEleven. After I select 19 Gateway, then Adaptation, the menu I see after that is Channel (only). I think I am supposed to guess what channel to enter, which I tried, but I don’t have anything as nice as the menu selections you have. Did you purchase some extra options to get the menu selection choices you have?

Excellent. I wanted to add a set of C-TEK leads on my mk7 GTD and tried to do this without upsetting the battery. Turned out that I couldn't and your video was invaluable to help. Really good step by step guide and it worked. Who knew you cleared the codes by turning the steering wheel (after the earlier steps). Also turned out that the coding was not quite correct for the battery that was installed. Many thanks for your video.

[@NyksWyldMynd]

I checked the battery in my 2014 Jetta TDI last week. Apparently it's from late 2013 but still running strong. Down to 12.4 volts, but not bad for 9 years!

[@EudesRJ]

Have you checked how many CCA it is still delivering? I got a “BM550” battery tester (really cheap) on Aliexpress that works just fine for that, I compared it with the readings from a “professional” equipment on a shop (pretty much the same results/reading)

[@jamesbrown2163]

@@EudesRJ I agree those cheap battery testers are extremely useful in testing batteries. You learn a lot by testing often on a range of batteries. When the battery is dying the internal resistance goes up and the CCA goes down.

This was exactly what I needed. $500 for the dealer to change with an OEM battery. Also, with a small bit of modification to the battery tray, an H7 AGM will fit in a 2021 Tiguan.

[@jbt369]

Is there any reason you can't jumper another battery in parallel with the one you want to replace, then take the terminals off of the old battery, slide in the new one, put the terminals on, and then un-jumper the minder you put in place, the better to not lose all your settings? Would that not work?

[@gmans7859]

Thank You Charles. This step through was most excellent. I too like to put those Terminal Covers back on whenever possible. Trim them etc. I like to put them back on after the removing cable(s). No boo boo's allowed. Also, I have a Label Maker and got into the habit of putting the 'In Service' date on our batteries so no guessing how old they are.

@@seanl7130 I did a 2017 GTI with AGM no adapting, no issues, just drive it, lights all reset. And a 2018 Tiguan, AGM no adaption, just drive steering wheel left right On my 2019 Golf R I went with the original type EFB, just because, i did an adaption, just because, and the aH rating was slightly higher than OEM...does it really matter? probably not, I read elsewhere if you don't adapt to correct values it charges battery differently, who knows . But dealer told me, if stuff works you are good, usually only need adaption if something acts squirrely. I did mine at like 4.3 years on the R...no issues, but that is the time range, anything can all of a sudden happen, when you least expect it, usually raining at night. I had a 2013 tiguan go over 6 years, it did die one day, and i realized, I just forgot all about changing it....one day good, next day dead, which batterys do. Luckily it was home, just went to Auto Zone got a 3 year warranty full replace battery, popen Z in, 2013 did not use any kind of adaption protocols, that battery went only 3.3 years!! to reach 50% of course, right after warranty, which means it was actually well made it lived to it's spec. Changed it to a VW OEM battery at the dealer this time...I have had good luck with lots of Auto Zone batterys over the decades. East Penn Deka(great stuff, i use in motorcycle Deka brand, and in my honda portable generators), Johnson Control, Exide, are the basic makers of em all for U.S. batterys. I see Varta is OEM in factory batterys...

I will now adapt that new battery because my dash panel is a veritable discothèque! I learned so much from your VCDS & Battery video's. Thanks once again... marcel

[@gianseven]

Can you provide 12V to the leads while the battery is out to avoid programming? (if it's the same capacity and technology) This method is sometimes used when replacing cells inside laptops' battery packs that have an electronic "fuse" that blows rendering the pack's circuit useless if it doesn't senses a battery voltage at all times

[@gregordiseth6651]

I just replaced my battery (Interstate from Costco) - and I did hook up 12v to the leads when I disconnected them. Absolutely no error codes, warning lights or window programming needed, my GTI didn't know anything was changed! I haven't done the adaptation, and it's been a few months, no issues. I believe the battery capacity is the same, though.

[@tomhummel2641]

Yes, I answered that in a separate comment right now. If you use another battery for that, it can be a smaller 12V battery. Be aware of sparks due to different potensials/voltages, best to use cables made for charging that will "absorb" a short time spike and connect to ground/body for the minus polarity. VW / Audi Group (VAG) statement: "After replacing the battery it is necessary to adapt the battery to the vehicle. If the adaptation is not completed, the start/stop function will be inoperative. Additionally, charging system operation may be effected and various DTCs can result. "

[@kennethking2301]

Great video and great information. Modern VWs, like my 2018 Tiguan, will set a check engine light long before the battery is too weak to start the car. As long as the battery doesn't have some sudden catastrophic failure, the car will let you know when it needs a new battery.

[@cassoidGaming]

That is correct. I’ve done a couple tiguans inside the delear as a VW tech and it will throw the check engine light on with a whole bunch of faults stored in multiple modules with low voltage everywhere. Sometimes cars come in with aftermarket batteries and they were never adapted so I would perform a battery test to see if it was good then perform battery adaptation on ODIS. VW scan tool if good. If battery weak and failed I’d sell new battery and perform adapt. If it’s on 111111111 and has aftermarket battery. It was never adapted and is factory adaption

[@speedgtr1958]

How reliable is your Tiguan. I am looking to buy new one but is it worth it over getting new Honda CRV or Toyota Rav 4. I dont mind if its a bit more to maintain than Honda or Toyota but I am wondering if they break down often or burn oil there.

@@speedgtr1958 , it has been very good. Mine currently has 91,350 miles and the only problem I encountered was a problem with the injector wiring harness that was fixed under warranty.

Just a note. Advance Auto Parts is able to the battery reset. They started getting the extra module they needed about 6 months ago. So if you are buying a battery from them they can do the proper install. And another note, Die Hard batteries are made by Clarios as well. There are only about three major manufacturers in the US, Clarios who used to be Johnson Controls, East Penn and Excide.

Too keep all the values and avoid all error messages after replacing the battery: Before removing the battery I connect my DEFA Smart charger to the battery cables , put the charger into power mode, i.e. constant voltage 13.6V by keeping the "on"-button pressed until the LEDs display a moving pattern. Very easy and convenient. Battery-adaptation is necessary in Start/Stop-systems like 'Bluetech' in VAG terms.

[@ZainAhmed]

You want the car to completely drain and recharge the battery to avoid 5 mins with a scan tool? Even if it did, the car would not get an accurate measurement of the battery capacity without draining it so low that the computers brown out. Then what? How are you going to start the car to recharge the battery? The only non stupid way to do this would be to add a small memory device to the battery that clips in to the car, and that is just as ridiculous as the original idea. Also even with a drain/refill, how the hell is the car going to know what the battery chemistry is? Just smell the battery? 2 mins with a scan tool is fine.
