For most newer VAG group cars we have been buying and selling TPS supplied batteries (Varta or Yuasa) with BEM code stickers and coding them via VCDS. Had few hours in VW dealership today to learn - these BEM codes having nothing to do with battery management and more to do with warranty (to prove the battery you are claiming for was actually the battery on the car in question). I have fitted aftermarket good make batteries to VAG group cars - Exide and Bosch with no problems at all - we have always fitted AGM for stop start applications. Done a bit of research - if you put any 11 digit number in - the battery management system will think it has a new battery and if you don't - after 2 to 6hrs of vehicle use it will self learn and will sort itself out. Only thing I can add to the above - you want to buying a battery with the same CCA and AH as the one you have removed. Learn something new every day...

We just use 1111111111 and we swap any EFBs to AGMs and change it to VAO/AGM in the set up page
Newer VAGs we have to select "gateway" to do battery matching

It had for a BEM code for an Exide AGM stop/start battery: 096 TU3 1111111111 096 being the battery size and TU3 being the code for Exide from VCDS drop down menu. I am learning something here about VAG BEM codes - sort of a "little home study cource". Thanks trickydicky...

It might of been AA, we tend to always install Varta (branded RAC) before that it was Bosch, going back a long ways since we had a deal with Exide (good batteries though)
I know dealer (Skoda) tech and they tend to use all 11111..s on the VCDS, so they dont have to wait around for the ODIS factory tool (I'm guessing that can just scan the QR code on the new battery for matching)??

I'm just doing a 15 plate passat now that has 11111111 new battery is 70ah old.one was 68ah
So far I've lost connection twice at the point of saving the data using Bosch KTS

Had to pop around to the factors I use, there standalone specific tool did it with ease.
Charging rate still seemed strange, but stop start etc all worked.
I could do with some more education on ecu controlled charging tbh.

So did you re-code it wth all the 1's?

Hey there, I was wondering if you knew what cars from the VAG group have the ability to "learn" whether a new battery was installed on them (without needing a manual coding). I recently replaced the battery on my Audi Q3 (2014 model) with a brand whose specs look better than the ones on the dead battery (which was still the VARTA factory unit). Since there is no way one could reprogram without using specialized tools I was wondering it this is a non issue or if I should go out and seek help to try and code the replacement battery. Thanks for your help! For most newer VAG group cars we have been buying and selling TPS supplied batteries (Varta or Yuasa) with BEM code stickers and coding them via VCDS.

You need to tell your Audi Battery Management System - it is dealing with a new battery.

Luis if you have upgraded the CCA/AH spec of the battery it would be a good idea to have BMS reset to match,the charging profile will be a little skewed otherwise If the battery chemistry has changed from EFB to AGM you can also change that in the BMS The 10 digit code is just a VAG admin thing, you can just put any sequence of random numbers you like like

Since ordering a new battery for the Tiguan, a couple of things have come to mind….
If the oem battery is being replaced with and equivalent sure nothing needs changing? That is, if it’s a Varta out and a new Varta in the the same capacity/cca ( or there abouts, oem is 68 new is 70..) How does the ecm know that it’s a new battery and not one that has been on an external charger over night say?
Anyway, I’m hoping swapping the battery out resolves the current issues..( no pun intended..) looks pretty straightforward now I found where to look…just a matter of updating the capacity figure and changing the serial number…qed.

Should be fine chippie. It isn't like BMW where it needs to know its dress-size alongside all the other information, it just needs the capacity and the (approx) battery-make/type to get the charging correct.
