How does one put together a correct long adaptation battery code?

[Liky]

I replaced the battery on a 2014 Audi Q5 2.0 TDI. And I am not one of the lucky ones that have an "Adaptation" option which asks you for capacity and tech and similar, like all the videos around show. Instead I have Long Adaptation which takes a single 26 character long string and from it I guess it deducts all the needed info about the battery, the type of adaptation is determined by the electronics inside the car from what I understand. So my original battery has a special sticker on it which contains all the needed codes for the adaptation, a BEM code. But you can not buy a battery with such a sticker from the store and actually the original battery is no longer in production anyway. So here is the original long adaptation code in my car: 4F0915105E JCB 240624O2TR it corresponds to a Varta 12v, 92Ah, 860A AGM battery made in 2014. Now I am replacing it with a Varta Dynamic AGM 12V 80Ah 800A, what is the new value I have to enter for the long adaptation? Here are photos of the new battery and those are all the codes that are present with it.

Varta again, it makes me sick to see it. What a poor performance battery that is.

The original one lasted 12 years and I could have squeezed probably one more year out of it if I really pushed it but it was showing it's age in winter. I mean that's more than enough I have no complains with the performance, but how to code this thing correctly?

First you HAVE to post an Autoscan from VCDS.

Using the classic, Windows-based VCDS: Also, please wrap your Auto-Scan data in CODE tags, like this: Chassis Type: 4G0 Scan: 01 02 03 05 08 09 0E 10 13 15 16 17 19 28 36 3B 3C 42 44 46 47 52 53 55 56 5F 62 72 82 84 85 8B 8E 8F 90 VIN: WAUBGAFC5CN015352 01-Engine -- Status: OK...

I don't have an Autoscan with me, sorry I can not provide one, but also it is not needed for the purpose of my question. Not only that but I manage to start putting the puzzle together. In my case only the first part of the code is important, the second one is the manufacturer, fine I can type VA0 for Varna but probably any will do, and the third part - the serial number it only needs to be something different than the previous so car knows its a new battery. Now lets focus on the tricky first part which tell the car the type of battery and capacity. I have a 80Ah, AGM battery so here are the numbers closest to mine that I manage to find:
75Ah – (AGM) 3D0915105H / 000915105CD
92Ah – (AGM) 4F0915105E / 000915105CE

Now the question is, if no one knows a code for exactly 80Ah which is better to use, a 75 or a 92 in my case?

Ah, but it is necessary for the purpose of this forum, which is to provide support to users of legitimate Ross-Tech VCDS systems.

I would use 75.

Many thanks! In my case I went to a nearby store which sold me the battery, and the store uses VCDS so they tried to do the codding but then the employee saw "Long adaptation" and did not know what to do, he was used to the more common just "adaptation", so he proceeded and tried some random codes. Then I came here to ask in order to go back to the store and have them recode it correctly. Now I was thinking something, there are groups of car batteries by size, H7, H8 and so on. The dimension of my Varta 80Ah fits the H7 group which corresponds to the 75Ah code above, my last battery was 92Ah with larger size and was in H8 group, so if one does not have exact match by the capacity one can go by the group which should lead to same result or very close to the optimal. With that said we can put this matter to rest.

I would doubt that your store happens to have genuine VCDS but I could be wrong
