Registering 105Ah AGM battery in E61 with Bimmercode/NCS

Hi Guys.

I'm new to BMW and BMW coding. I'm also not sure If i should ask my questions in this section (E60/E61) or in the coding section. Sorry if I got it wrong.

I've been reading a lot of battery registration threads on the forums, but I can't find an answer to some of my questions.

I recently bought a used 530d XD -2008 with roughly 240.000 km~150.000 miles and have a few questions about battery registration that I can't find info about.

I just got the BimmerGeeks K+DCAN cable and also the Carista bluetooth adapter and started to play around a little with different programs and apps.

I started with trying out Bimmercode app (with the cable as Bimmercode needs a WLAN-adapter). The app told me I have a 90Ah AGM battery. I found this strange as I actually have a 105Ah AGM battery, which the previous owner got installed and registered a few years back.

I verified this with Ista D which also showed the same (90Ah AGM). However when playing around I registered a battery change by mistake as the battery still seems ok and won't be changed for now. Previous battery change according to Ista was at 177.000 km~110.000 miles which I assume adds up with when the 105Ah AGM actually was fitted in the car.

So I did some more researching and playing around and found out the following.

- In NCS Expert/Dummy there is (just as in the Bimmercode app) a selection for 105Ah AGM battery. This can be coded both with Bimmercode and NCS.

- When coding 105Ah AGM with Bimmercode, NCS shows that the car is reguistered with 105Ah AGM. Same thing but Vice Versa if coding 105Ah AGM with NCS, the Bimmercode app shows 105Ah AGM.

- However: when coding to 105Ah AGM with Bimmercode or NCS, Ista (as also the Bimmertool app) shows me that the car is registered for an 80Ah AGM.

- When coding to 90Ah AGM with NCS or Bimmercode also Ista (as also the Bimmertool app) shows the 90Ah AGM.

So here goes:

Question 1: Is there a way to unregister a battery change as it actually hasn't been done?

Question 2: When setting to 105Ah AGM with Bimmercode or NCS; is the car registered for 105Ah AGM or 80Ah AGM as Ista/Bimmertool says?

Question 3: Am I better off just leaving it at 90Ah AGM as before or should I use the 105Ah AGM setting where Ista/Bimmertool shows I have an 80Ah AGM?

Question 4: If the car actually can't be set for 105Ah AGM as it is; is there something I can do (for example update some ECUs with WinKFP) to get it corrected?

BR.
Stefan

#1- you can change the registration but the history will stay.
#2- I would believe ISTA over some app.
#3- If the actual AH is not in the list use the next one below. If you use the next one higher you are over powering the battery which can cause damage and shorten life span.
#4- Same as #3.

Hi.

Thank you for the information.

So I believe 90Ah AGM is the way to go, just as it was before (will register to 90Ah AGM with Bimmercode as it's the easiest way). Believing Ista is probably the right thing to do.

So this means I can't undo the battery registration. Don't mind about the history very much, but does this mean that the battery will get charged differently as the ECU thinks it's a new 90Ah AGM insted of a severeral years old one?

Hi.

Not very god at German and prefer Swedish.

As a newbie the first info i found about K+DCAN cables pointed me to BimmerGeeks website where I also found links to a lot of the software I downloades. Also got some updates from Shawn in the coding area on this forum.

Phone Apps downloaded from Google Play Store (Samsung/Android).

Yes it will charge it differently, it's probably going to shorten the lifespan a bit, that is what registration is about. Nothing can change that now except giving it an actual new.battery.

Hi.

Thank you for the information. I'll just forget about this until the battery needs to be renewed for real.
