Solution: BMW 225xe hybrid battery problem. Replaced 7.6kWh to 10kWh. High voltage battery teardown

I had Drivetrain service request on my BMW 225xe.
The official BMW service centre diagnosed problems with Cell Module 1 and recommended to replace the whole battery for approx £8,000
I found a used battery on Ebay for £1200 and replaced it in Cleevely Motors for £600.
Then I disassembled the high voltage battery and found a problem - one cell of 80 is bad.

Nice video. Having the same problem on my 225xe from 2017. Struggling to find a company to do the same work in Portugal.

Hello Nail,
Can you answer any of these questions? It would be very helpful.
Thanks 🙂

Hi! I'm sorry. Just saw the questions and answered them.

Thank you for the video, I would have loved to see where the battery is stored. I have a BMW 225xe and the battery is probably not good anymore as I can only drive a few kilometers using electricity. Do you know how to check the modules remotely using ODBII?

[@tatarnail]

Hi! I had the same problem - just few kilometres on electric charge. There are options to check the battery health using OBDII, but I don't know whether they show voltage on each individual module.

After replacing the high-voltage battery, it must be registered in the car's on-board computer? Was it easy for you to get it done at the place where the replacement was made?

[@tatarnail]

Yes. The service center did coding.

Hi Nail. Nice video. Which company change the battery for you please? And do they require coding for changing to bigger battery please? Thanks

[@tatarnail]

Hi! The battery was changed by Cleevely EV in Cheltenham. www.cleevelyev.co.uk/

Thanks for the video! Do you know which batterypacks are compatible? There are F05 (For BMW 2 Active Tourer, 7 kw/h ) and F48 Battery Modules for x2 and 10 kw/h which look exactely same. How wan the battery-pack be removed from the car?

[@tatarnail]

I used F45 model battery. As the battery is very heavy and difficult to remove - it's better to find a proper service center.

Did the garage have to do any coding to get the car to accept the higher capacity battery?

[@tatarnail]

Yes. They did the coding, but I don't what software they used.

[@tatarnail]

Hi! Yes, it did solve the problem completely.
