Just had my BMS updated.

It was 1125600R15

The BMS version is now 0210622EU1

I have read that the BMS version should be 1230621A01 (the January update)

I have also read that the updates are in the following order - 1125600R15, 016600R17, 0603610R28, 1016620R40 (supposedly the bad BMS), 1230621A01, and 0210622EU1

Can anyone tell me which is the latest update that I should have and is there a difference between 1230621A01 and 0210622EU1.

If there is a difference, what are they??

I love the car but I'm getting a bit confused with the BMS updates

Cheers

Did some more research and now no that 0210622EU1 is the latest BMS update.

Would still like to know what it does though

You need to buy a Bluetooth OBD scanner and download the app from the Project OBD2 thread.

This will give you all the Firmware Levels, SOH and much more.

This is the scanner I got

DIAG Scanner

You can download the App from here

Apologies if you already know this, but if you look at the first 4 digits of the BMS that gives you the release date (in reverse) so 0210622EU1 was released on the 10th February and 1230621A01 was released on 30th December. So 0210622EU1 is the latest BMS release.

Hope this helps!

I had seen this in another thread but only after I asked the question :mad:

Maybe I should do more searching before I ask questions lol

Thanks.
Why did I think these cost mega bucks🙄
Does it stay plugged in all the time?

They range in cost - mines was around £20, I think, but be aware some of the cheaper ones don't work with our car! I personally, don't keep it plugged in as I only use the app to check the battery's balanced mainly - there are some data fields that can be reviewed whilst the car's in motion so you'd obviously have to keep it in, if you want to look at that information.
