Replacing battery / radio code?

[tonymor]

I’m needing to replace my e89 zed4 battery and no where in the handbook is their a radio code which I’m sure I’ll need after fitting. I’ve contacted dealer but if they’ve a negative reply any advice?

I recall changing the battery in a couple of old cars of mine, an e46 325ti and a 330i e92, I don't recall coding anything. I've heard stories on here that batteries need coding, but I've unplugged batteries many a time and fitted new ones and the radio and everything else has been fine

No code needed.
