wondering if previous owner code it out permanently, any way to check this?

I did register the new battery with bimmer link, but still not working

Why? Leave it off. It's bad for the engine especially the bearings.
This may be a silly thing to check, but the feature is off by default (thankfully). You need to manually turn it on by hitting the button.

Did you actually turn it on?

Also yes, it's horrible. Don't use it.
+1 leave it off, don't even worry about it.
