I bought these:

For my 2014 116i which also only has the limiter.
I've not yet fitted them but have installed e-sys and Bimmer Utility to get my head round the coding.
The alternative would have been to replace the steering wheel as there were some on ebay at the time.
I also plan to remap it using MHD wifi obd adaptor and phone app.
