In the UK market, 2012 cars with the M-Sport package and the 35is get 7XA and non M-Sport Z4s get 2XA.
7XA -- M-Sport leather steering wheel with gearshift paddles.
2XA -- Sport leather steering wheel with uni-directional gearshift paddles.
7XA has the + on the right and - on the left. I haven't seen a 2XA car with automatic but I thought it has the other type of paddles. 2XA is listed as a no charge option on the US price list.
7XA is the steering wheel to get. I've tried both with MT cars. The M-Sport wheel is option code 710 in a manual transmission car. Same wheel but no paddles.
