I have a F20 BMW 120i, the car came with the standard single piston brakes. I bought a used M sport set with the 4 piston brembo calipers and 340mm discs all around. When searching online it says you need to code something into to the car when upgrading to M performance brakes(370mm front discs). Is this also the case for my upgrade to M sport brakes. Or can I run them without coding anything. And if I have to code them. Is that something I can do myself or do I have to go to a bmw dealer.

That's just front. Rear are different (your picture exposes it correctly).

Yes, 2NH or SPBR should be coded in
