probably both, although a dealer is probably going to charge you more for it. check out "bmw coding" on google and you might find a local guy like I did, also you can pm Okee "OK" he has done several members cars on this forum and can code you remotely (he sends you a cable and you both go online at the same time then you send his cable back)
