how many miles are on your car? Has trans been serviced? Usually a code 48 indicates a transmission going south but you never know. Is the car running rough? If only one cylinder misfire is indicated usually it's a bad ignition coil. As far as the cam sensor code goes, I'd replace intake and exhaust cam sensors (Use genuine BMW sensors) and the o-rings as well. I've tired the Febi sensors and believe me you're not doing yourself any favors b/c you'll be doing the job again in like a week. HTH
