Hello everyone I was wondering if anyone could help me I replaced the valve cover gasket on the driver side as it was leaking a tiny bit of oil and causing a small white cloud of smoke while reinstalling everything I forgot to connect the camshaft sensor so I immediately shut to truck of and connected the sensor but I'm now having codes P054D P054B P0122 P2139-09

Well I was able to resolve my issue, I uninstalled the valve cover which weren't line up correctly so I took everything back apart and that time I decide to disconnect the battery and alternator power cable a day before, so the next day I installed Hylomar Blue M around the whole valve cover gasket after that I took off both off the camshaft sensor on the front drivers side bank of the engine and cleaned them with carb choke/parts cleaner and when I installed them back I swap them around so I put the bottom on the top and top on the bottom after that I reinstalled the valve cover made sure it was line up cover, fuel injectors, and cleaned up the coils with WD-40 and a Q-Tip to because the connectors because 1 had a little rust and sprayed all the connectors with WD-40 to make sure the pins had good contact once everything was installed and lastly added a quart of oil so I turn the truck on and off without starting it to build fuel pressure once that was done I scanned and clear the codes turn off the truck turned it back on but didn't start it the let the truck figure itself out after about 1-2 minutes of that I start the start which didn't start to start because of the fuel pressure so I trun it of turn it off and on 3 more times and started it and came on a little rough but smooth out and that was it no code no smoke I took it for a test drive and a little smoke because the 6 and 8 cylinder bolts weren't all the way tighten after the it was finally done hopefully this helps anyone who had this issue as I haven't found anything for those code because's BMW people having it and what to do the fix it which was changing the oil so yeah hopefully this helps
