I am the sad owner of a 2006 E83 with 105,000 miles. The car was been great to own until I reached 90k and had a rash of problems with the X Drive System and various other problems that required replacement parts (washer pumps, water pumps, tire pressure sensors, speed sensors). The reliability of the electronic components is a huge issue for these cars. I have the Bentley Repair Manual, RealOEM for parts research and the Bavarian Technic Scan Tool for Windows PC's which have enable me to do most of the repair work. I have a current problem that is generating a "Service Engine Soon" light. I am generating a DTC 2882 and 2882 Fuel Trim and a 276D Tank Ventilation System which suggest that the car is running lean or rich. I am also triggering an occasional 2742 Misfire Cylinder 1 and 2774 Engine Shutdown Time. I clear the DTC's, the light goes out and after a week or so of normal driving the 2882 and 2883 reappear and on occasion the 276D. My research suggest that it is either a vacuum leak, a bad PVC value, a bad fuel tank vent value or a bad fuel pump and or filter. Given the combination of DTC and the occasion misfires I am leaning towards the fuel filter or fuel pump as the source of the problem. Can suggestions that would narrow the likely source of the DTCs would be greatly appreciated. There is nothing more frustration than making repairs to systems to only find out that it did not fix the problem.
Regarding the 276D code, remove your gas cap and inspect the rubber seal. Take the seal out, clean it, put a thin layer of oil on it, reverse it, and re-install....that is only if it looks OK. If it's not good, replace your cap. This may not resolve your problem but it's worth a look. It's possible that the tank vent code is related to the 2882 and 2883.
Regarding the 2882 and 2883 codes, take a look at these videos:

Regarding the misfire code, I'm thinking that it's not connected and may be due to a weak spark plug or coil. You might want to switch the coil with another cylinder to see if the code moves. If the code re-occurs in the same cylinder, move the spark plug to see what happens.
....or you could take the vehicle to an independent BMW shop to have them run a full diagnostic to hopefully pinpoint the problem to reduce your need to troubleshoot.
Good luck and report back with your findings.

Thanks for the advice. Looks like the hoses associated with the PVC system are prone to failure so I will start by inspecting and replacing the hose that goes from the oil separator to the drip stick and go from there. Will report back on my progress.
