My 2009 4.8 started smoking at about 58,000 miles. Thought it might be the valve stem seals and had those replaced, during the process found out I had a cracked piston (long story). Had the piston replaced and upon startup, the engine ran rough. Ran a scan with Carly for BMW and got misfire on bank 1, all four cylinders. Cleared codes, scanned again, and I'm getting 002A83 Camshaft control input. I need help on what to do to resolve the code please.
Appreciate any tips on how to troubleshoot and resolve this problem.

Also getting some other codes, 00A811, 00630F and 00A8C5, perhaps related to the car sitting unused for about a year.

Thanks for any help in advance.
