2006 E350 CEL and engine vibrations despite multiple part changes

W211 2008 ( E350 ) and my engine light came on , now i have 215000 km done , and i checked it with mechanic and the test gave 3 codes :
1. (1208) / Constant adjustment of intake camshaft of right cylinder bank in direction 'Retarded' (P0016).
2. (1200) / Constant adjustment of exhaust camshaft of right cylinder bank in direction 'Advanced' (P0017).
3. (0502) / Component A16/1 (knock sensor 1 , right ) has a short circuit to ground (P0327).
if anyone can help and advise regarding this matter i would really appreciate it .
i also check the MB effected range of the engines , and mine was not one of the effected.
( The car runs fine , but am afraid that it would suddenly stop or have problems )
Thanks in advance.
