Hi gentleman

İ have problem with my god dammed n13 116i  cylinder gasket changed after i made mistake and exchanged place of inlet and exhaust camshaft sprockets than corrected place but before start engine i deleted adaptation value of vanos . Car start an 3-5 sn after engine error i checked error codes ; 
164040 : intake camshaft installation faulty
120408 : charge pressure control : switched off as a subsequent reaction 
İ checked timing chain and sprockets bolt everything seems good order, checked timing also normal. İ exchange inlet and exhaust camshaft sensore but again same error. İ recalibrated vanos motor end position but nothing change .
Engine runs but a few seconds after rpm start hunting and gives fault ,idle unstable. 
What could be ??
