Seems to me that you obtained those codes using a generic scan tool.
It would be best to have a diagnostic scan performed by a scan tool with BMW diagnostic software.

Btw, I would first make sure that the sensor connections are correct, and not swapped, followed by an intake smoke test, as it may be an intake leak. Check intake boots and all vacuum hoses for brittleness and cracks.

same codes using INPA .vehicle has been smoke tested several times just to be sure no leaks found.have checked connections to 02s and reversed when i reversed them it set a code for being reversed then switched back the reverse code goes away the others stay . all 02 are new bosch sensors.i just cant figure out what is going on with it .thank you
