[flagged charger]

Hi everyone. I have recently acquired a 2011 535i 6 speed manual. It has a few issues, but the one that I think I am going to have some trouble fixing is the Check Engine Light codes(2), being 101F01 and 104301. The check engine light is always on(doesn't come and go). I was told to check and clean both the charge pipe and the Manifold Absolute Pressure(MAP) sensor. I cleaned both of them and still had the codes. I ordered a MAP sensor from ECSTuning.com and installed it, and cleared the codes. The CEL came back on, however the codes had changed to 101F02 and 104302. To me this means that it went from pressure to high to pressure to low. This had led me to believe that I may have ordered the wrong MAP sensor for my car. I cleared the codes again to see if the same codes(101F02 and 104302) came back, they did. So changing the sensor has altered but not cured my issue. Any ideas on what my next steps should be? Any help is greatly appreciated.
