Code P0101 or 2645-1 Mass Air flow Sensor "FIXED"
After trying for over 3 months to get this code out of the vehicle, I finally took the car to Mercedes Benz shop and get this fix. It started when I replace the y shape intake tube because it cracked on me. After installing the new part, check engine light came on. Did search on different forum and did different solution to remove this code, with no success. Here what Mercedes Benz did to fixed it. "RESET ADAPTATIONS FOR AIR MASS SENSOR THAT IS REQUIRED AFTER SENSOR REPLACEMENT. FAULT NOW WAS ABLE TO BE ERASED". I just want to share the solution just in case you have the same problem. Total charge is $168 for labor.
