Hi, I recently bought the car is a BMW 1 SERIES 118i 2012, and the engine light turn on, the error code is a P0172.

I already change the spark plugs, change the oil, clean the MAF sensor, changed a O2 sensor (the one on the turbo).
I also used a liquid moly Cleaner Inyector, I don't now what to do next I'm really tired.

Several times the light turn off by itself, but after some days it turns on again with same error code.


I would appreciate any kind of idea of what could it be.
