MAF sensor location

The Cam Position Sensor is a common item to fail. However, the cam positioning mechanism can fail too giving that code.
There are two sensors and the Exhaust Cam Sensor is most common to fail. I always replace both.
Te CKP's are on the top front of the engine next to the cylindrical operation solenoids.
Knock sensors fail too and need checked or correct feedback to ECU with a scanner.

These engines require regular oil changes with quality synthetic oils and OE filter....not a FRAM or WIX !
Buy only BMW sensors ...aftermarket have high failure rate.

If you are installing a so called "chip" don't do it, it can harm the engine due the changes it causes in fuel control as related to Intake Air Temperature and burn holes in the pistons. All that little part really is, is a $.50 (50 cent) resistor that you can buy from Radio Shack, it is smoke and mirrors and it also will void any warranty you may have. I for one strongly advise against installing it, it will make not difference in power and all there claims are just lies and falsehoods..

That plastic hose is where the thermostat is located.
