Brake light, ABS Sensors, WHAT ELSE!
Before buying any parts, clean the throttle body. My truck has under 50k mi and began to stall and give air sensor/reduced engine performance messages. Spent 20 mins cleaning the throttle body and no more issues. Can of CRC throttle body cleaner cost me $8. Whole job took under 30 mins.

And the K&N has had mixed reviews with D3 drivers. Apparently the oil can cause false readings to the MAF Sensor (Which is directly after the filter) which can then get covered in oil and fail.
I get the new MAF Sensor in on Tuesday. After the install I will post my results!

installed new MAF
I installed a new Mass Air Flow sensor, part number PHF000140 on Tuesday and have now put about 500 miles on my 3.
Prior to the install, I was getting an engine check light every 20 miles or so after having repeatedly cancelled the DTC codes via my Scangauge II. The codes displayed were P0171 and P0174, both called up as a fuel lean.
P0171 and P0174 - OBD-II Trouble Codes
So far, no more MIL light activation so I keep my fingers crossed.
I did not try to clean my existing MAF as it is the original plus the more I read about cleaning them, the less certain I am that they survive the cleaning process regardless of what one uses as a cleaner.
