2014 BMW 328xi MAF sensor

Where is the MAF sensor located on the 2014 model? I tried google and forum search and couldn't find any results for the 2014 model

If you look at your engine air filter housing, it has two pipes. The pipe closer to the front of the car is where fresh, unfiltered air enters. The pipe behind that is where the filtered air exits and goes to the turbo charger.

The MAF sensor is a small sensor that's attached to the pipe which receives the fresh, filtered air. To remove it, you'll detach the electrical connector attached to the MAF, then you'll unscrew the two small Torx screws which hold it to the air intake pipe. When you reattach, start these screws by hand. Do not use a tool. That's because if you start the screws with a screwdriver, it will very likely slip and the screw will fall into your engine, never to be seen again. Ask me how I know...

Unless the car has been driven in a very dusty environment or the engine is throwing a code, you shouldn't clean the MAF sensor. It is extremely fragile and only special MAF sensor cleaner should be used on the thing.

The reason I want to clean it is because sometimes at low speeds feels like gears are not shifting right . Same with stoping. It's not very smooth

A MAF is really easy to clean. But you must use special MAF cleaner; don't use anything else. It is very delicate so don't wipe it or touch it. You'll see the delicate wires when you remove it and you'll see what I mean.

In your case, it's probably not the MAF, but that's easy enough to clean one. The low-hanging fruit for solving a problem like yours is to check the air cleaner and check and/or replace the spark plugs.
