how to disconnect MAF sensor connector
Hi, Guys:
I plan to clean the MAF sensor but could not disconnect the connector. I have 2013 X5 xDrive35i and the sensor is located in the back of engine. Can anybody shed some light? I have attached a photo. Thanks. |

You might be able to clean it without unplugging it and instead just removing the whole sensor from the pipe. There's only 2 torx screws holding it in, then just pull firmly outwards (there should be an o-ring on it that makes it fit snug).

Thank you guys, I did it today. According to the attached picture, I could not figure out how to remove the air filter cover from #1 on the right end of #3 so I decided to pull the whole thing out from #1 on the left side. That worked.

Actually, the sensor was very clean and did not look like any dirt on the wires. I cleaned them anyway but it may not need cleaning frequently. Someone suggested that it should be cleaned every time when changing the air filter. I am not so sure about that.

The MAP on the other hand is right in front of the throttle body and sees some oil vapor from the turbo. I could see that getting dirty. I will be changing out my charge pipe in a week or so I will take a pic of the MAP when it's out. |

Funny, I actually find detaching from the right side (when facing the engine, air box side) easier. I just loosen the clamp and pull/wiggle the airbox up and out...

How did you pull the rubber locks (shown by the red arrows) through the plastic ring (shown by the green arrow)? I was afraid to break the rubber locks so I loosened the other end of the pipe. I would be interested to see your work on the MAP sensor. I think it is much easier to remove with the space given.

We might have different connections there. Looks like that pipe the MAF is in was changed for cars after 4/2012. My car is 1/2012 so I have the older pipe.
I didn't pay attention to that connection to be honest. I just loosened the clamp and tried to rip out the airbox... Quote:
