If it doesn't work very well on your car have it checked out by the dealer. On my car it works very well, easily 9/10 attempts on the first try. However I had a loaner recently in which it was very hit or miss getting the trunk kick to work.

think of your foot as if it were riding a swing. it needs to go up behind the bumper, not just under it

I can't comprehend how so many have an issue with this. It's such an intuitive thing. I've never had a single issue since day one.
You don't need to get anal about pointing your toe, lining up with the roundel or thrusting your leg in a certain manner. Just walk up and give a quick kick in/out. The sensor is up behind the bumper. It measures the longitudinal movement of your foot fore/aft. It does NOT use the park sensors. Distance from the bumper isn't particularly important (vertically). It has enough range to reach the ground. It also has a pretty reasonable range side to side. I literally just walk up and give a quick kick. Works 100% of the time. Don't overthink it. |

I had a loaner recently that had the CA. Didn't have any problems using the kick/pull back technique. I've read in another thread that updating the software helped improve the success of opening the lid.

I know it's "supposed" to work as I've got it to work, but, it doesn't work every time. My success rate is about 6-7 out of every 10 attempts. If this were implemented correctly we wouldn't have to have several threads about this very issue discussing the "proper technique". If it were implemented correctly it should work EVERY time you try it. I know a technique that works every time, use the button on the fob or simply use the button supplied on the trunk lid. Don't forget you have to have the fob in your pocket, or you'll just end up looking really silly continually kicking at your cool cars butt. |

Yet, here we are again with another thread on this subject, over thinking it. I know how to do it as it's worked for me many times, and yet it doesn't work every time. As one poster suggested maybe something is wrong or out of alignment with some of these sensors. It just shouldn't cause this much issue for something that is supposed to be easy to use and part of "comfort" access. |

I recall a TV ad that had a dog wagging its tail under the rear bumper and caused it to open; believe it was on the E90 series. Maybe BMW was getting complaints of the trunk lid opening unintentionally?

Here are the "sensor wires" that are mounted behind the bumper.
Each sensor will detect the movement of your foot (or any object) as it passes under it them. The sensors can detect the direction of movement of your foot by evalutating the timing of the trigger events from each sensor. The motion itself is not what triggers the opening, it's the rapid change in direction. You need to make a pretty quick and purposeful in/out motion, not a lazy wave. It's not like a typical motion sensor. Just moving your foot around isn't going to trigger it. Thrust with purpose! |

I have NEVER failed since day one and when I tell my friends (incl. my mother who knows nothing about tech stuff) who doesn't know that it exist to kick behind the car they also make it on their first kick. |

From my experience it seems to fail only when I accidentally touch the sensor. The trick for me is to not touch the car and almost wave your foot in and under the bumper in a rapid but somewhat circular motion. Hasn't failed for me since I figured that out.

you dont need to kick quickly...
Actually, a slow kick in and up, then gently pull swing back out your leg and voila fast is no good... try a gently kick up and pull out...

im batting about .500 now... in fact first time i tried it when i left work it worked.
it's not so much that i was or anyone is over thinking it. it's more figuring out how it needs to function. I'm not surprised some people have issues w it... it's sort of advertised as a 'just stick your foot under it' and it's not exactly that simple. it'd be the same thing as if to lock your car you had to snap our thumb back instead of just touching the handle.

I've been trying to figure this out for six months and have yet to master it. I think I have gotten it work a handful of times. It does work though its awesome!

Believe it or not, I didn't know my car had this feature until I saw this thread...LOL! My Client Advisor never mentioned it and I never looked into it.
I just went outside to try it and nailed it on my first "kick." Ha Thanks!
