Comfort Access with M Performance Diffusor
I was really disappointed when I found out that the carbon Mperformance rear diffusor for the F82 will disable the comfort access trunk feature when installed.
I know it's not a HUGE deal, but Mperformance parts should retain all the OEM features of the car With that said, has anyone found the sensor? I was thinking I could potentially mod the sensor or the diffusor (or both) to keep the comfort access feature. Searched around, couldn't find anything, any help is appreciated. |

if you look under the diffuser there is a little black strip with 4 black circler sensors thats it if in not mistaken, I was thinking the same thing too but I need to take better look at it maybe if we extended the wire and moved the strip to one side of the bumper instead of keeping it in the middle

Ideally I would like to cut a small hole in the carbon diffusor with a dremel if possible, but that will depend entirely on where the sensor is located and if it the hole will be noticeable. |

dont think you can drill in that spot I got the RKP diffuser and it should be here next week, but judging by the pics that I have seen it looks like they are located somewhere in the middles of the fins ( cant really explain it I will look for the pics for you ) the best option is to move the whole strip.......option number 2 was to put down anything I was carrying and physically open the trunk, but that needs alot of RnD

Thanks for the picture, I guess it is the black "4 dot thing", but now I'm interested to know what that other antenna like thing is in the picture, anyone know? If the antenna is also part of the function they will be tricky to relocate together... Either way, dremel mod is off the table based on this picture. Relocation seems to be the best bet but I will need to get my car first before I can mess around with these things. |

Anyone compare a stock diffuser with the performance one to see what the difference is that is stopping the trunk sensor from working?

So, I'm guessing whatever signal the comfort access sensor is using, it is not strong enough to penetrate the CFRP. Now I really want the solution to be boosting the signal... |

sensor wire signal to weak?
Hello together
did you guys found a working solution for the food swipe problem with the carbon fiber diffuser? I run in the same situation with the original M performance parts cf diffuser here in germany. Actually i am waiting for a reply from bmw directly. I will post the answer. Did you have success with a "dremel mod" or relocation of the two sensor wires, or with a signal booster? I think the two sensor wires detects the motion (change of electrical field) between the two sensor wires. Carbon reflects this field to much. I think if we drill multiple small holes or better drilling a slot along the sensor wires it could work. Any suggestions? For me it works fine until i tighten the inner screws again! No solution, but i will check this again. please answer Any success? Helmut

I was a little disappointed when I found out that his feature would become void after the install. Then I asked myself: What is better, the invisible kick under my rear bumper or a carbon fiber diffuser. Clearly, I went the the latter.

BMW answered today, that cf is the reason for the reflection of the signal. The will ask engineering for a possible solution, like "dremel" mod" I am interested how the singnal wire works and fgure out the best position for the holes or a slot. They told me, that cf is a bit dangerous to cut, because humidity destroys the diffuser after a while.
I agree with you: Diffuser is better, but we did all pay for comfort of this kick.. I will send an update.... Helmut

Hi guys...
Given CF blocks the signal, would a diffuser made of another material block the signal as well? Material such as FRP (fiber reinforced plastic) or polymeric materials? Any info? Thanks. |
