Aftermarket Polypropylene (PP) M5 Diffuser <> Comfort Access

spielnicht · 12-26-2021, 12:22 PM

Did some digging and came up dry on here and M5 forum. Already aware (from experience) that CF diffusers don't work, but anyone can confirm with certainty if those aftermarket polypropylene plastic M5 diffuser work 100% of the time with trunk comfort access? I know the genuine M5 diffusers are made of polypropylene as well, but curious if anyone can confirm if these aftermarket ones work.

With the correct part and modification it will work .
Will have to some trimming and relocating the sensors if using the OEM
None M5 adapter.

Thank you.

Should probably have mentioned already that I have the OEM M5 diffuser and adapter and know that comfort access is working. The issue is that most aftermarket diffusers, especially carbon fiber ones, block the motion sensor from working. I'm just trying to verify if these particular aftermarket diffusers made of polypropylene work just like the OEM M5 diffuser or also have issues.
