aftermarket rear diffuser for 2015 535xi M-sport and comfort access trunk opening

All,

I've purchased this rear diffuser https://www.ecstuning.com/b-ecs-part...s/011818ecs01/ which accroding to ECS website should fit my car. Unfortunately comfort access trunk opening sensors (opening the trunk using your foot) and TPMS module are in the way. While I can relocate TPMS module, there is no way to keep comfort access trunk opening sensors if I want to use this rear diffuser.

Has anyone installed rear diffuser with aggressive look (similar to M5) that can accomodate quad exhaust tips on their car and was able to keep comfort access trunk opening sensors in place and working?

Thank you for your help.

Just because it fits doesn't mean it's the correct one; as in your case. You need one that accommodates Comfort Access.

Do you know which aftermarket diffuser can accommodate comfort access?

You'll need to buy the adapter that is listed in this post in order to keep your comfort access without having to cut anything up and relocate the parts.

Interesting! I was having the same issue but just let it be. Is it the absorber that I need? What does it do? Where does it sit? How do I install it? hahah

$40 to make the sensor work again is totally worth it. Help!

I did this upgrade on my 2012 M sport 535i using the adapter. the diffuser and adapter installed with no problem, but I could not make the sensor work. I also will like to know where are people putting their sensor for it to work?

I zipped tied it perpendicular to the ground and it does not work that way.
