Wow, I wish more BMW dealerships were this supportive of its customers!

Wondering if they changed the kits for MY2021 for the gloss black rear trim?

Reason I ask, the 2020 trim kit lists a gloss black tow hook cover piece required for about $20-25 additional.

However, 2021 trim kit on the official site doesn't list this part. The order form when I placed my order also did not have this part listed anywhere, I only had the option for the rear trim kit and diffusers, as well as other m performance parts.

Can anyone confirm if I need this?

I did not order any additional parts. Only the lower bumper cover and the diffuser. Be aware that you have to cut of the end tip of the diffusor. I was struggeling with that a bit, but then I found a manual that says that you have to cut the end off. I think this is only for the M340i exhaust tips. Also make sure to attach the Diffuser onto the lower bumper part before installing this lower bumper part. It really need some pressure to click it in, when the bumper is installed this will not work.

I've just bought a G20 330e and was hoping to get this diffuser in gloss black and the m340i exhaust tips fitted. I wouldn't be able to do it myself, does anyone know where I could go to get the parts and get them fitted in the uk please?

Am I correct that you have to get one of the diffusers to go with the gloss black trim or it looks unfinished?

Yes... it looks like something fell off.

Hi, do you know if I could fit this diffuser along with the M340i exhaust tips to my 330e G20? I really like these shape exhausts they look so much nicer than the usual 330e style. Thanks

Resurrecting this one as I'm interested in the M-Perf diffuser with the carbon middle section. Is it true that the kick sensor for the trunk/boot has to be decoded as part of the installation? That seems to be what the PDF instructions say to do :/

For anyone searching later - I installed the OEM M-Performance rear bumper and carbon fiber diffuser trim and the trunk kick opener still works fine and hasn't opened randomly.
