That document indicates that - for all M Performance parts dealt with in that document - coding is only required if installing the diffusor.

M Performance rear spoiler (M235i + M2)
Got a PM with the following question from a forum fellow:
"To your knowledge, is there any aero data out there on the carbon rear spoiler when installed on a 2 series/M2 ?To my knowledge, no detailed information has been made public at this stage. However, maybe the excerpts indicated below may be of any help. - The BMW Parts Catalogue shows M Performance Parts and indicates the requirement of also getting the front bumper winglets when opting for the rear spoiler (see here - to access: see here): Rear spoiler, Carbon (part # 51 62 2 334 541)- M2 Press Kit, pages 14-15 (see here): "The large front apron with trapezoidal blades and the Air Curtains in the outer air intakes recall the type of protruding spoilers that have been a familiar sight in motor sport down the years. For the BMW M2 they were inspired in particular by the BMW 3.0 CSL touring car racer. However, the large blades are not only a nod to the past. Form follows function is the message here, so as well as underlining the wide track of the new BMW M2 they divert part of the airflow through the wheel arches, while the Air Curtains guide the air effectively past the wheels. These two features work together to reduce air turbulence around the front wheel arches, cutting drag in the process.- M2 Technical Training, pages 10, 14 and 15 (see here): "BUMPER, FRONT- Interview with BMW representatives about M2 M Performance Parts (source: here): "Q: Are the front bumper winglets and and rear wheel winglets functional?

As you know, 'Comfort Access' allows you to open/close both doors and bootlid + close sunroof, without requiring to push the key fob. The German M2 price list specifies indeed 'bootlid' (Heckklappe): the possibility to open the bootlid with a touch. However, if it would equally include the "Smart Opener" feature (requiring the 'kick' movement), it would be indicated. It seems that the author(s) of the M2 Performance aerodynamic parts installation guide, copied text from the M4 installation guide. "Smart Opener" on a 3er:

And that's what you see and read on the configuration page of the M2 and the 3 Series about the Comfort Access. A rather clear and distinct difference.

Yeah, makes sense now. Thanks for the clarification. I just thought that all new BMW's with CA had the Smart Open feature.
I cannot find Smart Opener in ETK either so I guess Luc is right in that they have just Ctrl+C & Ctrl+V'd the F82 instructions.

It is pretty fucked to fit those front things. You are going to break them in any parking lot or speed bump, especially if you fit a different lower suspension. I wonder what a dealer will do with this. Those front and side things are like 900 EUR for a pair. This is not cool at all!! MR |

I am sure you will ever notice the "upset balance of the car" if you only fit the rear spoiler.

"I want an M2 with the ride height of a 320xd on shipping blocks." - said no one ever.

In all honesty you will not feel much difference if you only fit the spoiler. It is not a wing! And I am not going to drive five laps of the Ring at high speed every single week. Only time when you might feel it is doing a topspeed run on the autobahn. Although I never felt anything when I had the spoiler on my 135i and took it to 300+ kmh. MR |

I am still worried that when you fit them, you hit the front one while parking or entering a parking garage, and the rear ones will be kicked off by someone who wants to vandalize your car. (Too much movement) I could also see some (lowered) M2 driving over a speed bump getting into problems with those wings positioned just in front of the rear wheels. Another point is that they mention in the manual that the rear bumper has to be removed to remove the stock diffusor. I think you can do that without removing the bumper as long as you have enough space and long fingers. There is no information in the manual what kind of changes or coding is required. You would expect the coding would be related to the damping setting between sport and normal. What else could they have to update? MR |

Plenty of speed bumps here too. One of the reasons why I didn't lower my 135i Coupé. With the stock suspension I never had problems on these silly things.

I have 10 speed bumps just to get to my house from the road each and every day and a lot more in the city but I have never had any issues even with a lowered car. I don't slam my cars though.
