There have been some discussion in various topics about the very high cost of BMW side mirror repair. Basically, this is complete assembly replacement.
In the original "mission statement" for the i3, the idea seemed to be as ecological as possible. Power for the factory comes from wind turbines. The car bodies are made from carbon fibre rather than iron. The wood trim is produced from renewable sources.
The original design for the side mirrors seems very sensible in that there is a plastic ring that breaks if the mirror is forced to move as the result of a collision either with a fixed object, such as a gate post, or in a road traffic accident. This avoids the mirror mechanism being broken or indeed can prevent the door being damaged as the whole thing is ripped off. This ring seems to perform the same sort of function as a fuse in an electrical circuit. Once a fuse has blown, it can be replaced. Indeed in times past, a fuse could even be required with fine wire of a suitable gauge.
It is surely not ecological to replace the entire assembly just for the want of this plastic ring.
Even to replace the entire assembly, removing the door panels seems to be a major hassle requiring new clips to put it back. What is wrong with replaceable screws?
I can see a business opportunity here. Publish instructions as to how to remove and disassemble the wing mirror assembly, preferably without removing from the door, and replace the ring. Print rings using a 3D printer and sell for say £100 -- still a lot for what it is, but much less than the prices (+VAT) charged by BMW's agents. If the business is operated by a single individual as income for his 3D printer, he is unlikely to make the VAT limit over a year, further reducing costs to the end user.
I can also see an opportunity to be really disruptive. Do as above and publish the 3D CAD file on the internet. Then even if the hapless BMW owner needing a mirror repair has no 3D printer he could do well by entering this new bit of the technology market and make his own. This sort of behaviour is "negative vandalism", ie doing something constructive that is also disruptive.
