Retro Side Assistent

So,

The Octavia 3 only received the Blind Spot Assist with the facelift. That means it uses the 5Q generation control unit.

Of course, I'm not installing anything like that. Therefore, I'm using the OEM 5Q0 radar mounts with the 3D-printed adapters, just like @Lutz91 did in his Superb.

The OEM LED is integrated into the mirror glass, but I'm definitely not going back to that solution.

Through a bit of luck and some internet research, I discovered that another Volkswagen Group vehicle also uses the same Octavia 3 mirror caps.

This vehicle has the Blind Spot Assist from the factory with a version integrated into the mirror caps.

Thanks to @Lutz91 for finding the details.

So, I ordered a set of primed left and right mirror caps from the aftermarket, just to test them. VW charges €75 each, but I paid €35 for both aftermarket caps in Spain, plus a few euros for shipping home.

Thanks to @Lutz91 for the detailed research. The following parts are required:
