The benefits are debatable indeed. My car also already had the option coded in to open/close the roof by pressing and holding the key button.
The advantages of the module are:
- One touch open/close of the roof using the button on the dash, no need to hold it.
- Shorter press of the key to open/close roof remotely, no need to hold it.
- The roof operation doesn’t stop when turning off the car.
- Operation of the roof while in motion. With way the E85 roof folds in/out (it does fold up on itself, instead of more opening up as bigger convertible roofs do), I feel the wind pressure should be quite limited. For safety I have set the limit to 20 kph (although once it has started you could go faster), and would recommend only doing this while driving on smooth surfaces.
- It is my daily and regularly drive longer motorway distances, the comfort indicators (tap for 3 blinks) are in that use quite convenient to have when changing lanes, merging in/out. On the pre LCI cars I believe you otherwise need to fit a new light module and do some coding, so that offsets some of the costs.
- And there are some tweaks, like coming home lighting, hazard indicators when using the roof remotely, postion of the windows after opening the roof.
So it adds quite some convenience, but it is certainly in the ‘luxury/not essential’ category. For the 169 EUR it good value in my opinion, with the added 115 EUR shipping and taxes less so. But still fairly priced taking in account competing products, and functionality offered.
