Today I finally found the time to attempt to install the Frunk Suction device (an accessory to pull the front boot closed).
The basic installation was straightforward: remove the various trim pieces, unbolt existing latch, bolt suction device over the top, run the wiring. Took about 40 minutes.
After that, I spent the next three hours trying to get the installation to work properly. I should say that my front boot (sorry, I just can't bring myself to say 'frunk') is not perfectly aligned ex factory. I have got it pretty right by adjusting the black leveling screws under the leading corners of the front boot lid. Anyway, with the suction device installed, I experienced the following:
- when the various adjustments are such that the suction device will work, the front boot is not aligned (one side is lower than the other)
- when the adjustments result in a reasonably-aligned front boot lid, the suction device does not pull down far enough to engage the latch - it pops back up half way (latched, but not closed)
- various other adjustments also resulted in situations where the front boot could not be closed because the original latch was not aligned.
In the end, like
@dronus (I believe) I have removed the device. I could not find a combination of adjustments (there is some flexibility in positioning of both the original latch mechanism and the suction device) that I deem to be satisfactory.
I have some theories about just exactly why this thing doesn't work for me. I suspect the fact that I've had to make some adjustments to allow for a slight misalignment of the front boot lid mean that the suction device is applying pressure to the mechanisms in 'closed state', and causing a problem.
Anyway, I am going to write this one off as a bad call. In my month of ownership, I have so far never needed to use the front boot (I suppose that I'll have to re-fill the washer bottle at some stage, or I could just sell the car), so I think that reverting to fully manual operation will not be a drama.
Side note: there is a shed-load of clever-dickery under the trim in the front of the car. Absence of a spinning ICE dictates a very different approach to heating and cooling - and it's really interesting to see how Tesla handles this, and how cleverly it's all put together.
