It cannot. I'm able to push mine up just a tad more (no real difference) and hold the button until it beeps. But that does nothing as it opens back to the original height. Mine looks like @JayPaul's. And yes, @terranx's white M3P opening does seem a tad higher than the retrofit. The retrofit definitely opens less than the manual struts.
To clarify, it is height adjustable, just that it can be adjusted lower than maximum allowed height (to avoid bumping in low clearance garages for example). If you are trying to force it beyond that it won't do it, except temporarily.
Tested out this morning and you are correct. Adjusted height lower and saved via button hold/beep. Next open was to that low height. Set back to highest level and saved again. So it certainly is height adjustable to any level, just doesn't open as wide/high as the manual struts.
Two ways to tell. If you go on your Tesla App->Upgrades->Accessories->Interior then at the bottom, should say Model 3 Powered Trunk Retrofit. If it appears then more than likely your car will support it. Older Model 3 will not have that accessory appear. Another way is to ask your local service advisor.
Thanks! I used your first method and the Trunk Retrofit does appear (although currently not available) in my app so I'm good to go when they come into stock. Is this one of those high-demand accessories that's available only for a very short time and then goes out of stock for weeks/months at a time?
I ordered my retrofit kit on the day that I got the notification that they were back in stock (23 October). It was reported as being out of stock again on 26 October so it would seem that either supplies are limited or demand is high. Prior to that, it was out of stock on 15 Sep (1 day after being announced as available) and remained out of stock for just under 6 weeks.
