I just got my new Model Y and my first impulse was to look "under the hood".to see what I can or should service when necessary. That started a chain of events that burned up my day.
I read the manual and it doesn't say much about removing the maintenance panel -- essentially to pull up to get it out, and to do a good job when putting it back.
I got it out OK, although I was afraid to break the thin plastic; so it took me a while, but nothing broke. I saw what I wanted to see, but I'm not sure it was worth it.
Putting it back on proved to be almost impossible. The main problem is that the front of the maintenance panel attaches to the rear of the thin plastic trunk. You have to push hard on the fasteners to insert them into their holes and the thin plastic trunk bends away instead of letting you push hard enough to get the fastener's into their holes.
I spent literally hours trying to get it back on . I got it on and I don't think I broke anything, but not all the fasteners are attached.
I can't believe that it is this hard -- especially since we all are likely to need to remove that panel at some point. There must be a trick. Does anyone know what it is?
