Has anyone taken out the polestyrene block which fills the void beneath the loadspace floor of the 7 seat 110?
It looks like there's probably 30 more litres of space filled by fairly useless filler which holds the scissor jack and locking wheelnut.

I had a go but it seems to be fixed with either adhesive or clips.. I don't know if I should just wiggle and pull, or if there's a trick to it.
Anything detrimental to removing the filler and using this space?

 

I have thought about doing this exact thing, but ran into the same issue you did. I am also curious as to if anyone has actually ripped the thing out.

 

Same here on my 7 seater. Doesn't seem to want to budge. It has occurred to me to chisel away at the styrofoam to break it into pieces to remove it but have not been so set on it yet. If I do I'll post up about it.

I'd love a bit of underfloor storage to throw a few small things -- I don't even have kids, there was no reason for me to get a 7 seater !

 

I did see a thread where someone lost a stylus and an AirPod down there while sitting in the back and they were able to pull that piece out. Sounds like there are a lot of wires below it.

 

I had a go at it some time back. Got it half way out and gave up. The 48V battery is back there so I figure treading lightly is the way to go. Not my forte.

 

I took mine out (7-seat P300), but I don't recall exactly how did it. I think I just pulled the corners around the plastic interior trim that overlaps it. If you fully remove it, you will need something to support the folding floor piece. I ended up precisely breaking my foam piece in half and putting the piece that covers the air compress back. The side where the jack was stored is a lot of space. There are some electrical modules on the floor under the foam. I built a small plywood platform that bolted to the floor to cover the modules and was able to cram a 100a lithium battery and redarc bcdc in that space. See photo. Please ignore the messy wiring and dirty interior. Also, that metal silver piece withe three bolt holes was bolted to the floor where the battery now resides. No idea what it is, but never had to unplug it when relocating.

 

basically no point pulling it out on 7 seater.
