Seems a very simple thing to do if you can access the bolts that is…
The space in there is so restricted I just cannot see how to tighten the left hand side bolt for the bonnet hinge - I can locate a small socket ratchet onto the bolt but there just isn’t enough room to get your hand in a position to tighten it.
Looks like you’re not getting any help on this in here…
I have only had the bonnet off once way, way back, and whilst I can’t remember exactly how i got it all back on again, your pot does remind me that it was one of those jobs that had me regretting removing it in the first place!
As it’s no different to an Elise - it may be helpful to do a search in SELOC - I’d imagine the issue has come up there a fair few times.
