So this post is for the novice-novice, so please no groans from our pro's.

I've owned my car for about 4 years and only just noticed the bracket on the petrol filler lid...and worked out what it's for!  (It's probably in the owners manual which did I read & forget 4 years ago.  In my defence...I am old!

It's a handy feature especially if you have 'lost' the tether strap on the cap.
