Got myself ready to change the pollen filter on the G.
Warmed up with a series of stretches, touched the toes 3 times.
Went in, got myself under the pedals , couldn't see too dark. Went back got torch, wiggled clip, didn't move.
Found it was a clever lift out button thingy, pulled out clip. Trim didn't fall out as expected, tried some gently pushing and tugging.
No joy - Replaced button thingy, closed door, watched Grand Prix.
