Hi,
Eventually! There are two spring clips in the engine bay.
Just tight enough to NOT be able to release with your fingers, and just so inaccessible that you can't get pliers on them!
They are square in section, fortunately I had some bits of square section brass tubing laying around in the shed.
One of them was just the right size to push over the clip and compress it enough.
There's probably a special Vauxhall tool to do the job at several billion pounds .........
Stupid thing is, if you need to replace a front indicator bulb (reasonably common occurance I would think) ...... Yes....... you have to ........ Remove the Grille!
