I've used your guide today to replace my broken grill. I went with a standard looking one, you can't actually buy the original grill on its own from Skoda on its own, you have to buy the whole bumper, I was told. Anyway, good guide and thanks, I didn't read far enough down the page to see the part about releasing the 2 tabs at the back of the grill from the hole on top of it, so I was a bit confused at first. The left side came off with just a pull, but the right wouldn't budge. I found out later it was because as well as the other parts of the grill, the left tab was snapped and just fell off when I took the bumper off.
Really worrying trying to plastic weld the new grill in place, I also used some JB Weld plastic bonder on them to fill in the gaps. Looks like nothing ever happened now, also used the JB Weld to stick the vrs badge back on too.
