I don't know of a video but to remove the scuttle panel you will certainly require the replacement of the 4 clips.
These.
Remove the wiper arms first then you pop the 4 clips out by pushing the centre down and through the clips then pull what's left out. The two philips shaped plastic screwheads in the centre need to be very gently turned 90 degrees. Then the scuttle panel will lift off.
I ended up having to remove the rubber sound traps from the inside eventually after they blocked again after I did what I did in the above post. I cut a few mm off the end of them before putting them back to stop them re-blocking. Not an easy job.
