Manuals/instructions for fitting Closing Element 3V0807611A etc

Hi everyone

I've searched high and low for instructions on how to properly install the Closing Element 3V0807611A on my Superb 2020 (post face lift version).

After an unfortunate oil change diaster (garage didn't screw filter back on) with oil pooling on underneath plastic trays, which then flipped off while driving - which also caused the lower radiator slam to snap off etc!!.

I would be so grateful if anyone could over some advice or where I could download instructions.

Many thanks

Dave
