Q5 (2012) something hanging underneath

[King Mustard]

Can anyone recognise what this may be?

Hello Elliot,

Looks suspiciously like an undershield for - part of the transmission??  
I guess you will be able to crawl under and temporary secure it, or indeed remove it. 
Are you intending getting it looked at by someone who has the facilities to properly re-secure it?

Kind regards,

Gareth.

I agree with Gareth on this.
