URGENT HELP PLEASE

[A4ultra]

Dear Forum, I am new so please bare with me.

I am enquiring regarding obtaining some help, advice and a possible quote.
(2016 Audi A4 S line ultra)

Situation: I was driving on a busy inner city dual carriageway and heard scraping suddenly. I thought for a minute something was jammed in my wheel and was being dragged as when I turned the noise increased. I stopped at the nearest junction and saw a large metal object hanging out from underneath the car.
There seems to be no external damage to visible bodywork i.e the front of the car or the drivers door area etc. Looking closer it seemed that the metal object must have been on the road and got lodged in the car. I pulled it out with difficulty as it was really lodged in and it has obviously left a sizeable tear in the undercarriage.
I am asking to see what should be done and if any likely damage has been done? Can something be done about the hole in the undercarriage as I have had problems scraping it before also at my old property due to the gradient of the driveway. Should it be filled or could it have caused damage to the items underneath?

I frequently make daily 600+ mile motorway journeys so also don’t want any possibility of the vehicle being exposed to damage sooner than is necessary from the environment as I tend to keep the vehicle for as long as is possible.

I tried attaching pics however says it's too large even individually

What do you suggest?
Should this be filled/inspected for damage to other components? Is this common and unlikely to cause any problems? Should the undercarriage be replaced if possible etc etc

Any help would be greatly appreciated and if applicable please provide an estimated quote however only if necessary.

I have in the meantime contacted dealers etc

I think you need to contact your local dealer tomorrow.

Hey,

I've come to consensus that I'll take it to main dealer and an indy for a second opinion

I've managed to attach the pictures this time though
