Anyone know what this is

Is it important will I need to take it to a garage ASAP to have it put back on?
Not essential as you still have jacking points on the sill. You could just shove it back in the hole with some araldite adhesive or suchlike .
Presumably one of the 4-point hoist lifting points? (or a cover for it?) I was under the impression that they shouldn't be used for normal jacking anyway, for that you use the sill jack point.
As others have said front jack socket, left hand side! For future reference the part number is circled:
Floor pan isn’t designed for the car to be lifted from one of those single points.
All four in conjunction with a four / two post yes as it spreads the load.

Floor pan or not I’ve been told by a mechanic friend it’s not for jacking the car from a trolley jack.
The four points are for one simultaneous lift so the load is spread

Oh well then... if your mechanic friend said so
Hmmm friend who’s been in the trade 30 plus years or Danny from a Forum

I haven’t got any concerns because I don’t use them and never will.
Plenty of discussion on this very forum about them.
Official Audi procedure for non E-Tron & G-Tron A3
All indicate lifting from the reinforced cill sections.

Of course lifting form the sills is the prescribed method, no argument there mate. Most MBQ cars don't have the jacking point pads that we do on our cars, but many add them so they can have the convenience. Don't think anyone has reported their car bending in half yet
Not me anyway

Thats just a plate under the car beyond the front wheel inner fender

Regarding lifting from the reinforced sill position... do you place the jack on the actual welded seam, or should you use something on the jack to apply the load either side of the seam (like one of those rigid rubber 'pucks' with the channel cut out of them)?
I have always used a 'puck' on my A3's when using a trolley jack to protect the paint/underseal in that area I have never had to use the oe jack. I would thoroughly recommend a 'Puck'
As an aside my current S3 came with a steel scissor Jack in the boot, whereas for several A3's now they have all had an aluminum contraption, what have others got in there boot???

Yes, I understand about using something to protect the paint/underseal, but that's not actually what I meant - the question is do you use something to apply the pressure to either side of the seam, or just push against the actual tip of the seam??
I think the best solution is a puck with a cut in the middle, so the main load is spread either side of the seam, with the depth of the cut being about the depth of the seam.
Yeah, that does seem logical to me, but I sense we are all guessing really! I'm sure the car will have been designed to take the weight one way or another, but it never specifies this anywhere... or at least no where I've seen.
I bought a thick-ish puck, about 3" diameter ( can't remember where from ) and cut out a slot for the seam.
Works a treat with the boot jack or my trolley jack.

I think that you are right, the sill is designed to take the weight of the car vertically through the seam, I do not know what the construction is like inside it but assume that there is a vertical piece of steel which takes the weight and the formed sections of the sill we can see hold that piece straight for strength.
I bought my 'Puck' off ebay and it already had the groove machined into it sold for 'Audi' - it wasn't much, the groove is not as deep as the projection at the bottom of the sill so it gets compressed before any load is applied to the curved sections we can see. I have used mine many times on many VW cars Lupo, Golfs, A3s and A4s so have tested it quite extensively. I think the grove is more for location and works well as that.
Having said that because lifting on any paint represents a risk of damage I will always chose a subframe, wishbone etc. and quickly support the body on several substantial blocks of timber, again because I feel axle stands present the risk of damaging the body if not protected.

Yes, I think that's a really good point about the groove being for locating it, rather than to apply the load either side of the seam. I've got a couple of those pucks for my axle stands as well - they compress a lot, but it prevents metal to metal contact between the stands and any part of the car.
