Rubber thing under front bumper on Audi A3

[newa3]

Can someone help please.

What is the rubber strip under the front bumper called please?

I have lost mine somehow in the snow and need to order a new one but don't know what it is called.

Also what is the purpose of the rubber strip under the front bumper?

I've just had a look at the ETKA parts catalogue and the only bit I can see which goes under the bumper is called a 'closing element' and is listed at around £20 - part number: 8V3 807 233. The catalogue gives no indication what it's made from, but any dealer should be able to bring up the ETKA screen showing the front bumper with all it's parts.
