I know it's resurrecting an old thread.
But I found the part number on my (64 Plate Superb Mk2) felt still clearly etched in the fabric today, should anyone require it?
The part number is 03L 103 660 C and it is called an Oil Pan Cover or Lid:

They're some serious money, 3 figures worth in pounds alone. However, the previous workshops didn't know how to do an oil change without saturating it in old engine oil!
So I'm going to be learning how to degrease this felt properly with soda crystals, orange concentrate degreaser and another proprietary degreaser, whilst trying not to destroy it with a Karcher pressure washer!
Thankfully I do my own servicing, so I won't be coating it in anymore oil now!
