Car Parts Catalog - LLLParts 2nd line down on that page, 6R0 825 237D is the only engine undercover I would expect to find on your car, I think, but message me the VIN if you wish me to check properly. Your service list contains a lot of items that should be deleted, complete waste of time and money, items 1, 2, 9, 10, 11, 13. Seriously; all of those are more likely to cause a problem if touched than to offer any benefit. A good mechanic should probably refuse to do most of these, knowing the waste of their time and your money. 9 and 11 might be worth doing in about 100k miles' time. Item 8 is also probably unnecessary but less likely to cause a problem, although a vacuum/pressure refill is recommended on the rather complex cooling system of these engines. Air pockets can remain and take time to work their way out otherwise, I understand. I don't have experience of using such equipment. Buy a genuine oil filter from Skoda, and make sure your mechanic doesn't leave behind the old seal when changing it; bad things happen to oil pressure and engines which suffer this accident.
