I'd get a used one. What is the current unit on the car? Appears the repair part in the catalog is 81A 955 547 B, previously 8U0 955 559 C, previously 8U0 955 559 B. Looks like it would be 8U0...B on the car if the original is still on it.

A new one would include the gel foil, but you'll need to get a new one for a used unit. 8U0 955 609.
