Most likely a dealer-only item, P/N is 078 103 175 D.

Default I bought mine at a VW dealership, was less expensive.
Also are you talking about the ones under the valley pan or in the head?

The ones in the heads are oil pressure relief valves, not check valves.

Default Check valves prevent back flow of the oil, keeping oil in the head oil system....
The relief valves prevent excessive oil pressure from developing in the head oil system.
