ETKA is ambiguous in this regard, as it shows the following:

- Thermal switch (aka Temp 2 gauge), two part numbers: 251 919 369 and 025
906 041A. The 369 part has a "Qty" of X, and the 041A part has a Qty of 1.
Anyone know: does X mean the part has been superceded?

- Temp sensor for coolant temp gauge: 251 919 501 (black, Qty X) and 251
919 501D (green/black, Qty 1).

This page might be helpful for you, as it has pix of all these parts:
