I bought at $18, "BOS 0280-130026 EUR84-88 TEMP-SEN" from Halsey Import
Parts Distributing,  Portland, OR 1-800-792-0081.

Halsey is the best quality, and priced, VW vendor I have used.

Why do so many VW vendors sell low bid junk parts?

Beware if you buy from these low bid parts vendors that sell junk:

1. Chequered Flag Import Parts, Beaverton, OR.

2. Bow Wow Auto Parts, Boise, ID.
