Sender and gauge have to have matched properties.  I would expect
sender and gauge typically to come from same mfr for best results,
but mfr may have different lines of gauges/senders with different
properties, and the senders for different temperature ranges will be different.

The info on the forum you pointed to is highly specific to OEM VW oil
temp gauges made by VDO, and the senders they're talking about are
specific senders for specific versions of the VW oil temp gauge used
on a particular range of vehicles (maybe more as well).  If you take
a gauge and sender out of the same vehicle at the wrecker's yard they
will match.
