VAG: Outside temp gauge messing with my climate control?

[Andrew Duane]

Yes, that's the way it works. Luckily, the fix is either trivial or easy
depending on what is wrong.

The front grill outside temp sender sits on a little bracket held in
front of the air intake for the radiator. Often times, due to road salt
and much, the connect gets corroded. Look for green schmutz around the
connector. If it's there, pull the sender off, open a beer and spend 5
minutes alternating sips with steel wool or fine sandpaper rubs to clean
it up. If no schmutz, you may need a new sender, but they are not that
expensive, and easy to replace (just plug in).
