wandering temp needle

[passat TS]

[ Converted text/html to text/plain ]

I have two 1.8T cars. So far I've replaced 3 sensors on these cars, one was
under warranty but the other two I had to do it myself. Granted it's a cheap
sensor ($7), but it's a hassle. VAG should recall these things, and put a
decent one.

If you want to replace it yourself let me know, and I'll help you. I have more
experience with this RR than I'd like to...

Welcome to the "sensor" club.
