Hi guys,
I own 1.9tdi bought new in December 2008, with around 60k miles on the clock, mostly highway. Last two years I did around 5k, mostly city driving (cause I now work from home and don't travel as much), and I've noticed one strange issue lately.
Gauge for temperature was always pinned to 90 degrees (vertically) after engine gets warm, and wouldn't move much, but lately, it gets stuck just a millimeter before 90 degrees, stays there, then falls a little bit (maybe a mm or so), then comes back again almost covering the 90 line, but not completely and then drops again.... sometimes it does climb correctly and stays on 90, but there's much more irregularity then before.
I've also noticed 3 weeks ago when I did 300 mile trip on the highway, gauge was at 90 and then slipped a bit all of a sudden.
My impression is that thermostat is probably becoming faulty. What's the risk of it getting stuck in closed position? Should I change it immediately? Or could it be some other problem, like sensor or something.
Thanks.
