Hey folks,

have a 2007 1.9TDI avant PD engine I believe. Having an issue that I may have been having a while but only recently noticed.

My car whether idle or on a long run doesn’t seem to be hitting 90 degrees on the temp gauge. Just come back from a decent run (150 miles there and back) and the temp didn’t get above about 60 and the fuel economy was really poor, best I got was 38MPG driving steadily in 5th. Only had the car about 2 months and fuel economy was much better previously.

Is this the thermostat that needs replacing? I’m not savvy with cars so will take it to a garage but hoping for a bit of advice so I don’t get ripped off.

The car isn’t running any different, pulls fine in each gear and there are no other issues I’ve noticed.
