This is the second thermostat related post I've seen. Did you also post the first?
I made the other thermostat post. It took until THIS week for the part to come in and I just had the thermostat replaced Monday. The dealer said that the manufacturer told them this problem has been coming up elsewhere and instructed them to return the thermostat to them so that they can determine what is going wrong.This is the second thermostat related post I've seen.

I have wondered about that because the operating range on the gauge is very small (solid bar part) and makes it very difficult to discern between 70C and 90C which would be where normal operating temp would usually be.I made the other thermostat post.

Kind of sucks to see someone else having the same issue but at least this will help determine what the issue is and hopefully it won't keep happening. Has this new part fixed the issue for you by chance?I made the other thermostat post. It took until THIS week for the part to come in and I just had the thermostat replaced Monday.

That's true as it took 1500 miles for mine to start failing. Today is a little warmer outside and the CEL went away and hasnt come back up today.So far it seems okay. But the original took a couple of weeks before it started failing.
That is good news. I am waiting for a thermostat after having gone to the dealer for a CEL. On my first trip they did a flash update which took out the CEL, but my slow warm up continued. The tech thought it was probably normal. In a week the CEL came back on. I reported this by phone; "we are still waiting for the thermostat." The next week the CEL went off and has stayed off, but the blue light typically needs 10 minutes and five miles to expire, and full temperature doesn't come until 20 minutes and 10 miles have passed. Too long. I am glad to hear that the new thermostat has made more of a difference than just extinguishing the CEL.Had the thermostat code at about 850 miles. Dealer ordered new one and said it was ok to drive until part came in, which took about a week. Replaced thermostat. I have noticed that the blue light goes out sooner than it did before the thermostat was replaced. Also seems to get to operating temp sooner.
I think the best test is to watch how long it takes for the engine to come up to operating temp (when the needle moves to just beneath 200°). Mine is taking twice as long as the two diesel-engined cars I own, both of which have a lot more cold iron to warm up (albeit higher combustion temperatures). I think 20-30 minutes in 40° is too long to run the little Fiat cold.The tech stated that they "tested" the thermostat and found it worked properly. They then kept the car so they could drive it in the morning to see if it would happen again. Didn't happen. I am keeping a watch on the thermostat to see what happens the next couple of weeks.
It shouldn't take more than 5 minutes. I haven't timed it, but I know how long it takes to get to the grocery store, and the light is always off before I get there.I think the best test is to watch how long it takes for the engine to come up to operating temp (when the needle moves to just beneath 200°).

Did they remove the thermostat to test it? I think it would be silly for them to go through the trouble of removing it and not outright replacing it. This makes me wonder what they did to "test" it. It makes sense to me to just replace the thermostat under these circumstances. I can't stand dealer service centers sometimes.The tech stated that they "tested" the thermostat and found it worked properly.
