Avventura diesel temperature issues
Summary of the thread
A 2015 Fiat Avventura diesel is experiencing dashboard temperature fluctuations, a persistent check engine light, and delayed engine warming. The initial suspicion was a blocked cooling grille, but the coolant level was confirmed to be fine. Suggestions included checking for grille restrictions and considering electrical issues, such as a faulty thermostat or temperature sensor. Ultimately, the problem was identified as a defective fuse related to the cooling system, which was resolved at a workshop.

No overheating yet, but I'm worried it's heading that way. The temperature gauge seems all over the place. What was your issue, and how did you narrow it down? Was it the grille itself, or something electrical? Did the check engine light also come on?

Yeah, the check engine light was on for me as well. I initially suspected the grille but it turned out that the thermostat was busted and the temperature sensor was sending bogus data to the ECU. I suggest you take it to a workshop.

Right, I see. Sounds like it's beyond my skills. Thanks for the tip, I'll get it booked in! Just got it back from the shop. It was a defective fuse linked to the cooling system causing the temperature sensor to act up. 52€ all in. Thanks for the help!

Sounds familiar. I have an Avventura too, and I had similar symptoms a while back. Check if your cooling grille is actually restricted or if it’s something else fooling the sensors. Has the car been running hot or overheating?
