Peugeot 3008 Coolant Loss

Hey, I also drive a 3008 (older model). I had something similar happen. The check engine light was on, and the codes pointed to the coolant. Have you checked for visible leaks under the car when parked? Do you notice a sweet smell after driving?

I inspected under the car and didn't see anything. I haven't noticed any smell either. Anything else I should look for, or that you experienced?

If you're not seeing leaks or smelling anything, it might be a small, slow leak. Given the codes and coolant disappearing, I'd recommend a workshop. Better to get it checked before it causes serious damage.

I took it to a workshop, as you advised. It turned out to be a small leak in a hose, which was replaced. The total cost was 52€.
