Peugeot 107 Coolant Loss

Alright Peugeot gurus, I'm racking my brain here. My 2011 Peugeot 107 diesel is acting up. Coolant level keeps dropping, triggering the check engine light and storing an error code. I've checked for obvious leaks around the water pump, radiator hoses, and even peered at the expansion tank, but nada. Could it be air pockets, or am I facing something nastier like a head gasket issue? Mileage is at 183506 km. Anyone else experienced this?

I had something similar happen with my 107. Is your cooling fan running properly? I noticed mine was intermittent, and that seemed to be contributing to coolant loss. Have you checked for any white smoke coming from the exhaust?

Interesting! The cooling fan seems to kick in when it should, but I haven't paid super close attention to it. And no, haven't seen any white smoke... yet. Was your coolant loss gradual or sudden before you clocked the fan issue?

My coolant loss was pretty gradual at first, a little top-up every week or so. But yes, it got much worse when I noticed the fan acting up. Better to find out what's up and go to the workshop before it gets worse! Hope it all works out!

Cheers, that intermittent fan thing is food for thought. I booked it into a workshop, and turns out it was a leaky thermostat housing; thankfully just a 52€ fix! Thanks for pointing me in the right direction!
