Hi maria

With such a small amount of loss, you won't see any visible leaks without a very close inspection. Expect to find a pinprick of a leak that may only show up when the engine is hot. If could be from the radiator or behind the engine. Because it may only happen when hot, this makes it very dangerous to search for.

Other than that, it could be the head gasket, what colour is the coolant?

Head gasket failure is not so common on the diesel.

Hi Arfur,i have looked and the colour is amber and a smooth feel to it.I bought the car about 5 weeks ago,with 53.000 miles it has a full Citroen mean dealer history and was last serviced at 48.000 and is know at 54.000. and drives A1 apart from the coolant loss.

Hi Maria, I just wondered if you did resolve that coolant leak? I also have a 2015 C3 with a small coolant leak and haven't found it's source yet.

I would be pleased to know so I can look in the same area.
