Coolant disappearing

My 2011 Landmark is in the dealer today because the coolant needed topping up twice between annual services (approx 6k miles a year) and then, 2 months after the last service, the light came on again. I booked it in as I've got 2 weeks left of warranty but they're trying to tell me that all cars need topping up from time to time and there's nothing wrong. I just don't buy it given my low mileage and the fact that I had no problems in the first 18 months I owned it. IMHO it must be leaking or I have a faulty sensor. I haven't checked how low it had got because the dealer has been topping it up for free.

Does anyone have any ideas?

It should not need any fluid so the advice, which you probably guessed, is for you to start checking the level so that you know what is really happening.

Some (mine included) do seem to need a bit of a top-up occasionally. Mine's never dropped enough to show a warning, but I do visually check the level when I have the bonnet open for another reason and if it's near the minimum I give it a top-up.

Thanks. I was prepared to live with it but the periods between top ups seem to be shortening. I suspect they'll fob me off tomorrow.

The earlier ones suffer with faulty level sensors. Is the level actually low, or is it just a warning on the dash?

The one place to look for a leak, is the plastic "spider" located in the Vee of the engine which takes the water to the radiator and has one of the bleed pipes on it.

They split down the friction welded seam. Usually it's just a slow process - though mine went in a big way and I lost 10ltrs of water. Being at 8300' made it more interesting!

Well no surprise there - Hatfields deny there is anything wrong. As it's a worsening problem I'm now concerned as to what it will lead to.

I can't see the "spider". There's a plastic air intake in the way so I can't see anything. Is the split on the "spider" obvious even with the air intake in the way?

However, there is a hose/pipe join towards the rear of the drivers side of the engine which is visible when the engine cover is off which is displaying signs of orange fluid leakage. That might be the cause of my leak which sounds identical to the OP.

It's under the engine cover at the front - the bleed pipe is attached to it. You can just see it under the air intake "why" piece.

I'm sure I have a picture somewhere. But it's on advanced factors website.
