Losing Coolant slowly

Hey everyone,

So I recently purchased a 2015 Touareg TDI and have noticed that it's losing coolant. Every few days I'm having to add coolant but not a whole lot. It gets just below the minimum line and so I add more. I've added 3-4 times now since purchasing 3 weeks ago. The temp while driving never gets above 200-205 even during long trips so no overheating issues yet.

Where could this slow leak be coming from? EGR? Oil cooler? Water pump (I would assume I'd lose more if it was the water pump). Also would these issues be covered by the extended emissions fix warranty? Just wondering whether I should bring it to a VW dealer or to a good locally known VW mechanic.

Is there something I could look for myself? Are any of these issues easy enough fixes or just best to take it to a dealer?

savagesoot is right. its the oil cooler. I've had mine replaced twice now. first time the dealer did it and it failed 1,000 miles past the warranty. second time went to the indy shop so far so good.
