It sounds like a feature that doesn't actually do anything. It's common for salespeople to not know about every little detail. It could be a software error or a feature that was never fully finished. Since it only seems to work in Sport mode and you can't hear any difference it probably isn't working right. You should contact DS customer service for answer, or just accept that it's a software bug.
