Ticking noise behind instrument cluster

I recently purchased a 2025 A6 Allroad and noticed that a ticking/clicking sound appears when reaching 60mph. If the radio is on you can't hear it but it is noticeable if you aren't hearing music or the radio. The dealer says this is normal and may be due to the vacuum pump which seems very odd to meand I'm not happy with this response so I have to live with it. Has anyone encounterd this problem on their A6?
