Cabin sounds like water from a dripping tap

Hi MG3 Hybrid owners.
After 940 enjoyable miles, I have encountered a new sound much different from the chirps and bongs I'm getting accustomed to, this is somewhat akin to that of a single water drop falling from a water valve in a header tank. The single drip sound occurs quite regularly with a few minutes between. Although faint it becomes more obvious when driving slowly and the cabin is quiet. I wonder if it has something to do with the air conditioning or the water circulating in the heating system. Has anyone else noted something like this?

I haven't come across anything like this myself, do you hear this noise when stationary and the engine off, or does it just occur while driving?

Hi Clive.
At the moment I've only noticed it when I'm driving the car around town. I'm going to keep my eye on it to note any changes (and keep an eye out for water). It's one of those not-noticeable noises until I pointed it out to my wife, now she hears it like I do!

Whilst completely unconnected, I get a creaking from the dashboard when the heater is on. It would suggest plastic expanding as parts of the dash get warm.
