My Dad's 2012 F10 520D has been making a light buzzing/ticking noise with the engine off and the heater fan turned off. The noise also continues when driving. However it has been intermittent.

What on earth could it be?! Whilst it wasn't loud, it was certainly loud enough to know something wasn't right.

Any suggestions appreciated.
