Hi. 2011 Countryman, bought new from the dealer. We’ve had it for a year and a half. Premium sound system has audible hiss when the radio is turned off. Also when the car is turned off. Also when you unlock the car, get in, shut the door, but don’t put the key fob into the slot.
Note that the RADIO IS NOT TURNED ON. The CAR IS NOT TURNED ON. But there is still an audible hiss in all speakers, front and back. I’m 60 years old: if my aged ears can hear the hiss, it is probably not subtle.
Clearly the power amplifier is powered on when the remote unlocks the doors. Possibly also when the doors are opened. Also after the car is turned off – even if the key fob has already been removed from the slot.
We have taken the car to the dealer multiple times to resolve this. Hiss remains. Dealer says this is a known design flaw, that Mini knows of the problem, and is “working on a solution.” Hm. No solution in over 6 months. Hiss still pronounced and present. I guess Mini is not working very hard on the problem.
Seems to me that a “premium sound system” should not have audible hiss at any time. Especially when it is NOT TURNED ON.
Am I the only owner with this problem? Does your Mini’s premium sound system hiss when it is turned off?
