After shutting off my '07 MCS, I hear this coming from the right passenger rear. I may hear it while driving, but it's drowned out by other noise, and that might have been my imagination.

I have had some problems with the boot -- I can't shut it unless I unlock it again, and today it did want to open itself a few times while parked...

Anyone know what this is?

 

Oops, wrong forum -- this is 1st gen, I'll move it over.
