re. UrQ grinding and crackling noises, and electrical smell upon boost

[Ben Swann]

For 2 & 3..Check for rodent nest in the intake to the ventilation system
(aka appropriately named "suirrel cage").

It seems rodents of sorts, incl. mice and squirrels have developed a
genetic predisposition to homing in to this area of these cars to build
their winter nests when left parked outside for any duration.

[Last week I checked out an UrQ for sale in the area.

A few issues that I noted:

1)  There is a grinding/rattling noise coming from the rear of the car when
it
is moving, it goes away when stopped.  It sounds kind of like a diesel
engine.
Rear diff?  Wheel bearing?  It doesn't get louder or higher in pitch as
speed
increases though, just goes away when stopped.

2)  With the car running and when moving or not, there is a crackling noise
coming from under the drivers front speaker.  What could cause this, it
didn't
go away when I turned off the fan, though it sounds like the fan is
stirring up
some debris or something.

3)  While test driving on the highway, when I floored the accelerator and
the
turbo built boost, an electrical burning smell entered the cabin.  This
only
happened once.  I tried to replicate the problem to no avail.

The car seems to be very well sorted, and I'd like to buy it, but I need to
resolve these issues before I buy.

Any input?

TIA,
