[Biturbos4] scraping, squeeling noises

Hi Bob,
I drove it around town a little more today and apparently the offending
debris dislodged itself.  The noise has disappeared.  I'll ask the
dealer to check it when I take it in for the 30k service.  There is a
cover over the inside of the disk that could probably trap the right
size hunk of gravel.  I pulled it onto the Rhino ramps and pulled out
more dried mud from up under the wheel well and elsewhere underneath.  I
suspect the right sized pebble dropped in there and just took a while to
break up and be ejected.  Braking seems fine as usual with no pulling,
so I think its OK.

Are you in Colorado?  It would be fun to meet some of my fellow S4
owners to the south.  Not a lot of Audis in WY, let alone S models.
There's an S6 here in Laramie and a sprinkling of A models.  Thanks for
the note.

The local Subaru dealer has one of the WRX STIs on the lot.  It looks
like fun, but I don't care for the looks.  The exaggerated hood scoop
and outrageous rear wing are a bit much.  Not nearly as classy as our

And I'm impressed with the toughness of the S4, especially after being
towed out of the mud by the rear tow point by a big diesel Ford F350.  I
was very concerned that something would give as it took multiple runs at
it to finally jerk it up off the muddy side of the road.  So far there
doesn't seem to be any significant damage, just a lot of muck
everywhere.  I'm not sure the lighter Japanese models would stand up
like the Audi.  Between this incident and hitting a couple deer I would
say these Audis are substantial and well built machines.

Having said that, I don't recommend trying any of these things yourself.
I've been lucky to just scare the crap out of myself and have to walk
for help.  Be careful out there.  Cheers.

I was on some snowy roads in Colorado a couple of weeks ago and got the
noise.  I tried backing up and braking, which must have dislodged
piece of gravel was caught in there.  Also, after power-washing the
wells when I got home, I got the same awful noise until I cleared it the
same way.  Everything's fine since then.  When I took the snows off,
everything looked OK.  The S4 brakes must be very susceptible to picking
