I'm an idiot anyway, you know this, so I don't know much about what to
look out for or where to look. :) I'm getting there slowly though, I've
only had an Audi in my hands for 3 months now and have learnt a lot
about
to fix things on it. Now I'm on to watching lines into and out of the
turbo. I'll need to find a South African supplier of steel braided
hoses.
Who manufacturers the best braided lines? Are they online?

> Where is it coming from?

Hard to tell. It can heard if I stick my head under the front right of
the
car (ie. turbo side of RHD vehicle), but this is the intermittent
"cricket"
in the works sound. The whistle I hear while driving, but this I'll only
hear on my side of the car (driver's side & turbo side). It isn't a
constant
pitch whistle, it sometimes drops a bit and then jumps up again. Goes
away
from slowing down. It can't be body-whistle as the panels haven't been
smashes/adjusted (??) since I got the car and it has only been happening
for
the last month. Also, there was a real loud ruined bearing sound coming
from
the same side of the car, eventually had the alternator recon'd which
eliminated that noise, but then the whistle popped up. I do know that
that
entire side of the car is oil coated now, including the alternator,
which 
is now in the same oil coated state it was when I took it in to be
recon'd.
Another thing about the whistle is that about a month ago it was
extremely
load, but only after cold start in the mornings, but we're talking a
"everybody turn and stare at whistle Boeing" type of sound. That doesn't
happen anymore and the whistle has moved on to higher speed travelling.
I
have asked the guy who has the car today to try and find it, but I don't
think he'll narrow it down. At least he'll probably give me a area from
which
it is coming and then I'll let you know.

No, it is not the buzzing sound. As I said, it seems to be coming from
an
area around the turbo, but can pin-point if it is the turbo or something
else. The buzz I'm used to, actually makes for interesting conversation
when talking to someone with the hood open and the engine running, they
even take a step back when the fan comes on as well (esp. with the motor
off :), damned Toyota Corolla drivers!!! :))
