Externally vented wastegates (AKA screamer pipes) are illegal.  External wastegates are factory features on the Turbo I5's.  Most turbos seen on cars today have built-in waste gates for boost control, and you can still fit an aftermarket external although, I think technically you need a cert for that...

Yes, externally vented wastegates...

It's been years since I've poked my head under an old Audi bonnet.

Here is a plug in front of the airbox, shouldnt it be plugged into something?
Speaking of the airbox, it has a K&N replacement filter in it.

Here is a pic of the wastegate, does that screw look different?

There is a lot of white polish in all the gaps (wasnt me) which is a PITA to get off.

Is the diverter sound a kind of 'flutter' noise (hard to describe)? I've driven an RS2 with that noise and I don't think it's a big deal... probably just a result of more boost from the chipping, or perhaps a firmer wastegate spring fitted. I'f your lucky it may be a stronger aftermarket valve (factory items are prone to failure).

Does the car have a boost gague? That can be helpful if you are worried about pressure and/or leaks. The fact that the idle is good is encouraging: hopefully there are no inlet leaks.

Do check your tyre size: many RS2 owners make the mistake of fitting 245mm wide tryres, which do not really fit properly on the 7" rims (tyres look kind of wide in the photos). There was once a special tyre to fit these cars, but no longer available AFAIK. I think most RS2s would be on 225s now, or fitted with 8" rims.

Car looks way better in the pics than I expected! Replacement buttons and so on should be easy to source as they are common across most of the 90s Audi range.

Its a flutter noise, can make it as early as 2,300rpm, Dads car seemed to make a noise around 3,500rpm.

The car has no boost gauge and the intake pipes dont have factory clips holding them on which leads me to believe that they have been replaced once at least.

Tyre wise I remember the issues these cars have, the Dunlop 8000 that was designed for the car wasnt a true 245/40/17, my car is currently fitted with a 235/45/17. They seem way to big and are very close to rubbing on some suspension componates in the rear. Ill replace those with 225/40/17s (not a hard tyre to find). What are other RS2 owners using tyre wise?

The top vacuum pipe off the wastegate cap is missing, or do they not have one?? Not sure about the bolt like thing going in also, are they not sealed off there??

Usually you see a recessed allen key type arrangement. Homemade wastegate adjuster?...may be part of the equation for the 'flutter' noise.

Boy, you're going to have a whole heap of learning with this puppy  ;D

Nope - that vacuum connection off the wastegate should not have a pipe off it - not used in the RS2.

Yep - the wastegate screw looks odd - there should be a recess with an alen-key to wind it down (from the factory that is covered with some sort of gunk to stop you fiddling with it).

The flutter noise is (I think) the wastegate acctuator flicking the gate open to control boost.

Not sure what that connector is - will take a look.

I would guess that someone has been messing with boost control, but no idea exactly what's been done. You could measure manifold pressure while driving to see what kind of boost it's making, then try to work out what's been done.
