I know a pic would be useful here but there seems to be some kind of valve thing attached to the back box of my S3 with a rubber pipe going somewhere. What's this for and if I plonk for a catback Milltek system, does it come with the same valve?
all it does is the faster you go the more the valve opens giving you a louder exhaust note... and no you don't get that with a milltek.... that just always loud haha

Is it only S3 that have this? Or does my 2.0TFSI have it too.
Will have to go under and check.
If I dont have it does anyone hav a S3 back box for sale with the valve intact?
There is the same valve on the a3 3.2 v6 and there are some threads on here about removing the long pin that goes through the valve and using steel wire to tie the valve open.
Long pin with 90deg bend to be removed from hole
Long pin removed and now the valve is ready to be tied open with steel wire.
Hopefully this will not cause any alarms as the actuator valve is still connected to the vaccum pipe.
