Staz, as per this thread:
http://www.audi-sport.net/vb/showthread.php?t=82565 , which you also replied to, I am still trying to work out why my exhaust has gone as quiet as it has gone now.
I logged it again, and I found that the waste gate duty cycle had changed a bit. I suspected a leak, and lo and behold, I found that a silicon pipe going to the Forge DV was torn.
This however did not sort out the issue on the sound of the car.
Another way to explain what the car is doing, is that there is a lack of back pressure in the system. I do not have that "gush" out of the exhaust anymore.
Hence, I was wondering how that solenoid works i.e when it is open/closed ? What activates the solenoid, etc.
Thanks
