I cleaned mine this weekend (Audi A4, B7). The exhaust side was clogged up very badly; I doubt that the valve could open even if it wanted to. Cleaning it made a significant difference to the car's performance, and fuel consumption seems to be better as well.
Read up on Google - it is pretty easy to do. Mine has three consumables - two gaskets and an O-ring - in the assembly. If you can, try to source them beforehand. They're pretty cheap; it should cost you less than R100 to replace all three.
You're imagining the performance gain
