I am looking to enquire about a throttle body/Intake Manifold Flap for my audi a4 2.0 170, BRD engine code. The car is 2006 reg. The car is lacking some power and is revving at irregular levels when idle and I have noticed that the problem might be attributed to a broken component of the control flap, maybe a broken seal or a gear inside. (Picture) It would be much appreciated if you could get back to me as soon as possible with the price and delivery details. Thank You
