I recently hooked my 2005 Audi A3 to VCDS after the engine management light came on and got the reading:
Motor for Intake Manifold Flap (V157): Open or Short to Ground
I have seen various images on forums where people have taken off what appears to be a box containing cogs which have worn away resulting in the same error code. I am looking to locate this myself and check the flap is opening and closing.
My first question is, where can i find the 'flap' and secondly where can i find the motor that controls the 'flap' to check the teeth on the cogs have not worn away? Any help is appreciated. I have attached an image of my engine. Hope this helps.
