Audi S 3 8 P Engine Bay. Audi dealer will know what to do with it. but your APR tuned. so let us know how that goes. Having scanned the factory engine bay, a one-piece design was created to eliminate jagged edges and unnecessary couplers within the intake tract.
It's some sort of a membrane valve within (?) the engine (not a diverter valve) that goes bad and start making this crazy honking / whistling noise. We discuss some of the issues with this car so you can decide if its worth buying. APR develops and manufactures hardware, software, calibration & data-logging tools for engine and transmission controllers, including intakes, exhaust systems, intercoolers, turbocharger systems, suspension, brake systems, wheels, and more.

Some time ago I noticed a strange sound coming form engine bay it was quiet on start but now its really irritating. General Information about this Model can be found in the Wikipedia entry. I went to the dealer for a diagnose and they told me that my gasket form vacuum pump is gone and some oil leaked on my gearbox.
