The Audi lower door cover, also known as a cap or plug (OEM 8N0831439), is a genuine used trim piece from a donor vehicle. This small plastic cover fits the lower door area on first-generation Audi TT and TT Quattro models, regardless of engine—whether the 1.8L turbo or the 3.2L V6. Its job is to seal the door’s lower access hole, protecting against moisture and debris.
