Audi side view mirror housing trim, OEM part number 4A0858523, is a genuine used part from a salvaged vehicle. This left-side trim piece covers the mirror housing's exterior, protecting internal components from debris and weather. It is also known as a mirror cap or cover. The trim fits multiple Audi models from the 1990s, including the 100, A4, A6, A8, and S4/S6, across various turbocharged and naturally aspirated engines. When this trim is missing or damaged, wind noise or water intrusion into the mirror assembly can occur.
