This used OEM Audi trunk release switch (part number 8K0959831A) activates the trunk lid from the driver's cabin. Also known as the trunk release button, it's a direct replacement for the original unit. When this switch fails, the trunk may not open unless you use the key fob or the external release. It was removed from a donor vehicle and fits multiple Audi models equipped with a variety of engines, including the 1.8T, 2.0T, 3.0 TDI, 3.0 supercharged, 3.2L, and 4.2L V8.
