A used genuine Audi master window switch / button, OEM part number 4E0959851B. This left-hand switch controls all windows from the driver's position in A8 Quattro and S8 models with 4.2L V8, 5.2L V10, or 6.0L W12 engines. When the master switch fails, individual windows often stop responding from the driver's door or function intermittently. Also known as a window button, this OEM unit is a direct replacement.
