A used genuine OEM Audi window regulator, OEM part number 4B0839398B, also replaces 4B0839462. This rear right (passenger-side) unit operates the power window glass up and down. Common failures include slow movement, grinding noises, or the window dropping off track. It fits Audi A6, A6 Quattro, Allroad, RS6, and S6 models with 2.7L turbo V6, 2.8L V6, 3.0L V6, and 4.2L V8 engines.
A bad window regulator can cause your window to lift up crooked and jam. This will stop your window from lifting all the way up. This also will cause more wear on your window motor.
