The Audi K03 Turbocharger (OEM 078145703L) is a used genuine turbo removed from a salvage donor. This left-side unit forces compressed air into the 2.7L V6 turbo (2671cc) engine, common in Audi S4 and Allroad models. Typical failure symptoms include oil leaks, shaft play, or loss of boost pressure. It replaces numbers 078145701L, 078145701H, 078145701B, 078145703H, 078145701S, 078145701R, 078145703S, 078145703R, and 078145701SX. If you hear whining or see smoke, this direct swap restores factory boost delivery.
