Setup, Compatibility & Care
Before installation, ensure the engine and exhaust system are completely cool to prevent burns. Always clean the mating surfaces of both exhaust flanges thoroughly using a wire brush to remove carbon deposits or old gasket material, as debris can prevent a proper seal. When tightening, use a torque wrench to apply manufacturer-specified pressure in a cross-pattern to avoid warping the flange. Compatibility is limited to specific VAG group engine configurations; always reference your vehicle service manual or the part number 110-966 to confirm your model year and engine code match the specifications.
