Correct hardware selection supports proper positioning, while the separate pump seal provides sealing at its mating surface.\u003c\/p\u003e\u003cp\u003eThe same model and engine displacement can have different vacuum-pump fasteners. For the listed GTI application, earlier CBFA production and CCTA engines use different hardware. Confirm the original screw number, engine code and build date before ordering.\u003c\/p\u003e\u003ch3\u003eCommon reasons to replace\u003c\/h3\u003e\u003cp\u003eReplacement may be required during vacuum pump removal or replacement when the factory procedure calls for new mounting hardware. Replace damaged threads, a damaged internal drive recess, deformation, missing hardware or corrosion affecting reliable installation.\u003c\/p\u003e\u003cp\u003eVacuum-pump sealing work can reveal damaged screws or incorrect substitutes left by earlier repairs. Inspect the mounting connection and obtain the correct fasteners and separately required seal before reassembly.\u003c\/p\u003e\u003cp\u003eOil seepage near the pump, vacuum-related faults or reduced brake assistance require diagnosis of the complete pump, sealing interface, hoses and associated system. A new retaining screw cannot repair an internally defective pump, damaged seal, leaking vacuum line or compromised mounting thread. Correct the diagnosed issue before completing the attachment.\u003c\/p\u003e\u003ch3\u003eInstallation and service notes\u003c\/h3\u003e\u003cp\u003eFollow the factory vacuum-pump procedure for the exact CBFA arrangement. Prepare the engine and disconnect associated hoses or components as prescribed. Keep dirt and loose hardware away from the exposed pump interface and oil passages.\u003c\/p\u003e\u003cp\u003eIdentify the assigned N10739401 positions and inspect the mounting surfaces and threaded holes. Use the correct new seal wherever the procedure calls for replacement. Position the pump according to the repair instructions rather than forcing it into place with the mounting screws.\u003c\/p\u003e\u003cp\u003eStart each screw by hand in undamaged threads. Use a fully seated bit that matches the internal drive recess, and tighten the complete connection in the prescribed sequence so the pump seats normally.\u003c\/p\u003e\u003cp\u003eApply the factory torque and any additional angle for this exact attachment, together with the required thread preparation and hardware replacement rules. Do not infer torque from M6 or transfer a value from the earlier pump screw.\u003c\/p\u003e\u003cp\u003eReconnect the original vacuum hoses and components, then perform the required sealing, vacuum-system and operating checks after assembly. Confirm proper brake assistance according to the prescribed service checks before returning the vehicle to use.\u003c\/p\u003e\u003cp\u003eThis listing supplies one original retaining screw.
