Damaged connector retention, a split bend or an insecure end fitting can allow air to escape instead of reaching the intended secondary-air passage.\u003c\/p\u003e\u003cp\u003eSecondary-air faults require diagnosis of the complete system. A damaged hose is one possible cause of insufficient flow, but a failed pump, valve fault, electrical problem or blocked passage may produce similar symptoms. Replace this hose when inspection or testing confirms damage; a new hose does not repair another failed component.\u003c\/p\u003e\u003ch3\u003eInstallation and service notes\u003c\/h3\u003e\u003cp\u003eWork with the engine cool and follow the applicable access procedure. Release the original connectors carefully, support the adjacent pipe and avoid twisting aged plastic fittings. Inspect the mating connections, seals and nearby hose sections before fitting the replacement.\u003c\/p\u003e\u003cp\u003eRoute the hose as originally installed, fully engage its connectors and retain the prescribed supports. Check that it cannot rub against moving components or contact hot exhaust parts. After service, verify connector security and evaluate secondary-air operation using the appropriate diagnostic procedure.\u003c\/p\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eVehicle\u003c\/th\u003e\n\u003cth\u003eModel years\u003c\/th\u003e\n\u003cth\u003eEngine\u003c\/th\u003e\n\u003cth\u003eBody and transmission\u003c\/th\u003e\n\u003cth\u003eRestrictions\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eAudi TT\u003c\/td\u003e\n\u003ctd\u003e2003–2006\u003c\/td\u003e\n\u003ctd\u003e1.8L turbo gasoline, 180 hp\u003c\/td\u003e\n\u003ctd\u003e8N coupe; Manual transmission.\u003c\/td\u003e\n\u003ctd\u003eSecondary-air outlet hose to the control\/combi-valve connection; not the 225 hp or automatic-transmission hose.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAudi TT\u003c\/td\u003e\n\u003ctd\u003e2005\u003c\/td\u003e\n\u003ctd\u003e1.8L turbo gasoline, 180 hp\u003c\/td\u003e\n\u003ctd\u003e8N roadster; Manual transmission.\u003c\/td\u003e\n\u003ctd\u003eMatch the 180 hp manual secondary-air hose; 8L0-133-817-A is separately cataloged for the automatic application.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVolkswagen GTI\u003c\/td\u003e\n\u003ctd\u003e2005\u003c\/td\u003e\n\u003ctd\u003e1.8L turbo gasoline\u003c\/td\u003e\n\u003ctd\u003eMk4 hatchback; Match original secondary-air plumbing.\u003c\/td\u003e\n\u003ctd\u003eCatalog specifies from VIN 1JY490001; match the original hose and adjacent connecting pipe.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVolkswagen Jetta\u003c\/td\u003e\n\u003ctd\u003e2005\u003c\/td\u003e\n\u003ctd\u003e1.8L turbo gasoline\u003c\/td\u003e\n\u003ctd\u003eGL, Mk4 sedan; Manual transmission.\u003c\/td\u003e\n\u003ctd\u003eAir-pump-to-control-valve outlet connection; retain the original Mk4 hose arrangement.
