FAQs – Fuel Injector Leak-Off Hose (04L130235B) What does an injector leak-off hose do? It carries excess diesel from the injectors back to the fuel return line. Diesel engines always send a small amount of fuel back this way, so the hose must stay sealed. What are the signs of a leaking leak-off hose? Strong diesel smell in the engine bay or cabin Wet or oily residue around the injectors Hard or slow starting, especially after the car has been parked Cracked, brittle or loose connectors on the old hose Which engines does it fit? It is for common rail 1.6 TDI and 2.0 TDI engines in the VW, Audi, SEAT and Skoda models listed in the compatibility section. It does not fit petrol engines. Is 04L130235T the same as 04L130235B? 04L130235T is listed as a cross-reference for this hose. Part numbers can change between production years, so always compare the number on your old hose or contact us with your VIN or registration before ordering.
