奥迪A6L C6 2.4L/3.0L汽油泵总成 4F0919051H 动力保障

Your Audi A6L C6 (2.4L/3.0L) showing startup difficulty, sluggish acceleration, sudden stalling while driving, or inaccurate fuel gauge and noisy fuel tank typically indicates the fuel pump assembly aging or wearing, unable to maintain stable fuel pressure. The pump draws fuel from the tank and pressurizes it to deliver to the engine, ensuring sufficient pressure and flow to the fuel injectors for stable power output. Compatible with Audi A6L C6 (2005–2011) 2.4L and 3.0L engines, OEM number 4F0919051H. When installing, be sure to disconnect the battery negative, and keep the fuel pump seal ring and tank interface clean to avoid contaminants entering the fuel system. It is also recommended to replace the fuel filter to ensure unobstructed fuel flow.
