The fuel pump module in the Audi A4L is located under the rear seat on the right side. Open the cover above the fuel pump under the seat. Introduction to the fuel pump: The fuel pump is a lightweight and compact pump, which can be categorized into inline, distributor, and unit types. The fuel pump requires a power source to operate, and its lower camshaft is driven by the engine crankshaft gear. Steps to replace the automotive fuel pump: First, pry off the fuel pump cover; disconnect the wiring harness plug; remove the two fuel lines; take off the sealing ring; remove the fuel pump assembly; detach the fuel float rod; remove the fuel pump chamber cover; detach the two lines of the fuel pump chamber cover; remove the fuel level sensor PCB board; detach the fuel float rod linkage arm; pull out the fuel pump core; remove and clean the fuel filter screen; check if the sensor contacts are functioning properly; install the new fuel pump and reassemble all the removed parts in order; start the engine and check the fuel gauge's working condition.

What is the name of the curved panel above the wheel?

The curved panel above the wheel is called a wheel arch cover. The main purpose of the wheel arch cover is to prevent mud from splashing onto the car body or pedestrians during rainy days, which could make them look unattractive. It also helps prevent mud from splashing onto the tie rods or ball joints, which could cause premature rusting. Another function is to prevent road mud from being thrown onto the car body and damaging the exterior paint. Wheel arch covers are typically made of high-quality rubber or engineering plastic. They are usually installed as a shield behind the wheels of bicycles or motor vehicles. The wheel arch cover protrudes about 5 centimeters from the car body to effectively prevent flying stones and gravel from damaging the car's paint surface.

Does coasting in gear with electronic fuel injection save fuel?

Coasting in gear with electronic fuel injection does save fuel. Here are some commonly used fuel-saving driving techniques: 1. When starting: The starting quality of the engine before the vehicle moves off directly affects fuel consumption. The more times you start, the more fuel is wasted. When starting the vehicle, choose a low gear, apply the throttle smoothly, and accelerate gradually. When the car reaches a certain speed for a gear, learn to listen to the engine sound to shift up progressively from low to high gears. 2. While driving: The car should be driven at medium speed in direct gear to save fuel. The economical speed for most cars is between 65 and 90 km/h.

How Often Should the 7-Speed DSG Transmission Fluid Be Changed?

7-speed DSG transmission fluid is recommended to be changed every 70,000 to 80,000 kilometers. Below is an introduction to the 7-speed DSG transmission: 1. Features: The "dual clutch" is installed in a sealed oil chamber. The dry friction discs on the moving plate can indeed provide the most direct transmission efficiency, but they are also more prone to heating up. Therefore, their heat resistance is not as good as that of wet clutches, and consequently, they can withstand relatively less torque. 2. Working Principle: The dual clutch consists of three similarly sized clutch discs installed coaxially in a stacked arrangement. The two clutch discs on either side are connected to gears 1, 3, 5, 7 and gears 2, 4, 6, reverse respectively. The middle disc moves between them, engaging or disengaging with the two clutch discs to perform gear shifts.

What Causes Water Dripping Behind the Car Trunk?

Water dripping behind the car trunk is caused by: 1. Wear and aging of the trunk seal or trunk deformation; 2. Drain pipe blockage leading to water leakage. Since the trunk is not completely sealed, some sand and mud may enter the drain pipe during rain or car washing. The drain holes are designed to be very small and can easily be clogged by dust or mud. Solutions for water dripping behind the car trunk: 1. Remove the rubber plug at the bottom of the spare tire compartment in the trunk to allow drainage; 2. Locate the leak by checking if the trunk lid is deformed or if the surrounding seals are aged. Use a hose to spray water and observe where water enters, or close the trunk lid after water enters and mark any spots where light shines through.
