The Fuel Pump inside the Audi A4

Location and Purpose of the Fuel Pump Relay on a 2002 Audi A4
the fuel pump relay on a 2002 Audi A4 is behind the fuse box under the steering wheel, marked with 167.
In today’s cars, the fuel pump is usually electric, and the pump creates pressure in the fuel lines by pushing the gasoline into the engine. In most cars, the fuel pump delivers a consistent flow of gasoline to the engine and unused fuel is returned to the tank.
Fuel-injected cars have an electronic control unit that prevents fuel leaking from any ruptured fuel line.

Operating Your Car: Tips To Keep Your Car Longer Life 1/6

1. Be patient during the break-in period

You’ve bought your dream car and now you want to make it last at long as possible in top condition. Here are some things to remember as you pull it out of the dealer’s lot:

During the break-in period, typically the first 1,000 miles (1,600 km), keep your speed under 55 mph (88 kpm) or to the speed recommended by your car’s manufacturer.

Avoid heavy loads on the drive train, such as towing trailers, and loading the roof rack or trunk with heavy construction materials.

Do not allow your new car to idle for long periods — this is good advice for the life of your car, but especially during breakin. The oil pressure generated by doing so may not be sending oil to every part of your engine.

Use only light to medium acceleration, keeping the engine rpms below 3,000 for the first few hours of driving.

Car Interior: Tips To Keep Your Car Longer Life 2/6

10. Park in the shade

Of course, a garage is always the ideal place to park your car. But if one isn’t available, minimize interior damage from UV sunlight and heat by always trying to park your car in the shade. If no shade is available or if you find parking under a tree results in bird droppings, use a car shade to minimize the sun’s impact. As a bonus, you’ll have a cooler car to step into on hot sunny days. Car shades come in two basic types: those that you unfold and place on the front windshield and rear window, or pleated types that attach to the windshield posts (with adhesive), window frames (with Velcro), or the windows themselves (with suction cups).

Car Exterior: Tips To Keep Your Car Longer Life 3/6

21. Place a towel under baby seats

All manner of food bits and liquids can accumulate under a baby seat, where they can permanently stain the upholstery. Place a sheet of heavy plastic and an absorbent towel under the seat to prevent damage, and re-secure the seat according to the manufacturer’s directions.

22. Protect car paint from the sun

Paint does more than make your vehicle look great. It’s also the first line of defense against rusted body panels. Of course, the best way to protect the paint is to park the car in a garage. If that is not possible, park in the shade or purchase a car cover. The sun’s ultraviolet rays break down paint and cause it to fade. Some car covers protect your car from more than sun, moisture, bird droppings, and dust — they also have a thin layer of cushioning that will guard against light impact, such as from a tipped bicycle or small falling tree branch.

Tires, Wheels, and Brakes: Tips To Keep Your Car Longer Life 4/6

37. Keep the caps on

You step out into driveway ready to start your morning commute only to discover a flat tire. How in the heck did that happen overnight? If the tire valve is missing its cap, the culprit might be a leaky valve. Those little caps keep out dirt and moisture that can cause leaks, so be sure to keep caps on all your tire valves. Another tip: When you replace tires, remind the tire shop that you expect new valves with the tires.

38. Maintain proper inflation

Under-inflated tires are a tire salesman’s best friend. They create excessive heat and stress that can lead to tire failure. If you want to get every last mile out of your tires, get yourself a tire pressure gauge and use it at least once a month (more in hot weather) to keep your tires inflated to the recommendation in the vehicle’s owner’s manual. Check tires when they are cold (driven for less than one mile) for an accurate reading.
