Audi Fuel Pump

How A Clogged Fuel Pump Affects Your Audi’s Mileage

Posted on May 23, 2022 by smikyautomowp

European automotive companies are known across the world for producing high-quality, dependable, and efficient automobiles that last a lifetime. Audi is one of the most successful car manufacturers, exhibiting some of the most innovative designs and technologically advanced technical elements.

Audi creates each vehicle to give an unrivaled driving experience underpinned by durability, high performance, efficiency, and elegance. Audi cars can last up to a mileage of over 190,000 miles, but they can begin to deteriorate much sooner if your Audi starts having issues with its fuel pump. To ensure that your Audi continues to perform optimally, you are required to maintain a routine maintenance schedule with a certified automotive expert.

The Gas Mileage of your Audi

The Audi A4 outperforms most entry-level luxury vehicles, offering excellent value for money. Gas mileage is excellent on the Audi A4 with a highway rating of 34 mpg and a city rating of 26 mpg. Not bad for a car that has great acceleration and pep on the highway.

The Audi A3 Sedan 2022 model can attain up to 38 mpg on the highway, 29 mpg in the city, and 32 mpg combined, this makes it the gasoline-powered Audi car with the highest fuel efficiency. However, there are different factors that can cause a deterioration in your Audi’s gas mileage, all of which can be traced down to poor maintenance. One of these factors is a clogged fuel pump, which can be very detrimental to the overall performance of your car.

Your Audi’s fuel pump transfers gas from the gas tank to the engine, allowing it to function smoothly. If the pump becomes clogged, damaged, or malfunctions as a result of overheating, the engine will not receive enough gasoline to operate optimally.

Consider a defective or malfunctioning relief valve in the fuel pump if you find yourself refilling your gas tank more than normal. If the valve is faulty, it will not open as needed, thereby causing surplus gasoline to enter the engine system. Unfortunately, the surplus gasoline cannot be utilized or stored within the engine, so it burns up and causes problems, one of them being reducing gas mileage.

In order to avoid the occurrence of such, it is important to understand the problem as well as the possible causes of its impending failure.

Possible Causes of A Clogged or Faulty Fuel Pump

As earlier stated the fuel pump is in charge of transferring gasoline from the fuel tank to the engine. An apparently straightforward process that can easily be jeopardized when external factors impact the pump’s functioning. The following are some of the most typical reasons for fuel pump failure:

  • A Clogged Filter: When the fuel filter in the fuel pump becomes clogged, it restricts the flow of gasoline, resulting in many symptoms, such as hesitation, stalling, and backfiring of the car’s engine. More crucially, it has the potential to lead to the destruction of the fuel pump. Most modern cars do not have separate changeable fuel filters. Instead, the fuel filter is integrated into the fuel pump and is not accessible separately. This is bad since gasoline quality is a serious issue, and a blocked filter may need the installation of a new fuel pump. Buying only high-quality fuel is more vital than ever.
  • Fuel Contamination: Moisture, dirt, and corrosion can all introduce visible impurities into the tank, putting the fuel at high risk. The tank might become rusted and deposit rust particles into the fuel. Contaminants in the gasoline tank are pulled through the fuel pump, regardless. The pump’s strainer can only remove particles of sizes larger than 70 microns. (There are 25,400 microns in an inch.) Regrettably, many smaller particles of sizes within the range of 30-40 microns slip straight through and do the majority of the harm to the engine. The contaminants that enter the pump damage the commutator and motor brushes.
