The fuel cap in your Audi may experience some type of failure over the duration that you own the car. The fuel cap is a small, yet extremely important part of your vehicle’s emission system. Below we will discuss a few things to look out for that may lead you to suspect your fuel cap needs to be replaced.

Your Audi’s Fuel Cap

A gas cap, also known as a fuel filter cap, is possibly one of the most important, smaller parts of your Audi. The fuel cap maintains the fuel system vacuum pressure seal allowing the combustion system to perform as it should.

To access the fuel filter cap, you will need to open the fuel bay door of your vehicle. The cap is key in sealing off your fuel tank from dust, dirt, debris, and moisture. Any of these things getting into your fuel tank may result in some hefty repairs.

Warning Signs

As we discussed above, the fuel cap is one of the most important parts of your Audi. A loose or broken fuel cap may not leave you stranded on the side of the road, but it is not something to ignore. In order to know if your cap becomes loose or goes bad, let’s dig a little deeper into some signs to look for and what to do should you find yourself with a faulty fuel filter cap:

• You may smell gas within the passenger compartment of your vehicle.
• You may notice an illuminated check engine light.
• When you close the fuel cap you do not hear the “click”.
• After tightening the cap, it pops back out.

An improperly sealed and tightened fuel filter cap may cause an evaporation system leak, which is why you may notice the check engine light illuminated. This is often one of the most common causes for this light to appear.

Damaged Fuel Cap Seal

Your fuel filter cap may become loose or damaged for several reasons, including normal wear and tear. The more times you loosen and tighten your fuel cap to put gas into your vehicle, you are potentially causing damage to the seal.

It is important to have your vehicle inspected by a trained professional if you begin to notice the smell of gasoline within the passenger compartment as this is extremely flammable. If left untreated, you run the risk of your Audi catching fire while you are driving.

To determine the cause of your illuminated check engine light, a professional will need to run diagnostic testing with an engine code reader. You also may need to have an evaporation system check done to ensure no further damage was caused by the loose fuel filter cap.
