The Audi A5 has been a popular compact coupe since 2007. Most motoring journalists favorably view it. However, fuel system problems sullied the model's reputation. Most, but not all, of these snags are traced to a defectively-designed fuel pump.
The fuel system must deliver a proper mixture of air and fuel to the engine for efficient combustion. The job of the fuel induction system is to provide the engine with a correct air-fuel mixture in all driving ranges from idle to wide-open throttle.
An electric fuel pump delivers gasoline into the combustion chamber of your Audi. It's engineered to be long-lasting, but like any part, it can fail. That's when replacement becomes necessary.
Here are the indicators of a bad fuel pump in your Audi:
- Engine "chokes" or struggles to maintain speed
- Noises, backfires, and a sputtering engine
- Hesitation when starting or accelerating
- Any of the above issues, along with a "Check Engine" light
