Audi is a German automotive brand headquartered in Ingolstadt, Germany. They produce some of the most luxurious automobiles worldwide. While Audi is known for its high performance and exceptional comforts and amenities, there are factors that can cause an engine misfire in your Audi.
An engine misfire occurs when the cylinders fail to produce enough power, resulting in incomplete combustion inside at least one cylinder head. As a driver, if your vehicle experiences engine misfire you may notice:
- vehicle hesitation
- vehicle shaking
- illuminated check engine light
What causes an engine misfire?
There are several factors associated with engine misfire in Audis from failing spark plugs to faulty sensors. Below are the most commonly reported causes of engine misfire among Audi drivers and experts.
Ignition system problems
The Audis ignition system is responsible for the actual combustion process that ignites a spark resulting in the engine starting. Ignition system failure is a gradual problem that occurs over time rather than producing immediate symptoms.
The main sources of engine misfire caused by an ignition system problem are:
- ignition coil failure
- one or more failed spark plug
- ignition cable failure
- a faulty distributor cap
Improper air/fuel mixture
Many parts work together to produce the perfect air/fuel ratio within the combustion chamber of your Audi. A proper air/fuel mixture is ignited by the spark plugs allowing the engine to start. Several things can throw off the air/fuel mixture resulting in engine misfire including:
- fuel pump failure
- a clogged or dirty fuel filter
- damage to the oxygen sensor
Transmission issues
Problems within the transmission system are the cause of several issues within Audis including engine misfire. If you experience engine misfire in addition to trouble shifting gears, this is an obvious sign that the transmission system is associated with the misfire. It is important to have your vehicle inspected thoroughly as soon as possible to avoid costly damage to both the transmission and engine.
Engine control module problems
Modern vehicles are equipped with smart features including an onboard computer designed to communicate with the various control modules throughout your Audi to ensure all parts are working as designed. The Engine Control Module (ECM) is the main control module designed to control the function of the engine itself.
With the modern technology in Audis, technical issues may arise. These issues may include a miscommunication among the control modules, specifically the ECM, resulting in an engine misfire. Experts recommend having your vehicle brought to an Audi expert for a diagnostic inspection to prevent total engine failure.
Engine Misfire Symptoms
There are several tell-tale signs of engine misfire including:
- a loss of engine power
- trouble starting the engine
- an increase in fuel consumption
- odd noises, such as popping sounds from the engine
- exhaust backfires
- engine jerking, vibrations, or stalling
- an increase in emissions
