probably a bad spark, itll cause your engine to misfire flooding petrol in without igniting it, when it sparks afterwards it ignites causing a bang and backfire.
What is a car misfire?
A misfire is when one of the cylinders is accelerating without actually doing anything, it's just a dead-cylinder. In order to fix this you need to tighten the cylinder or adjust the engine connector.

Differece between backfire misfire?
"Backfire" and "misfire" are two distinct engine-related issues that can occur in internal combustion engines. Let's understand the difference between the two: Backfire: Backfire is a situation where the combustion process in the engine's cylinders occurs at an unexpected time or place. Instead of the normal progression of combustion from the intake stroke to the power stroke, unburnt fuel or exhaust gases ignite in the intake manifold or the exhaust system. This results in a sudden and loud popping or banging noise. Causes of Backfire: Timing issues: Incorrect ignition timing can lead to fuel igniting at the wrong time. Fuel-air mixture: A too-rich or too-lean fuel-air mixture can cause backfires. Faulty exhaust system: A damaged or leaking exhaust system may allow exhaust gases to ignite inappropriately. Backfires can be harmful to the engine and should be addressed promptly to prevent damage. Misfire: Misfire occurs when one or more cylinders in the engine fail to ignite the air-fuel mixture during the combustion process. As a result, the engine skips the power stroke in those cylinders, leading to a loss of power, rough idling, and potentially increased exhaust emissions. Causes of Misfire: Ignition problems: Faulty spark plugs, ignition coils, or ignition leads can prevent proper ignition. Fuel delivery issues: Problems with fuel injectors or fuel pressure can lead to inadequate fuel supply. Compression problems: Issues with cylinder compression, such as worn piston rings or valves, can cause misfires. Misfires can be intermittent or persistent, and diagnosing the underlying cause is essential to prevent further engine damage and restore normal engine operation.
Will a bad timing chain make the engine backfire?
Incorrect Timing Can Cause Backfire.
Audi a4 2.6 backfires when accelerate?
Have the OBDII ran, take it to a advanced auto parts to see if there is a code you may be running rich, or a number of other problems my Audi had a minor misfire which didn't flag the check engine light but caused an occasional backfire because the fuel was being exhausted. If the engine shudders it could be a misfire. Or its possible that your intake filter is clogged.

How the car react when a Cylinder does not work?
The LS is prone to coil failure which leads to a misfire in the affected cylinder. A misfire due to a failing coil usually happens when the engine is warm and under load (low RPMs, accelerating or going uphill). The misfire may feel like a transmission problem because it causes the car to buck and stutter as though the gears were skipping or getting stuck briefly. The worse the misfire gets, the harder it will be to accellerate. Sometimes the misfire condition can be overcome by applying more RPMs or reducing the load on the engine. See my post about the valve cover leaking issues contributing to this issue.
