The Audi A3 features a variety of engines with either a timing belt or a timing chain from the model years 2006 to 2020. All of its engines, though, are disruptive.
In a combustion engine, the timing belt (or chain) maintains the correct synchronization between the various engine parts.
Serious engine damage may result if the belt or chain strains or breaks.
Timing chains are typically rated for the lifespan of the engine, while timing belts have a suggested replacement interval, however they do need to be inspected on occasion.
Understanding the timing system in your car or a potential purchase might help you save future costs and hassles.

How long does an Audi A3 timing chain last?
According to the maintenance plans for an Audi, the timing chain can easily last 120,000 miles without experiencing any issues. Service professionals, however, are observing Audi timing chains failing significantly more quickly. An internal combustion engine needs precise, mechanical engine timing in order to function effectively. More specifically, the camshafts and crankshafts need to operate in unison. The crucial connection between the crankshaft and camshaft is provided by timing chains.
The chain is twisted securely around the pulleys and gears thanks to tensioners. The timing of the engine is thrown off if the tensioner malfunctions and the chain becomes slack. Additionally, if the timing chain breaks free, you should brace yourself for major and expensive issues. The pistons will sustain damage by coming into touch with the valves, the valves will bend, and the engine might potentially be destroyed if the timing chain snaps or jumps while you are driving.
Is there a timing chain or belt on my Audi?
So what distinguishes a timing chain from a timing belt? Both a timing chain and belt perform the same basic function. These mechanisms are created to maintain the relative position of the valves opening and closing to the position of the piston as the engine is running, regardless of whether you drive a Porsche, Mercedes Benz, or BMW with an internal timing chain, or an Audi or Volkswagen with an external timing belt. When a valve is opened at the incorrect time, it may come into contact with the piston and cause a catastrophic engine failure.
The piston will raise (building compression) and the valves will open precisely, allowing air and fuel to enter the combustion chamber and exhaust to depart in less than one thousandth of a second in an engine with perfectly timed ignition. When valves open or close prematurely or lately due to a timing issue, the piston will be driven into the valve, most frequently bending the valve and possibly punching a hole in the piston crown, rendering the engine worthless. These fixes could cost as little as $4,000 to $5,000 or, depending on the engine, much more.
An internal timing chain is used by brands including Porsche, BMW, and Mercedes-Benz. These chains are stronger and less prone to break on their own. The same outcome is more frequently experienced when other chain-holding components, including chain tensioners and chain guides, fail. Check engine lights and a rattling sound, which is typically heard while starting an engine, are early warning indicators of a breakdown.
Initially using timing chains, Audi and Volkswagen switched to an external timing belt in the 1980s, 1990s, and the majority of the 2000s (now returning to chain drive systems). The timing belt is simpler to inspect and replace than the timing chain. On most models, replacing a timing belt with all associated parts (including a water pump on most models) costs between $700 and $900, which is significantly less than doing the same for a timing chain. The external timing belt’s drawback is that, like all belts, it eventually wears out and needs to be replaced. Timing belts should typically be changed every 80,000 miles, or every five years. Each time they are serviced or at least once a year, these should be visually inspected.

Is there a timing chain or belt on an Audi S3?
The Audi S3 features a variety of engines with either a timing belt or a timing chain from the model year 2000 to 2020. All of its engines, though, are disruptive.
Do I have a timing chain or belt?
Take a brief glance at the engine to see whether it uses a chain or a belt system. It runs a timing belt if the front has plastic coverings since the timing belt is dry and does not require further protection.
What is an interference engine from Audi?
You may find out if your car’s engine is an interference engine or a non-interference engine by looking at the list below. If the cam stops turning owing to a damaged timing belt, an interference engine is one that has insufficient clearance between the valves and pistons. Usually, this leads to catastrophic engine failure. A non-interference engine doesn’t work like that. Knowledge is power.
