The FSI engine is propelled by a timing belt system that synchronizes the rotation of the crankshaft, camshafts, and cylinder head. This Audi A4’s timing belt system uses a corded/molded rubber timing belt that is wear-resistant and highly durable (a.k.a. Audi A4 toothed belt).

Is there a timing belt or chain on the Audi A4?
The Audi A4 features a variety of engines with either a timing belt or a timing chain from the model years 1996 to 2021. 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 can I tell whether my Audi uses a timing chain or belt?
The first step is to examine your engine to determine whether your car has a timing belt or a timing chain. If you see a tinplate or plastic cover on the side of your engine, you have a timing belt. Your engine has a timing chain if it lacks one of those.
There are a few instances where this rule isn’t true, but thankfully they are uncommon. For instance, a dry belt is concealed under the engine of the Peugeot Pure Tech. Consult your car’s owner’s manual or the manufacturer’s website if you have questions about your vehicle that you can’t figure out by looking at the engine. Alternately, schedule a visit with WhoCanFixMyCar at your neighborhood mechanic.
Is there a timing belt or chain on the Audi 2.0 T?
Time for another 2.0L TSI Audi engine tip! Owners of 2008 or newer Audi and VW vehicles are well acquainted with the 2.0L Turbo Straight Injection (TSI) 4-cylinder engine. These engines were created to have the least amount of displacement while still producing a large amount of power.
For the most part, the 2.0L TSI is a well-built engine. With far higher fuel efficiency, it can produce 200 horsepower and the feel of a 6-cylinder engine. Yet there is one significant impediment. The timing chain in these engines has the potential to be extremely problematic.
Numerous customers have visited German Auto Center for complete engine rebuilds after the timing chain tensioner failed. When the timing chain becomes faulty, this “stretched (by as much as 2 inches), which results in the chain jumping and all the valves bending. The engine is essentially wrecked after this occurs.
What then triggers this timing chain stretching that destroys engines? soiled oil Many motorists are unaware that worn-out oil that isn’t lubricating the timing chain rollers might accelerate their deterioration. Timing chain rollers deteriorate with use, and this is when the “Stretching takes place.
We are starting to encounter 1-2 Audis each week that need extensive engine repairs because the issue is so widespread. It’s a problem that often surfaces shortly after the warranty expires, around the 60,000-mile mark.
Fortunately, the solution is relatively simple. Change the oil much more frequently than the 20,000-mile interval Audi advises (after the first five). Our technicians now advise that you replace your oil every 5,000 miles because they have dealt with timing chain problems repeatedly. Additionally, a substance like complete Mobile 1 synthetic oil is recommended.
This frequency will keep your oil clean so that problems with your timing chain and tensioner are avoided, combined with high-quality oil and filters. This type of maintenance is worthwhile because dirty oil also contributes to a ton of other engine issues.
More frequent oil changes cost a bit more, but you’ll save thousands by preventing an engine disaster that renders your car inoperable.
Has a 2008 Audi A4 has a timing chain or belt?
Every Audi A4 produced between 2010 and 2021 has an interference engine with a timing chain. All 4 cylinder A4s use timing belts from 2007 to 2008, whereas V6s have chains.
In 2008, the sedans have a timing chain while the cabriolets (convertibles) have a timing belt.
For instance, whereas the 2009 Audi A4 2.0L 4 Cyl. Turbo 200 horsepower (FSI), Cabriolet option has a timing belt, the 2021 Audi A4 2.0L 4 Cyl. Turbo 201 hp (40) option has a timing chain.
Audi started using timing chains when?
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.
It’s vital to keep in mind that modern German performance cars, whether you drive a Porsche, Mercedes Benz, BMW, Volkswagen, or Audi, will last you for many miles and years if you maintain them properly.

When should the timing belt of an Audi A4 be changed?
Err on the side of caution and replace your Audi A4’s timing belt every 90,000 miles when performing important timing belt maintenance. Our advice is to thoroughly check all timing belt parts before the suggested interval.
Timing chains: how long do they last?
When should a timing chain be changed? Unless there is a specific issue, the timing chain typically needs to be replaced between 80,000 and 120,000 miles. In automobiles with higher mileage, chain problems are frequent.
Timing belts or chains: which is superior?
Timing belts typically last less time than timing chains. Timing belts are made of rubber, which isn’t as strong as metal, but chains are made of metal, and this is the simple explanation for why this is the case. Timing belts are not weak, but they will probably need to be replaced at some point, whereas a chain can last the lifetime of the car.
Timing belts typically need to be replaced in the mileage range of 55,000 miles (about 90,000 km) and 90,000 miles (roughly 150,000 km). Therefore, a timing belt is still a very reliable and significant component of your car.
Whether your car has a timing chain or belt, it’s critical that you watch for any symptoms of wear and strain and take appropriate action. Depending on the sort of engine you have, a broken timing belt can have disastrous results. You could be better off searching to get a new vehicle if the repairs are too expensive to be practical.
