Chain cam is used in the 1.8 and 2.0 gasoline engines. The 1.4 was initially a chain, however in 2014 the switch to a belt was made due to the chains’ poor performance. All four-cylinder diesel engines need belts.

When should an Audi Q3’s timing belt be replaced?
Although they can last up to 100,000 miles, it’s always a good idea to change them before that. The valves, pistons, and other internal engine components can sustain significant damage in the event of a belt failure.
Is there a timing belt or chain 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 belt or chain on a 2015 Audi Q3?
The Q3 offered a variety of engine options with varied horsepower ratings, front-wheel drive, all-wheel drive, gasoline engines, turbo-diesel engines, different engine sizes, and manual or automatic transmission.
The 103kW turbo-diesel engine that powered the Series 1 vehicles (sold from 2012 to 2015) had a starting output of 103kW and 320Nm of torque.
The same engine was also available in a 130kW/380Nm tune for an additional cost, and it was well-liked when turbo-diesel was fashionable.
A 125 TFSI with 125 kW and 280 Nm was the base petrol engine; the same engine was also available with a 155 kW/300 Nm tune.
It had a 1.4-liter turbo-petrol engine with a 110kW/250Nm output known as the 110 TFSI.
The more potent petrols and diesels could be obtained with all-wheel drive, which was Audi’s more straightforward form of “Quattro” and let the car act as a front-wheel drive until wheel slip was detected. The 110 TFSI and 103 TDi were only offered with front-wheel drive.
There were two different gearbox options: a six-speed manual or a six- or seven-speed dual-clutch transmission from Audi.
The mechanical line-up was slightly simplified as a result of the Series II upgrade for 2015, with the 110 TFSI joining the 110kW turbo-diesel, 135kW turbo-diesel, and 132kW turbo-petrol.
Except for the 110TFSI base model, all Q3s lost the manual transmission and switched to all-wheel drive.
Timing chains rather than timing belts were used in petrol engine Q3s, which should have meant less maintenance but sometimes didn’t (see Any Issues).
The turbo-diesel all-wheel drive variants of the Q3 could tip the scales at closer to 1600kg, while the lighter versions were quite trim with a kerb weight of less than 1500kg.
Is used Q3 trustworthy?
In July 2017, a recall was issued because the parking brake may cause brake light failure. It affects Q3s created between February 10, 2014, and January 10, 2016. If you have any questions, check with your neighborhood Audi dealer or visit the DVSA website, which includes a list of the impacted vehicle identifying numbers (VINs).
Is a used Audi Q3 estate reliable?
In our previous reliability assessments, this particular Audi Q3 always placed in the middle to upper-middle of the table. In the most recent one, this generation placed close to the top in the category for family SUVs when it was powered by gasoline, but close to the bottom when powered by diesel.
Audi Q3: Is it a Quattro?
On slick conditions, Audi’s quattro all-wheel drive system will improve your traction. It’s important to think about whether you live somewhere that has significant cold spells or in a rural area where mud is frequently spread on the road by agricultural equipment. Quattro will improve your Audi’s handling, even on slick surfaces.
Additionally, Audi adds quattro to its performance models, such as the RS3 and RS4, which struggle to transmit their power to the road if they were only equipped with two wheels.
Offroad is where it makes the most sense because the extra traction it provides is so valuable. Only the top-tier versions of the Q3 feature quattro, unlike the majority of Audi’s SUVs, such as the Q5, Q7, and Q8, which all come standard with it.
Which beautifully takes us to towing. A worthwhile option is quattro if you frequently hitch a caravan. When a Q3 35 TDI is equipped with quattro four-wheel drive, the towing capacity rises to 2200kg from the 2000kg that a 35 TDI with front-wheel drive can support.
More importantly, it will lessen the drama associated with towing. When you take off, you’ll feel the quattro digging into the pavement, which should increase the stability of the vehicle at higher speeds. Then, following an overnight downpour, your quattro-equipped Audi will make quick work of pulling your caravan out of a muddy campsite when your vacation is done and you’re on your way home.
After five years, should I update the timing belt?
When to change your cam belt is not a fixed rule. Your car’s make, model, and how frequently you drive it are all factors. Over the course of a vehicle’s lifetime, it will typically need to be replaced more than once.
Timing belt replacement is typically advised by manufacturers after a certain number of years or miles. This might take between 40,000 and 100,000 kilometers or more than four years.
When is My Audi Due for Service?
There are usually two options depending on the service regime you choose. Regardless of the Audi service plan you select, your Multi-Media Interface and myAudi account will notify you when it’s due for a service.
Flexible Audi Service Regime
- Based on oil degradation, oil service. Maximum of two years or 18,600 miles, whichever comes first.
- Every 18,600 miles or two years, whichever comes first, requires an inspection service.
Fixed Audi Service Regime
- 9300 miles or one year, whichever comes first, for oil changes.
- Every 18,600 miles or two years, whichever comes first, an inspection is required.
There is no mileage cap on the fixed-inpsection service that some electric Audi vehicles receive every two years.
Which Audi models come with timing chains?
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.
Timing 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.
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.
