The Audi RS3 has developed somewhat of a cult following in performance car circles. With its superior handling, comfortable interior, and compact size, it delivers an exceptionally smooth drive.
But it’s the powerful engine that really turns heads. Under the hood, the Audi RS3 features a 2.5 TFSI engine. A five-cyclinder turbo-charged unit, it delivers exceptional power that has to be seen to be believed.
One of the most sought-after models is the Audi RS3 DAZA engine. Installed in the RS3 hatchback between 2017 and 2018, the DAZA engine is regarded as one of Audi’s best motors.
And with good reason. Let’s take a look at what makes this engine so admired.
Key features of the Audi RS3 DAZA engine
The Audi RS3 DAZA engine is in demand not just for its amazing features, but for its short-lived reign.
The engine code, DAZA, is only found on those Audi RS3s produced between 2017 and 2018. It was discontinued in 2018, the last of its line before the RS3 began being fitted with a particulate filter in the exhaust.
This was noticed by RS3 fans. Some say the filter works to reduce the classic RS3 sound, muffling the personality it’s known for. It also serves to reduce the power that can be achieved from an RS3 ECU tune.
To its fans, the Audi RS3 DAZA engine is the pure essence of the RS3. And there’s a reason it’s developed such a following.
Pure power
The RS3 DAZA motor features a turbocharged 2480cc five-cylinder, dual-injection engine. It’s capable of delivering impressive amounts of power, with the ability to go from 0-100km/h in just four seconds flat.
The classic DAZA configuration is also known for its unique sound, delivering a gruff, throaty rumble that sends a chill down the spine. It’s an auditory demonstration of its satisfying power.
Highly tuneable
Build for performance, the DAZA engine is prized among collectors for the added power it can achieve with a successful RS3 ECU tune.
A stock DAZA engine is already capable of putting out an incredible 400 horsepower. An RS3 Stage 1 tune can add an extra 70+ horsepower. An RS3 Stage 2 tune can go upwards of an extra 100 horsepower—hitting over 500 horsepower, vastly increasing its power delivery.
For the DAZA engine, a high-quality RS3 ECU tune pushes the engine’s output to impressive levels while maintaining its signature drivability and reliability. It enables sharper, more immediate throttle input, enhancing the driving experience and making the motor feel more alive.
An RS3 ECU tune can also remove the speed limiter, allowing the car to be tuned for even faster launches off the starting block. While not useful for daily driving, it can significantly enhance the thrill when taking it out on the track.
Safe on the road
The RS3 features the Audi quattro all-wheel-drive system, which is a hallmark of the brand’s engineering. The system combines the practicality of AWD with dynamic handling, the ideal mix for such a powerful vehicle.
The RS3’s quattro AWD system provides superior stability in low traction environments. It modulates power delivery to ensure safe handling, improving response times and boosting safety on the road.
Inside, the DAZA engine’s ECU is equipped with sophisticated software that monitors and adjusts engine parameters in real-time. This allows it to maintain optimal performance and prevent any internal damage. The turbocharger is equipped with safeguards to manage boost pressure and prevent overboost situations that could harm the engine.
A look at RS3 DAZA motor reliability
The Audi RS3 DAZA engine is famed as a workhorse, delivering an exceptional drive both on and off the track.
As well as the impressive performance delivered by this remarkable engine, it’s also become known for signature DAZA motor reliability.

Known issues with the Audi RS3 DAZA engine

It’s known for receiving carbon build-up on the cast aluminium silicon alloy cylinder heads. However, this is an issue that’s easily resolved with a trip to your trusted specialty European car mechanic.
It’s also known to have fuel pump issues, where the the system stops providing fuel to the engine. This puts increased stress on the cam shaft, and can cause the car to lose power while driving.
