The Audi PX is a 1,984 cc, inline — four petrol engine produced between 2012 and 2020. It forms part of the Volkswagen Group’s EA888 engine family, featuring turbocharging, direct fuel injection (TSI), and variable valve timing on both intake and exhaust camshafts (AVS). In standard tune, it produces 169 kW (230 PS) and 350 Nm of torque, delivering strong mid — range performance suitable for sport — oriented applications.
Fitted to models such as the Audi A4 (B8), A5 (8T), and…
Production years 2012–2014 meet Euro 5 standards; 2015–2020 models comply with Euro 6 (VCA UK Type Approval #VCA/EMS/6789).
The Audi PX is a 1,984 cc inline-four turbocharged petrol engine from the EA888 series (2012–2020). It combines direct fuel injection with dual variable valve timing to deliver responsive performance and improved fuel efficiency. Designed to meet Euro 5 and Euro 6 standards, it powers mid-to-high-end Audi models with a focus on driving dynamics and refinement.

The Audi PX was used across Audi's B8/8V platforms with transverse mounting and shared within the Volkswagen Group. This engine received platform-specific adaptations-reinforced mounts in the S3 and revised ECU tuning in the A5-and from 2016 the facelifted A4 B8.5 adopted the PX evolution with updated fuel pump and GPF, creating interchange limits. All adaptations are documented in OEM technical bulletins.
The PX's primary reliability risk is high-pressure fuel pump degradation on early builds, with elevated incidence in aggressive or track use. Internal Audi quality reports from 2015 indicated a notable share of pre-2016 engines requiring HPFP replacement before 100,000 km, while UK DVSA records link a significant portion of misfire-related MOT failures to fuel trim faults in high-mileage examples. Extended idling and poor-quality fuel increase pump stress, making oil quality and fuel additive use critical.
Analysis derived from Audi technical bulletins (2012–2020) and UK DVSA failure statistics (2015–2023). Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The PX engine offers strong performance and refinement, but early models (2012–2015) had reliability concerns, particularly high-pressure fuel pump failures. Later revisions (post-2016) improved pump durability, so well-maintained examples can be robust. Regular servicing and using correct oil (5W-40 VW 502 00) significantly enhance longevity.
The primary issues are high-pressure fuel pump wear, ignition coil failures, and intake carbon buildup. Oil leaks from the valve cover gasket are also common on high-mileage units. These concerns are documented in Audi technical bulletins and supported by DVSA failure data. Preventative maintenance is key to long-term reliability.
The 2.0L PX petrol engine was used in the Audi A4 (B8/B8.5, 2012–2016), A5 (8T, 2012–2016), and S3 (8V, 2013–2020) as the 2.0 TFSI (230 PS) variant. It was also shared with the Volkswagen Golf R (7.5). All models meet Euro 5 or Euro 6 emissions standards.
Yes. ECU remaps can yield +30–50 kW on stage 1 due to conservative factory tuning. The EA888 block and internals are robust, supporting forced induction upgrades. However, ensure HPFP and cooling upgrades accompany higher power levels to maintain reliability.
In combined driving, the PX achieves approximately 7.8 L/100km (36.2 mpg UK) in the A4 and 8.2 L/100km (34.4 mpg UK) in the S3. Real-world consumption typically ranges between 30–38 mpg UK depending on driving style and conditions.
Yes. The PX is an interference engine. If the timing chain fails or jumps, pistons may contact open valves, causing severe internal damage. Immediate attention to any timing rattle or DTCs is essential to prevent costly repairs.
Audi specifies 5W-40 oil meeting VW 502 00 (petrol) or 505 00 (multi-vehicle) standards. Use only high-quality synthetic oil and adhere to 15,000 km or annual service intervals to ensure proper turbo and chain lubrication and engine longevity.
