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 .
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.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.

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.
Aftermarket ECU tuning is common on the PX platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
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.
