The Audi CSPB is a 1,798 cc, inline — four turbocharged petrol engine produced between 2012 and 2018. It forms part of the EA888 Gen 3 engine family, featuring direct fuel injection (FSI), variable valve timing (VVT), and a twin — scroll turbocharger. In standard tune, it delivers 125 kW (170 PS) and 250 Nm of torque, offering a balance of responsive performance and fuel efficiency for everyday driving.
Fitted to models such as the A3 (8V), A4 (B8), and Q3 (8U), the CSPB engine wa…
Production years 2012–2014 meet Euro 5 standards; 2015–2018 models comply with Euro 6 depending on market .
The Audi CSPB is a 1,798 cc inline-four turbocharged petrol engine engineered for compact and mid-size platforms (2012–2018). It combines fuel stratified injection (FSI) with a twin-scroll turbocharger to deliver responsive low-end torque and smooth power delivery. Designed to meet Euro 5 and later Euro 6 standards, it balances performance with regulated emissions compliance.

The Audi CSPB was used across Audi's MQB and MLB platforms with transverse or longitudinal mounting and shared with Volkswagen Group brands. This engine received platform-specific adaptations-integrated exhaust in the cylinder head and revised turbo routing in the A3-and from 2015 the updated EA888 Gen 3B variant introduced improved oil flow to the timing system, 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 CSPB offers strong performance and efficiency, but early models (2012–2014) had timing chain concerns. Later revisions (post-2015) improved oil flow and tensioner design, enhancing durability. Regular maintenance using VW 502 00 oil and 15,000 km service intervals greatly improves long-term reliability.
Key issues include timing chain wear (especially pre-2015), intake valve coking due to direct injection, turbo actuator failures, and PCV-related oil consumption. These are documented in Audi service bulletins and field reports, with timing chain being the most critical if maintenance is deferred.
The CSPB engine was used in the Audi A3 (8V), A4 (B8), and Q3 (8U) from 2012 to 2018. It was also shared across Volkswagen Group models including the Volkswagen Golf 7 (1.8 TSI). All variants produce 170 PS and meet Euro 5 or Euro 6 emissions depending on model year.
Aftermarket ECU tuning is common on the CSPB 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 CSPB achieves ~6.5 L/100km (43 mpg UK). Highway efficiency improves to ~5.8 L/100km (49 mpg UK), while city driving may reach 8.0 L/100km (35 mpg UK). Real-world consumption depends on driving style, but 38–45 mpg UK is typical for mixed use.
Yes. The CSPB is an interference engine. If the timing chain fails, pistons can collide with open valves, causing catastrophic internal damage. Immediate attention to chain rattle or oil pressure warnings is essential to prevent engine destruction.
Audi specifies SAE 5W-30 oil meeting VW 502 00 (petrol) or 505 00 (multi) standards. Use of correct oil is critical for timing chain lubrication. Change intervals should not exceed 15,000 km or one year to maintain engine longevity and prevent premature wear.
