The Audi CABB is a 1,798 cc, inline — four turbocharged petrol engine produced between 2012 and 2018. It features TFSI (Turbo Fuel Stratified Injection), DOHC valvetrain, and variable valve timing on both intake and exhaust camshafts. In standard tune, it delivers 132 kW (180 PS) and 250 Nm of torque, offering improved responsiveness over earlier EA888 Gen 2 units.
Fitted to models such as the 8V A3, 8S S3, and B8.5 A4, the CABB engine was engineered for sportier performance a…
Production years 2012–2014 meet Euro 5 standards; 2015–2018 models comply with Euro 6b depending on market .
The Audi CABB is a 1,798 cc inline-four turbocharged petrol engine developed for compact and mid-size Audi applications (2012–2018). It builds on the EA888 Gen 3 architecture with dual injection (direct + port), improved thermal management, and enhanced turbo response. Designed to meet Euro 5 and Euro 6b standards, it delivers strong mid-range performance with better fuel efficiency than its predecessors.

The Audi CABB was used across Audi's 8V/8S/B8.5 platforms with transverse mounting and shared with Seat and Skoda under VW Group modular strategy. This engine received platform-specific adaptations-tighter intake tuning in the S3 and revised cooling in the A4-and from 2015 the facelifted A3 Sportback adopted updated fuel pump cooling, 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 CABB offers strong performance and improved efficiency over earlier EA888 units, but early models (2012–2014) had reliability concerns, particularly HPFP failures. Later revisions (post-2015) improved pump cooling and durability, so well-maintained examples can be quite robust. Regular servicing and using high-quality fuel (RON 98) greatly aid longevity.
The biggest issues are high-pressure fuel pump degradation, turbo wastegate actuator sticking, and intake swirl flap failure. Other complaints include oil leaks from gaskets and occasional PCV or EGR faults. These are well-documented in Audi service bulletins and technical reports.
This 1.8L turbo petrol was used widely across Audi's compact and mid-size lineup (Euro 5/6b era models). It appeared in the A3 (8V), S3 (8S), and A4 (B8.5), primarily as the 1.8 TFSI. It was also used in Seat Leon and Skoda Octavia under VW Group sharing. In all cases, it was phased out by 2018 in favour of newer EA888 Gen 3 variants.
Aftermarket ECU tuning is common on the CABB 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.
Moderate. In an A3 1.8 TFSI (132 kW) from around 2014, typical consumption is ~8.8 L/100km (city) and ~5.9 L/100km (highway), or about 39 mpg UK combined. Real-world figures depend on driving style, but expect 35–44 mpg (UK) on mixed roads for a healthy CABB engine.
Yes. The EA888 series (like most modern Audis) is an interference engine. This means if the timing chain jumps or breaks, pistons can hit open valves, causing serious engine damage. That's why chain maintenance is critical - any warning rattles should be addressed immediately.
Audi specifies a 5W-40 synthetic oil meeting Audi Longlife-04 spec. Always use a quality oil designed for turbo petrol engines and change it at regular intervals (around 15,000 km or as Audi recommends) to ensure proper turbo and chain lubrication.
