The Audi CANB is a 1,798 cc, inline — four turbocharged petrol engine produced between 2012 and 2019. Part of the Volkswagen Group's EA888 Gen 3 engine family, it features direct fuel injection (FSI), variable valve timing (VVT), and a twin — scroll turbocharger. It delivers 132 kW (180 PS) in standard tune, with peak torque of 250 Nm available from 1,500 to 4,500 rpm, offering responsive performance across the rev range.
Fitted to models including the Audi A3 (8V), A4 (B8/B8.…
Production years 2012–2014 meet Euro 5 standards; 2015–2019 models comply with Euro 6b or 6c depending on market and emissions package .
The Audi CANB is a 1,798 cc inline-four turbocharged petrol engine designed for compact and mid-size applications (2012–2019). It combines direct injection with a twin-scroll turbocharger to deliver linear power delivery and strong mid-range torque. Engineered to meet Euro 5 and Euro 6 emissions standards, it balances performance with regulatory compliance and daily drivability.

The Audi CANB was used across Audi's 8V/8U platforms with transverse mounting and shared within the Volkswagen Group for longitudinal applications. This engine received platform-specific adaptations-shorter intake manifolds in the A3 and revised cooling routing in the Q3-and from 2015 the facelifted A4 B8.5 adopted revised emissions tuning, 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 CANB is generally robust when maintained properly, though pre-2016 models are prone to HPFP wear. Later revisions show improved fuel system durability. Regular oil changes with VW 502 00/505 00 oil, use of premium fuel, and periodic intake cleaning significantly enhance longevity beyond 200,000 km.
The most documented issues are HPFP wear, turbo wastegate sticking, intake valve carbon buildup, and oil leaks from degraded gaskets. These are covered in Audi service bulletins, particularly SIB 2014-10-05 for fuel system and SIB 2013-07-04 for timing system inspection.
The CANB engine was used in the Audi A3 (8V, 2013–2019), A4 (B8/B8.5, 2012–2015), and Q3 (8U, 2012–2018). It is part of the EA888 Gen 3 engine family shared across Volkswagen Group brands, including VW Golf 7 and SEAT Leon 1.8 TSI variants.
Aftermarket ECU tuning is common on the CANB 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 real-world conditions, the CANB achieves 6.5–7.8 L/100km (43–36 mpg UK) on mixed driving. Highway efficiency can reach 6.0 L/100km (47 mpg UK). Turbo efficiency and thermal management contribute to competitive consumption for its performance class.
No. The CANB uses a non-interference timing chain design. If the chain fails, valve-to-piston contact is unlikely, reducing the risk of catastrophic engine damage. However, chain replacement is still recommended at high mileage to prevent unexpected breakdowns.
Audi specifies VW 502 00 / 505 00 (SAE 5W-30) low-ASH synthetic oil. Change intervals are 15,000 km or 1 year. Using correct oil prevents turbo coking, injector fouling, and ensures proper chain lubrication.
