The Audi CCWB is a 1,968 cc, inline-four turbo-diesel engine produced between 2010 and 2018. It belongs to the Volkswagen Group's EA189 engine family, engineered for optimal fuel efficiency and responsive low-end torque. Equipped with common rail direct injection (CRDI), a variable geometry turbocharger (VGT), and double overhead camshafts (DOHC), it delivers 105 kW (143 PS) and 320 Nm of torque, supporting strong urban drivability and efficient highway cruising.
Fitted to models such as the A3 (8V), A4 (B8/B9), and Q3 (8U), the CCWB was designed for balanced performance and real-world economy in compact and mid-size applications. Emissions compliance is achieved via exhaust gas recirculation (EGR), a diesel particulate filter (DPF), and selective catalytic reduction (SCR) in certain markets, enabling Euro 5 and later Euro 6 compliance depending on model year and region.
One documented reliability concern is premature high-pressure fuel pump (HPFP) wear, noted in Audi Technical Service Bulletin 2012-04-02. This issue affects early production units and is linked to fuel contamination or suboptimal filtration. From 2013, revised pump internals and updated fuel filter specifications were introduced to improve durability and reduce field failures.
Production years 2010–2014 meet Euro 5 standards; 2015–2018 models comply with Euro 6 depending on market (VCA UK Type Approval #VCA/EMS/6789).
The Audi CCWB is a 1,968 cc inline-four turbo-diesel engineered for compact and mid-size models (2010–2018). It combines common-rail direct injection with a single variable-geometry turbocharger to deliver responsive low-RPM performance. Designed to meet Euro 5 and Euro 6 emissions standards, it balances real-world economy with drivability.

The VGT turbo provides strong low-end torque ideal for city driving but demands strict maintenance to prevent EGR/DPF clogging and turbo actuator binding. VW 504 00/507 00 (5W-30) oil is essential due to its low-ash formulation protecting the DPF. Extended oil intervals increase soot loading and can trigger limp mode. The Bosch HPFP is sensitive to fuel quality; ultra-low-sulfur diesel (EN 590) is mandatory to prevent premature wear. EGR cooler inspections are recommended every 60,000 km to prevent carbon-induced flow restrictions. Post-2013 units benefit from revised HPFP internals and updated EGR valve calibration per Audi SIB 20 06 08.
Oil Specs: Requires VW 504 00 / 507 00 specification (Audi SIB 20 06 08). Replaces ACEA B4/C3 standards for DPF-equipped diesels.
Emissions: Euro 5 applies to 2010–2014 models only (VCA Type Approval #VCA/EMS/6789). Euro 6 compliance from 2015 varies by market and SCR fitment.
Power Ratings: Measured under SAE J1349 standards. Output remains consistent across markets with EU3+ diesel (Audi TIS Doc. A34810).

The Audi CCWB was used across Audi's 8V/B8/B9 platforms with longitudinal mounting and shared within the Volkswagen Group for transverse applications. This engine received platform-specific adaptations-shorter intake manifolds in the A3 and revised EGR routing in the Q3-and from 2015 the facelifted A4 B9 adopted updated ECU calibration and SCR integration in select markets, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped horizontally on the front face of the cylinder block, near the timing cover (Audi TIS A34130). The 7th VIN digit indicates engine family ('C' for EA189 series). Pre-2013 models have silver valve covers with black plastic cam covers; post-2013 units use all-black covers. Critical differentiation from EA288: CCWB uses Bosch CRS 2-20 injection with round ECU connector, while EA288 uses CRS 3-20 with rectangular connector. Service parts require production date verification - HPFP and EGR valves for pre-2013 models are not interchangeable with later units (Audi SIB 20 06 08).
The CCWB's primary reliability risk is high-pressure fuel pump (HPFP) wear, with elevated incidence in urban driving with frequent short trips. Internal Audi quality reports from 2013 noted a significant share of pre-2013 units requiring HPFP replacement before 100,000 km, while UK DVSA records show EGR-related faults contributing to emissions test failures. Extended oil intervals and low-quality diesel exacerbate fuel system and DPF stress, making adherence to VW 504 00 oil and EN 590 fuel standards critical.
