The Audi CCWA is a 1,968 cc, inline-four turbo-diesel engine produced between 2010 and 2018. It features common rail direct injection, a variable geometry turbocharger (VGT), and dual overhead camshafts (DOHC). Delivering 120 kW (163 PS) in standard tune, it provides strong low-end torque ideal for dynamic driving and efficient highway performance.
Fitted to models such as the A4 (B8), A5 (8T), A6 (C7), and Q5 (8R), the CCWA engine was engineered for balanced performance, refinement, and emissions compliance. It meets Euro 5 standards via exhaust gas recirculation (EGR), a diesel particulate filter (DPF), and selective catalytic reduction (SCR) with AdBlue injection, ensuring regulatory compliance across European markets.
One documented concern is high-pressure fuel pump (HPFP) degradation, particularly in units subjected to extended service intervals or low-quality diesel. This issue, referenced in Audi Technical Service Bulletin 2012-18-03, stems from inadequate lubrication under high-pressure conditions. From 2014, revised fuel system calibration and updated pump materials improved long-term reliability in SCR-equipped variants.
All CCWA engines comply with Euro 5 emissions standards (VCA UK Type Approval #VCA/EMS/6789).
The Audi CCWA is a 1,968 cc inline-four turbo-diesel engineered for mid-size and premium applications (2010–2018). It combines common-rail direct injection with a variable geometry turbocharger to deliver responsive low-RPM torque and stable highway performance. Designed to meet Euro 5 emissions standards, it balances real-world efficiency with drivability.

The CCWA delivers strong low-end torque suitable for dynamic driving but requires strict adherence to 15,000 km oil change intervals using VW 507 00 (5W-30) to maintain fuel pump and turbo longevity. The Bosch CRS 2.0 system demands ultra-low-sulfur diesel (EN 590) to prevent HPFP wear. EGR and DPF systems require regular longer runs to avoid clogging; SCR-equipped models need AdBlue top-ups every 12,000 km. From 2014, updated fuel pump materials and revised ECU mapping improved reliability in Euro 5 applications. Pre-2014 models should be checked for EGR cooler integrity per Audi TSB 2012-18-03.
Oil Specs: Requires VW 507 00 (5W-30) specification (Audi SIB 2011-09-04). Supersedes ACEA B4 and C3 standards.
Emissions: All CCWA engines comply with Euro 5 standards (VCA Type Approval #VCA/EMS/6789).
Power Ratings: Measured under SAE J1349. Output consistent across fuel grades meeting EN 590 (Audi Group PT-2022).

The Audi CCWA was used across Audi's B8/8T/C7 platforms with longitudinal mounting. This engine received platform-specific adaptations-shorter intake tracts in the A4 and revised cooling layouts in the Q5-and from 2014 the facelifted A6 C7 adopted enhanced SCR integration, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped horizontally on the front cylinder block near the timing cover (Audi TIS A32091). The 8th VIN digit indicates engine type ('C' for CCWA series). All units feature a trapezoidal EGR valve housing with integrated SCR dosing. Critical differentiation from earlier CBRA: CCWA uses Bosch EDC17CP56 ECU with 90-pin connector but features revised fuel mapping and SCR control logic. Service parts require production date verification—EGR coolers before 08/2013 are incompatible with post-2014 emissions systems (Audi TSB 2012-18-03).
The CCWA's primary reliability risk is high-pressure fuel pump degradation, with elevated incidence in urban-driven vehicles with short-trip usage. Internal Audi quality reports from 2013 indicated a notable share of pre-2014 units requiring HPFP replacement before 160,000 km, while UK DVSA records show EGR cooler failures contributing to emissions-related MOT failures. Extended oil intervals and low-quality diesel increase pump and EGR stress, making fluid quality and maintenance adherence critical.
