The Audi CJEE is a 1,968 cc, inline-four turbo-diesel engine produced between 2015 and 2020. It features common rail direct injection, a variable geometry turbocharger (VGT), and dual overhead camshafts (DOHC) with dual-mass flywheel integration. In standard output form, it delivers 110 kW (150 PS), with higher outputs reaching 140 kW (190 PS) and torque between 340–400 Nm, providing strong low-end responsiveness for daily driving.
Fitted to models such as the 8V A3, 8W A4, B9 A5, and 3G A6, the CJEE engine was engineered for balanced performance, fuel economy, and emissions compliance in compact and mid-size platforms. It meets Euro 6 emissions standards through exhaust gas recirculation (EGR), diesel particulate filter (DPF), and selective catalytic reduction (SCR) with AdBlue injection, ensuring regulatory compliance across European markets.
One documented reliability concern is premature wear of the high-pressure fuel pump, particularly in vehicles subjected to extended service intervals and non-compliant diesel fuel. This issue, referenced in Audi Service Bulletin 2016-17-05, is linked to inadequate lubrication and contamination in the common rail system. From 2017 onward, Audi introduced revised fuel filtration and updated service protocols to mitigate the risk.

All production years (2015–2020) comply with Euro 6 emissions standards depending on market (VCA UK Type Approval #VCA/EMS/9012).
The Audi CJEE is a 1,968 cc inline-four turbo-diesel engine designed for compact and mid-size models (2015–2020). It combines Bosch CRS 3-20 common-rail injection with a single variable-geometry turbocharger to deliver responsive low-RPM torque and efficient highway cruising. Engineered to meet Euro 6 emissions standards, it balances drivability with regulatory compliance across European markets.

The single VGT turbo provides strong low-RPM torque ideal for urban driving but requires adherence to 15,000 km oil change intervals using Audi Longlife-04 (5W-30) to prevent high-pressure fuel pump wear. Cold-start idling should be minimized to ensure rapid oil pressure buildup and reduce guide stress. The Bosch CP4 fuel pump demands ultra-low-sulfur diesel (ULSD) meeting EN 590 standards to prevent internal damage. Post-2017 models feature enhanced fuel filtration; pre-2017 units should be inspected per Audi SB 2016-17-05. EGR/DPF/SCR systems require regular highway runs to maintain regeneration cycles and prevent limp-mode events.
Oil Specs: Requires Audi Longlife-04 (5W-30) specification (Audi SB 2016-17-05). Supersedes ACEA C3 requirements.
Emissions: All production years (2015–2020) meet Euro 6 standards depending on market (VCA Type Approval #VCA/EMS/9012).
Power Ratings: Measured under SAE J1349 standards. 140 kW output requires EU3+ fuel quality (Audi TIS Doc. A36600).

The Audi CJEE was used across Audi's 8V/8W/3G platforms with longitudinal mounting and integrated AdBlue dosing. This engine received platform-specific adaptations—reinforced mounts in the A6 and revised intake manifolds in the A3—and from 2018 the facelifted A4 B9.5 adopted updated SCR calibration, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped horizontally on the left-side engine block near the exhaust manifold (Audi TIS A36050). The 7th VIN digit indicates engine family ('C' for CJEE series). Pre-2017 models have silver valve covers with black plastic timing covers; post-2017 units use black valve covers. Critical differentiation from EA288: CJEE uses Bosch EDC17CP74 ECU with trapezoidal diagnostic port, while EA288 uses EDC17CP56 with round port. Service parts require production date verification—fuel pumps for engines before 08/2016 are incompatible with later units due to internal revisions (Audi SB 2016-17-05).
The CJEE's primary reliability risk is high-pressure fuel pump wear on early builds, with elevated incidence in urban driving with frequent short trips. Internal Audi quality reports from 2017 noted a significant share of pre-2017 engines requiring pump replacement before 120,000 km, while UK DVSA records link a notable portion of emissions-related MOT failures to EGR clogging in stop-start traffic. Cold-start cycles and extended oil intervals increase pump and guide stress, making oil quality and interval adherence critical.
