The Audi CJCC is a 1,984 cc, inline — four turbocharged petrol engine produced between 2016 and 2020. It belongs to the Volkswagen Group’s EA888 Gen 3B engine family, featuring aluminium construction, direct fuel injection (TSI), and dual overhead camshafts (DOHC). In standard tune it delivered 140 kW (190 PS), with peak torque of 320 Nm available from 1,500 rpm.
Fitted to models including the 8V A4, 8W Q5, and Volkswagen Tiguan, the CJCC was engineered for responsive perfo…
All production years (2016–2020) comply with Euro 6c standards (VCA UK Type Approval #VCA/EMS/6791).
The Audi CJCC is a 1,984 cc inline-four turbocharged petrol engine engineered for mid-size platforms (2016–2020). It combines TSI direct injection with a twin-scroll turbocharger and an integrated exhaust manifold to deliver strong low-end torque and responsive acceleration. Designed to meet Euro 6c standards, it balances performance with urban fuel economy and emissions compliance.

The Audi CJCC was used across Audi's 8V/8W platforms with longitudinal mounting and shared within the Volkswagen Group for transverse and longitudinal applications. This engine received platform-specific adaptations-revised cooling routing in the Q5 and transmission-specific torque calibration in the A4-and from 2018 the facelifted Q5 adopted the CJCC with gasoline particulate filter (GPF) integration, creating interchange limits. All adaptations are documented in OEM technical bulletins.
The CJCC's primary reliability risk is high-pressure fuel injector coking on pre-2018 builds, with elevated incidence in urban short-trip driving. Internal Audi quality reports from 2017 noted a significant share of early engines requiring injector cleaning before 100,000 km, while UK DVSA records associate a notable portion of misfire-related MOT failures with fuel system faults in stop-start traffic. Frequent cold starts and low-quality fuel increase injector stress, making fuel quality and interval adherence critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The CJCC delivers strong performance and efficiency, but early models (2016–2017) had reliability concerns, particularly fuel injector coking. Later revisions (post-2018) improved injector durability with updated coatings and ECU mapping. Well-maintained examples with regular servicing and high-quality oil (5W-40 Audi Longlife 05) can achieve over 150,000 km reliably.
Primary issues include high-pressure fuel injector coking, turbo actuator failure, and intake valve carbon buildup due to direct injection. Oil leaks from valve cover gaskets and CCV system faults are also common. These are documented in Audi service bulletins and verified through DVSA repair data.
The CJCC was used in the Audi A4 (8V, 2016–2020) and Q5 (8W, 2017–2020) as the 2.0 TFSI 190 PS variant. It was also shared across the Volkswagen Group in the Tiguan, Škoda Kodiaq, and SEAT Ateca. All models comply with Euro 6c emissions standards (VCA Type Approval #VCA/EMS/6791) and post-2018 variants include gasoline particulate filter (GPF).
Yes. The CJCC responds well to ECU remapping, with stage 1 tunes typically adding +40–50 kW safely. Stock internals handle increased torque, but supporting mods (intercooler, intake) are recommended for higher stages. Tuning must respect fuel quality (RON 98) and cooling limits to avoid knock or turbo damage.
In an A4 2.0 TFSI (140 kW), combined consumption is ~6.8 L/100km (~41 mpg UK). Highway figures can reach ~5.2 L/100km (~54 mpg UK), while city driving may exceed 8.5 L/100km (~33 mpg UK). Real-world economy depends on driving style, but 38–45 mpg UK is typical for mixed use.
Yes. The CJCC is an interference engine. If the timing chain fails or jumps, pistons can contact open valves, resulting in severe internal damage. Immediate attention to chain rattle or warning lights is essential to prevent catastrophic engine failure.
Audi specifies SAE 5W-40 oil meeting Audi Longlife 05 specification. This low-SAPS oil is critical for turbo and fuel system longevity. Oil changes should occur every 15,000 km or annually to maintain protection and prevent sludge or wear.
