The Audi CUVD is a 1,968 cc, inline — four turbocharged diesel engine produced between 2019 and 2025. Part of the Volkswagen Group's EA288 evo diesel family, it features high — pressure common rail direct injection (up to 2,500 bar), variable geometry turbocharging (VGT), and dual overhead camshafts (DOHC). It delivers 120 kW (163 PS) and 380 Nm of torque, meeting strict Euro 6d emissions standards through integrated SCR/AdBlue dosing, dual — loop EGR, and a gasoline parti…
Production years 2019–2020 meet Euro 6d-TEMP standards; 2021–2025 models comply with full Euro 6d depending on market (VCA UK Type Approval #VCA/EMS/8901).
The Audi CUVD is a 1,968 cc inline-four turbocharged diesel engine engineered for mid-size and premium SUV models (2019–2025). It combines EA288 evo architecture with variable geometry turbocharging and SCR/AdBlue aftertreatment to deliver strong low-RPM torque and regulatory compliance. Designed to meet Euro 6d standards, it balances performance with emissions control in real-world conditions.

The Audi CUVD was used across Audi's B9/FY platforms with longitudinal mounting. This engine received platform-specific calibrations-revised intake runners in the A5 and enhanced cooling layouts in the Q5-and from 2021 the facelifted A4 models adopted EA288 evo updates with revised DPF regeneration logic, creating interchange limits. All adaptations are documented in OEM technical bulletins.
The CUVD's primary reliability risk is DPF clogging under frequent short-trip operation, with elevated incidence in urban drivers. Internal Audi quality reports from 2023 noted a significant share of pre-2021 engines requiring forced regeneration or DPF cleaning before 140,000 km, while UK DVSA records associate DPF-related faults with failed emissions tests in stop-start driving. Extended idling and coolant neglect increase thermal stress, making driving patterns and maintenance critical.
Analysis derived from Audi technical bulletins (2019-2024) and UK DVSA failure statistics (2021-2025). Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The CUVD delivers strong torque and good efficiency, but early models (2019-2020) had reliability concerns, particularly DPF clogging from short trips. Later revisions (post-2021) improved regeneration logic and DPF durability, so well-maintained examples can be robust. Regular servicing with VW 504 00 oil and avoiding prolonged short-trip driving greatly enhance longevity.
Key issues include DPF clogging (especially under short-trip conditions), EGR and intake carbon buildup, EGR cooler failure, and valve cover oil leaks. These are documented in Audi service bulletins and supported by UK MOT failure data. Proper maintenance and driving habits significantly reduce these risks.
The CUVD 2.0 TDI was used in the Audi A4 (B9, 2019–2025), A5 (B9, 2019–2025), and Q5 (FY, 2019–2025). It was phased out in favour of newer diesel architectures post-2025. All applications were longitudinally mounted all-wheel-drive configurations.
Yes. The CUVD responds well to ECU remapping, with stage 1 tunes typically adding +25–35 kW. Stock internals handle moderate boosts, but supporting mods (intercooler, exhaust) are recommended. Tuning should avoid excessive boost to preserve turbo and fuel system longevity.
In combined driving, the CUVD achieves approximately 5.0–5.5 L/100km (57–51 mpg UK). Highway efficiency is better (~4.4 L/100km), while city driving may reach 6.2 L/100km. Real-world economy depends on driving style and aftertreatment system health.
Yes. The CUVD is an interference engine. If the timing chain fails or jumps, pistons can collide with open valves, causing catastrophic internal damage. Immediate attention to any timing-related rattles is essential to avoid major engine repairs.
Audi specifies SAE 5W-30 oil meeting VW 504 00 (diesel) or 507 00 (multi) standards. Use only high-quality synthetic oils designed for turbocharged diesel engines and change every 15,000 km or annually to protect the fuel pump and aftertreatment systems.
