The Audi CZVA is a 1,968 cc, inline — four turbo — diesel engine produced between 2015 and 2021. It belongs to the Volkswagen Group’s EA288 engine family, featuring common rail direct injection, a variable geometry turbocharger (VGT), and a cast — iron block with an aluminium head. In standard tune, it delivers 110 kW (150 PS) with peak torque of 340 Nm available from 1,750 rpm, providing strong low — end pull ideal for daily driving and towing.
Fitted to models including the Aud…
All CZVA models comply with Euro 6b (2015–2018) and Euro 6d-TEMP (2019–2021) depending on market .
The Audi CZVA is a 1,968 cc inline-four turbo-diesel engine engineered for transverse applications (2015–2021). It combines common rail injection with a variable geometry turbocharger to deliver responsive low-end torque and highway efficiency. Designed to meet Euro 6 standards, it balances performance with emissions compliance in front-wheel-drive platforms.

The Audi CZVA was used across Audi's 8V/B9 platforms with transverse mounting and shared within the Volkswagen Group for compact and mid-size applications. This engine received platform-specific adaptations-shorter exhaust manifolds in the A3 and revised cooling circuits in the Q3-and from 2019 the Euro 6d-TEMP revision introduced updated SCR calibration and ECU software, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.

The most common questions about engine codes, what they mean, how to find them and how this database works
The CZVA is generally reliable when maintained properly, but DPF clogging is common in city-driven vehicles. Later models (post-2018) benefit from revised fuel pump calibration and improved regeneration logic. Regular oil changes using Audi Longlife Diesel VW 507.00 (0W-30) and periodic highway driving are essential for long-term reliability.
Key issues include DPF clogging, high-pressure fuel pump wear, EGR system fouling, and AdBlue dosing faults. These are documented in Audi technical bulletins and field reports, with preventative maintenance being critical. Urban driving exacerbates DPF and EGR issues, while poor fuel quality accelerates pump wear.
The CZVA engine was used in the Audi A3 (8V, 2015–2020), A4 (B9, 2016–2021), and Q3 (8U, 2015–2018), all in 2.0 TDI configuration. It was also shared across Volkswagen Group brands including the Golf Mk7. Applications vary by emissions standard and model year.
Aftermarket ECU tuning is common on the CZVA platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
In combined driving, the CZVA achieves approximately 4.2–4.8 L/100 km (67–59 mpg UK). Real-world consumption varies by model and driving style, with A3 and A4 sedans typically returning 55–60 mpg UK on mixed routes. Highway efficiency is strong due to tall gearing and efficient combustion.
Yes. The CZVA is an interference engine, meaning piston-to-valve contact will occur if the timing chain fails or jumps. This can result in severe internal damage. Maintaining the engine per Audi specifications, including oil changes and regeneration cycles, is critical to avoid costly repairs.
Audi specifies SAE 0W-30 oil meeting Longlife Diesel VW 507.00 specification. This low-SAPS oil is formulated to protect turbo bearings, prevent DPF ash accumulation, and support SCR system longevity. Oil changes should be performed every 15,000 km or annually, whichever comes first.
