The Audi CCZA is a 1,968 cc, inline — four turbo — diesel engine produced between 2012 and 2018. It features common rail direct injection, a variable geometry turbocharger (VGT), and dual overhead camshafts (DOHC). In standard tune, it delivers 85 kW (116 PS) and 250 Nm of torque, designed for efficient urban and regional driving in Audi's compact and mid — size models.
Fitted to models such as the A1 (8X), A3 (8V), and Q3 (8U), the CCZA engine was engineered for cost — effective o…
Production years 2012–2015 meet Euro 5 standards; 2015–2018 models comply with Euro 6b depending on market .
The Audi CCZA is a 1,968 cc inline-four turbo-diesel engineered for compact and mid-size models (2012–2018). It combines common-rail direct injection with a variable geometry turbocharger to deliver responsive low-end torque and efficient city driving. Designed to meet Euro 5 and Euro 6b standards, it balances economy with regulatory compliance.

The Audi CCZA was used across Audi's 8X/8V/8U platforms with transverse mounting in front-wheel-drive models. This engine received platform-specific adaptations—reinforced engine mounts in the Q3 (8U) and revised intake manifolds in the A1 (8X)—and from 2015 the Euro 6 update introduced SCR and AdBlue injection, 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 CCZA is generally robust when maintained properly, but models with extended oil intervals or poor fuel quality are prone to HPFP and EGR issues. Post-2015 Euro 6 variants include SCR and improved diagnostics, enhancing longevity. Regular 15,000 km services with Audi Longlife-05 oil and use of high-quality diesel significantly improve reliability.
The most common issues are high-pressure fuel pump wear, EGR/DPF clogging, turbo actuator sticking, and timing chain tensioner rattle. These are documented in Audi service bulletins and are often linked to service neglect or short-trip driving. Using proper oil and fuel and allowing regular regeneration cycles mitigates most risks.
The CCZA engine was used in the A1 (8X, 2012–2018), A3 (8V, 2013–2018), and Q3 (8U, 2012–2018). It was phased out in favor of EA288 Evo engines post-2018. All variants produce 85 kW (116 PS) and 250 Nm, with Euro 5 and Euro 6b emissions compliance depending on model year.
Aftermarket ECU tuning is common on the CCZA 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 CCZA achieves approximately 4.2–5.0 L/100 km (56–67 mpg UK). Highway consumption can be as low as 3.8 L/100 km (74 mpg UK), while city driving may reach 5.8 L/100 km (49 mpg UK). Real-world economy depends on driving style, vehicle weight, and DPF regeneration frequency.
Yes. The CCZA is an interference engine, meaning that if the timing chain fails or jumps, pistons can collide with open valves, causing catastrophic internal damage. Proper maintenance of the chain tensioner and adherence to oil service intervals are essential to prevent such failures.
Audi specifies SAE 5W-30 oil meeting Longlife-05 specification. This low-ash formulation is critical for protecting the turbocharger, EGR system, and DPF. Oil changes should be performed every 15,000 km or annually to ensure optimal engine longevity and emissions system function.
