Durable CDAA CDAB Engine for Volkswagen Audi

Gen 2 EA888 1.8T CDAA/CDAB Engine – High-Performance Bare Engine for Volkswagen Group Vehicles

The Gen 2 EA888 1.8T CDAA and CDAB engine is a precision-engineered power unit developed by the Volkswagen Group, designed to deliver exceptional performance, fuel efficiency, and reliability across a wide range of premium compact and mid-size vehicles. This bare engine assembly represents a significant evolution in turbocharged inline-four technology, offering enhanced torque delivery at low RPMs while maintaining high output under load—making it ideal for drivers who demand both responsiveness and economy.

Key features include direct injection (FSI), twin-scroll turbocharging, variable valve timing (VVT), and variable valve lift systems—all integrated into a robust long-block design that ensures durability and ease of installation. These innovations not only improve combustion efficiency but also reduce emissions, aligning with modern environmental standards without compromising driving dynamics.

Engine specifications include:

• Direct Injection Fuel System – Ensures precise fuel metering and optimal air-fuel mixture for improved thermal efficiency and reduced carbon deposits.
• Twin-Turbocharging Technology – Utilizes exhaust gas energy to boost intake pressure, resulting in stronger acceleration and better throttle response.
• Advanced Variable Valve Timing – Dynamically adjusts camshaft timing for intake and exhaust valves to optimize airflow and maximize power across all engine speeds.
• Variable Valve Lift Mechanism – Adapts valve lift based on engine load and speed, improving volumetric efficiency and reducing pumping losses during partial load conditions.

This engine is specifically engineered for use in various models from Audi, Skoda, Seat, and Volkswagen, including the Audi A3, A4, A5, TT; Skoda Superb, Yeti, Octavia; Seat Leon, Toledo, Altea XL; and VW Passat, Golf, CC, and others. Whether you're replacing a failed unit or building a performance-oriented engine build, this CDAA/CDAB long block provides an excellent foundation for upgrades or restorations. It comes as a complete engine assembly ready for installation after proper remapping and tuning, ensuring compatibility with OEM control modules and emission systems.

Common applications span European-market vehicles such as the VW Passat B7/B8, Skoda Superb Mk2, Audi A4 B8, and Seat Leon Mk2, where its balanced power curve and smooth operation have earned praise among enthusiasts and mechanics alike. The engine’s modular design supports easy integration with existing drivetrain components, minimizing downtime during repairs or swaps.

Users frequently highlight its consistent performance in real-world conditions—especially in urban environments where low-end torque makes city driving effortless—and its ability to maintain peak output over extended periods without overheating or mechanical degradation. Many owners report smoother idle behavior and quieter operation compared to earlier generations, thanks to refined internal components and updated harmonic balancing.

Frequently asked questions often revolve around compatibility, remapping requirements, and expected lifespan. While the engine can be installed directly into compatible platforms, professional tuning is recommended to ensure optimal calibration of the ECU, especially when integrating with aftermarket parts like high-flow injectors or upgraded intercoolers. With regular maintenance—including oil changes, spark plug replacements, and coolant system checks—the EA888 Gen 2 engine typically lasts well beyond 200,000 kilometers, demonstrating its engineering excellence and long-term value.
