Audi 2.0 TDI CGL Engine

The Audi 2.0 TDI CGL (specifically the CGLA/CGLB/CGLC series) is a highly refined 2.0-liter, four-cylinder common-rail diesel engine. Part of the EA189 family, the “CGL” generation represents a major leap forward from older pump-duse (PD) engines, offering a much smoother, quieter, and more efficient driving experience. Key Specifications & Features Type: 2.0L Inline 4-Cylinder, 16-Valve Diesel Valvetrain: Double Overhead Cam (DOHC) Induction: Variable Geometry Turbocharger (VGT) with Intercooler Fuel System: Bosch Common Rail Direct Injection (1800 bar) Power Output: Typically 120 kW to 130 kW (163–177 hp) at 4,200 rpm. Torque: A stout 380 Nm available from 1,750 to 2,500 rpm. Emission Standard: Euro 5 compliant. Performance Highlights Refinement: Unlike older diesel engines, the CGL series uses piezo injectors and a common-rail system, which virtually eliminates the harsh “clatter” at idle and during acceleration. Fuel Efficiency: Known for exceptional long-distance economy, often achieving under 5.0L/100km on open highway runs in sedan bodies. Dynamic Torque: The Variable Geometry Turbo (VGT) provides a very linear power delivery, making the car feel responsive even in higher gears at highway speeds. Build Quality: Features a cast iron block for longevity and an aluminum alloy head to reduce weight over the front axle. Common Applications The CGL engine is the primary powerplant for several premium Audi models: Audi A4 (B8) (2.0 TDI models, 2011–2015). Audi A5 (Coupe and Sportback variants). Audi Q5 (2.0 TDI Quattro models). Audi A6 (C7) (Early 2.0 TDI models).
