The Audi CGLD is a 1,984 cc, inline — four turbocharged petrol engine produced between 2013 and 2020. It features direct fuel injection (TSI), turbocharging, and dual overhead camshafts (DOHC) with variable valve timing on both intake and exhaust. In standard output form, it delivers 140 kW (190 PS), with torque peaking at 320 Nm between 1,500 and 4,500 rpm, providing strong mid — range responsiveness and smooth power delivery.
Fitted to models such as the 8V A3, 8W A4, B9 A5,…
All production years (2013–2020) comply with Euro 6 emissions standards depending on market .
The Audi CGLD is a 1,984 cc inline-four turbocharged petrol engine designed for compact and mid-size models (2013–2020). It combines TSI direct injection with a single-scroll turbocharger to deliver responsive mid-range torque and efficient fuel consumption. Engineered to meet Euro 6 emissions standards, it balances drivability with regulatory compliance across European markets.

The Audi CGLD was used across Audi's 8V/8W/3G platforms with transverse mounting and integrated start-stop functionality. This engine received platform-specific adaptations—reinforced engine mounts in the A6 and revised intake manifolds in the A3—and from 2018 the facelifted A4 B9.5 adopted revised EGR routing, 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 CGLD delivers strong performance and good efficiency, but early models (2013–2016) had reliability concerns, particularly timing chain tensioner wear. Later revisions (post-2017) improved durability, so well-maintained examples can be quite robust. Regular servicing and using high-quality oil (5W-40 Audi Longlife-01) greatly aid longevity.
The biggest issues are timing chain tensioner wear (leading to rattling or failure), intake valve carbon buildup, and turbo wastegate actuator sticking. Other complaints include oil leaks from the valve cover gasket and occasional EGR faults. These are well-documented in Audi service bulletins.
This 2.0L turbo petrol was used widely across Audi's lineup (Euro6 era models). It appeared in the A3 (8V), A4 (8W), A5 (8T), and A6 (3G), with variants including 2.0 TFSI 190 PS. It was phased out by 2020 in favor of EA888 evo4 units with improved efficiency and reduced emissions.
Aftermarket ECU tuning is common on the CGLD 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.
Good for a turbo petrol engine. In an A4 2.0 TFSI (2015), typical consumption is ~9.2 L/100km (city) and ~6.1 L/100km (highway), or about 38 mpg UK combined. Smaller models (A3) with the same engine often achieve slightly better economy. Real-world figures depend on driving style, but expect 36–42 mpg (UK) on mixed roads for a healthy CGLD engine.
Yes. The CGLD series (like most modern Audis) is an interference engine. This means if the timing chain fails or jumps, pistons can collide with open valves, causing severe internal damage. That's why tensioner and chain maintenance is critical—any cold-start rattles should be investigated immediately.
Audi specifies a 5W-40 synthetic oil meeting Audi Longlife-01 (or newer) spec. Always use a high-quality oil designed for turbocharged direct-injection engines and change it every 15,000 km or as Audi recommends to ensure proper chain lubrication and minimize carbon buildup.
