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 (VCA UK Type Approval #VCA/EMS/7890).
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.
The CGLD's primary reliability risk is timing chain tensioner wear on early builds, with elevated incidence in urban driving with frequent cold starts. Internal Audi quality reports from 2017 noted a significant share of pre-2017 engines requiring tensioner replacement before 130,000 km, while UK DVSA records link a notable portion of emissions-related MOT failures to EGR clogging in stop-start traffic. Short-trip cycles and extended oil intervals increase chain and guide stress, making oil quality and interval adherence critical.

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.
Yes. The CGLD is quite tunable. ECU remaps routinely gain +40–60 kW safely on stage 1, as the stock internals handle increased torque well. Aftermarket upgrades (intercooler, exhaust, intake) can further boost power. Enthusiasts frequently remap 2.0 TFSI models for sharper throttle response. Any tuning should include supporting modifications to avoid overstressing the engine.
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.
