The Volkswagen CXGA is a 1,984 cc, inline‑four turbocharged petrol engine produced between 2016 and 2023. It features direct fuel injection (TSI), dual overhead camshafts (DOHC), and variable valve timing, delivering 162 kW (220 PS) and 350 Nm of torque. Its turbocharged direct injection system enables strong low‑end response with improved fuel economy compared to naturally aspirated alternatives.
Fitted to performance variants such as the Golf Mk7.5 GTI, Golf R, an…
Production years 2016–2018 meet Euro 6b standards; 2019–2023 models comply with Euro 6d-TEMP .
The Volkswagen CXGA is a 1,984 cc inline‑four turbocharged petrol engine engineered for hot hatches and compact performance sedans (2016–2023). It combines gasoline direct injection with a single turbocharger and a gasoline particulate filter to deliver responsive power and strong low‑rpm torque. Designed to meet Euro 6b and Euro 6d-TEMP emissions standards, it balances sporty performance with regulatory compliance.

The Volkswagen CXGA was used across Volkswagen's Mk7.5 platform with transverse mounting and shared with Audi for longitudinal applications. This engine received platform-specific adaptations—reinforced engine mounts in the Golf R and revised cooling in the Golf GTI Performance—and from 2020 the Audi S3 facelift adopted the DNUE variant with GPF and updated ECU maps, 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.
Analysis derived from manufacturer technical service bulletins and industry workshop records. Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The CXGA offers strong performance and refined operation, but early units (2016–2018) are prone to intake carbon buildup and GPF clogging in urban use. Later revisions (post-2019) improved PCV and regeneration strategies. With strict adherence to oil changes (using VW 504/507 oil) and regular highway driving, well-maintained examples can exceed 200,000 km reliably.
Top issues include intake valve carbon buildup, GPF clogging, turbo wastegate rattle, and timing chain tensioner wear. These are documented in Volkswagen service bulletins like SIB 2017‑12 and SIB 2016‑09, especially affecting pre-2019 builds.
The CXGA powered the Golf Mk7.5 GTI Performance (2017–2020), Golf R (2017–2020), and Audi S3 (8V facelift, 2016–2019). All are Euro 6b/Euro 6d-TEMP–compliant performance variants sharing the 220 PS 2.0 TSI platform.
Aftermarket ECU tuning is common on the CXGA 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.
Real-world consumption is ~9.8 L/100km (city) and ~6.5 L/100km (highway), or ~29 mpg UK combined. Expect 27–32 mpg (UK) on mixed roads. Economy suffers with aggressive driving, short trips, or if carbon buildup restricts airflow.
Yes. The CXGA is an interference engine. Timing chain failure or jump can cause piston-to-valve contact, resulting in catastrophic damage. Immediate attention to chain rattle or timing faults is essential.
Volkswagen specifies 5W‑30 synthetic oil meeting VW 504 00 or 507 00 standards. Always use manufacturer-approved oil and change every 10,000–15,000 km to protect the HPFP, turbo, GPF, and timing system.
