The Audi CGKA is a 1,395 cc, inline — four turbocharged petrol engine produced between 2010 and 2016. Part of the Volkswagen Group's EA211 engine family, it features a transverse mounting configuration, aluminium construction, and direct fuel injection (TSI). With a rated output of 81 kW (110 PS) and 200 Nm of torque, it delivers responsive urban performance with compact packaging for front — wheel — drive applications.
Fitted to models including the Audi A1 (8X), A3 (8V),…
Production years 2010–2013 meet Euro 5 standards; 2014–2016 models comply with Euro 6 (VCA UK Type Approval #VCA/EMS/6789).
The Audi CGKA is a 1,395 cc inline-four turbocharged petrol engine designed for compact front-wheel-drive platforms (2010–2016). It combines TSI direct injection with a compact turbocharger and integrated exhaust manifold to deliver strong low-end torque. Engineered to meet Euro 5 and Euro 6 standards, it prioritises weight savings and thermal efficiency for urban-focused applications.

The Audi CGKA was used across Audi's 8X/8V platforms with transverse mounting and shared within the Volkswagen Group for compact applications. This engine received platform-specific calibrations-shorter intake runners in the A1 and revised cooling routing in the A3-and from 2014 updated tensioner materials improved timing belt longevity, creating interchange limits. All adaptations are documented in OEM technical bulletins.
The CGKA's primary reliability risk is timing belt wear in high-temperature environments, with elevated incidence in vehicles used for short-trip driving. Internal Audi quality reports from 2015 noted increased tensioner failures in pre-2014 units before 120,000 km, while UK DVSA MOT data shows catalytic converter degradation as a leading cause of emissions failures. Urban operation and poor fuel quality amplify system stress, making oil and fuel specification adherence critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The CGKA offers good fuel economy and adequate performance for city use, but pre-2014 models have documented timing belt tensioner reliability issues. Post-2014 revisions with improved tensioner materials enhance durability. Strict maintenance, use of premium petrol (RON 95+), and adherence to oil and timing belt intervals are essential for long-term reliability.
Key issues include timing belt tensioner wear, intake valve carbon buildup, turbo boost leaks, and oil leaks from the valve cover gasket. These are documented in Audi service bulletins, particularly SIB 2013-08 for timing system improvements. Urban driving and low-quality fuel exacerbate carbon and emissions system issues.
The CGKA engine was used in the Audi A1 (8X, 2010–2015) and A3 (8V, 2013–2016). It was also shared across Volkswagen Group models including the SEAT Ibiza Mk5 and Škoda Fabia III. It was phased out in favour of updated EA211 evo variants with improved efficiency and emissions post-2016.
Yes, the CGKA responds well to ECU remapping. Stage 1 tunes typically achieve 140–150 PS safely. However, increased boost and fuel pressure stress the turbo and injectors, so supporting modifications and high-quality maintenance are strongly advised to maintain reliability.
In mixed driving, the CGKA achieves approximately 5.8–6.2 L/100km (46–48 mpg UK). Highway efficiency is around 5.0 L/100km (56 mpg UK), while city driving may reach 7.0 L/100km (40 mpg UK). Real-world figures depend on driving style, fuel quality, and vehicle condition.
Yes, the CGKA is an interference engine. If the timing belt fails, pistons will contact open valves, resulting in severe internal damage. Adhering to the 150,000 km or 6-year replacement interval is critical to avoid costly repairs.
Audi specifies VW 502 00 / 505 00 (SAE 5W-30) synthetic oil. This formulation is essential for turbocharger and timing system longevity. Oil changes should be performed every 15,000 km or annually to maintain engine health and prevent sludge buildup.
