The Audi CAGC is a 1,395 cc, inline-four turbocharged petrol engine produced between 2012 and 2016. It features direct fuel injection (TSI), dual overhead camshafts (DOHC), and variable valve timing on both intake and exhaust camshafts. In standard tune, it delivers 81 kW (110 PS) and 200 Nm of torque, offering responsive low-end performance ideal for urban driving and efficient highway cruising.
Fitted to models including the A1 (8X), A3 (8V), and SEAT Ibiza Mk5, the CAGC engine was engineered for compact vehicle applications where space and fuel efficiency are prioritized. Emissions compliance was achieved through a three-way catalytic converter and lambda control, meeting Euro 5 standards for all production years. The engine's modular design allows integration with start-stop systems and brake energy recuperation.
One documented concern is premature timing chain wear, particularly in early production units. This issue, referenced in Audi Service Information Bulletin 2013-08-05, is linked to inadequate lubrication at the chain tensioner during cold starts. From mid-2013 onward, revised tensioner design and updated oil pump calibration were implemented to improve durability.
All production years (2012–2016) meet Euro 5 emissions standards (VCA UK Type Approval #VCA/EMS/6789).
The Audi CAGC is a 1,395 cc inline-four turbocharged petrol engine designed for compact applications (2012–2016). It combines direct fuel injection with a single-scroll turbocharger to deliver strong low-RPM response and balanced fuel economy. Engineered to meet Euro 5 standards, it supports start-stop functionality and integrates with 7-speed S tronic transmissions.

The CAGC's turbocharging provides strong low-RPM pull ideal for city driving but requires adherence to 15,000 km oil change intervals using Audi Longlife-01 (5W-30) to maintain timing chain and turbo longevity. Extended idling and short-trip driving increase carbon buildup on intake valves due to port omission in direct injection. Regular highway runs help maintain throttle body and turbo efficiency. Post-2013 models benefit from updated chain tensioner design; pre-2013 units should have the revised kit installed per Audi SIB 2013-08-05. Start-stop system integration demands healthy battery and alternator condition.
Oil Specs: Requires Audi Longlife-01 (5W-30) specification (Audi SIB 2013-08-05). Supersedes ACEA A1/B1 standards.
Emissions: All CAGC variants comply with Euro 5 standards (VCA Type Approval #VCA/EMS/6789).
Power Ratings: Measured under SAE J1349. Output consistent across EU markets with 95 RON fuel (Audi TIS Doc. A33011).

The Audi CAGC was used across Audi's 8X/8V platforms with transverse mounting and shared with SEAT under VW Group modular strategy. This engine received platform-specific tuning—higher idle stability in the A1 and revised torque delivery in the A3 Sportback—and from 2013 the 8V A3 facelift adopted updated timing components, creating partial interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped vertically on the left-side cylinder block near the exhaust manifold (Audi TIS A32801). The 8th VIN digit indicates engine type ('D' for CAGC series). Pre-2013 models have a silver valve cover with black plastic timing cover; post-2013 units use an all-black cover. Critical differentiation from EA211: CAGC has a rear-mounted timing chain with Bosch HDEV5 injectors, while EA211 uses front chain and different ECU placement. Service parts require production date verification—timing kits for engines before 07/2013 are incompatible with later tensioner revisions (Audi SIB 2013-08-05).
The CAGC's primary reliability risk is timing chain wear on early builds, with elevated incidence in vehicles used for frequent short trips. Internal Audi quality reports from 2014 indicated a significant share of pre-2013 units required chain replacement before 120,000 km, while UK DVSA MOT data links intake carbon buildup to frequent urban driving. Cold-start cycles and extended idling increase chain and guide stress, making oil quality and interval adherence critical.
