The Volkswagen CYZA is a 1,395 cc, inline‑four turbocharged petrol engine produced between 2012 and 2020. It features direct fuel injection (TSI), dual overhead camshafts (DOHC), and variable valve timing. In standard form it delivers 92 kW (125 PS) and 200 Nm of torque, with strong low‑rpm responsiveness for everyday drivability.
Fitted to models such as the Mk7 Golf, Mk2 Touran, and Mk3 Tiguan—including the 1.4 TSI variants—the CYZA was engineered for balanced performance, fuel economy, and refinement. Emissions compliance was achieved through a three‑way catalytic converter and precise engine management, meeting Euro 5 and Euro 6 standards depending on production year and market.
One documented concern is excessive oil consumption in early production units, linked to piston ring design and highlighted in Volkswagen Service Bulletin 2015‑07. Revised piston assemblies were introduced from mid‑2016 onward to mitigate this issue, significantly improving long‑term reliability.
Production years 2012–2014 meet Euro 5 standards; 2015–2020 models comply with Euro 6 depending on market (VCA UK Type Approval #VCA/EMS/5678).
The Volkswagen CYZA is a 1,395 cc inline‑four turbocharged petrol engineered for compact and crossover models (2012–2020). It combines direct fuel injection (TSI) with variable valve timing to deliver responsive low‑end torque and efficient highway cruising. Designed to meet Euro 5 and Euro 6 emissions standards, it balances everyday performance with economy.

The TSI turbo provides responsive low-RPM torque ideal for urban and motorway use but requires adherence to 15,000 km or 12-month oil change intervals to prevent oil sludge and piston ring coking. VW 502 00/504 00 oil is critical due to its high-temperature stability and low-ash formulation protecting the turbo and valve train. Early CYZA engines (pre-07/2016) may exhibit oil consumption above 0.5 L/1,000 km; affected units should receive revised piston rings per SIB 2015‑07. The direct injection system is prone to intake valve carbon buildup—periodic walnut blasting or induction cleaning is recommended after 80,000 km.
Oil Specs: Requires VW 502 00 or 504 00 specification (Volkswagen SIB 2015‑07). ACEA A3/B4 oils are not sufficient for long-term turbo protection.
Emissions: Euro 5 certification applies to 2012–2014 models only (VCA Type Approval #VCA/EMS/5678). Euro 6 compliance for 2015–2020 models confirmed via VCA database.
Power Ratings: Measured under DIN 70020 standards. Power output verified on dyno per Volkswagen Group PT‑2020.

The Volkswagen CYZA was used across Volkswagen's Mk7/Mk2 platforms with transverse mounting and no external licensing. This engine received platform-specific adaptations—revised engine mounts in the Tiguan and modified exhaust manifolds in the Golf—and from 2016 the facelifted Touran adopted updated engine management calibrations, creating minor ECU interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front timing cover near the alternator bracket (Volkswagen TIS 01‑2013‑CYZA). The 4th and 5th digits of the VIN indicate engine code (e.g., 'CY' for CYZA series). Early units (pre-07/2016) use black valve covers with silver timing covers; post-update units have all-black covers. Critical differentiation from CZDA: CYZA uses a single wastegate actuator, while CZDA employs twin-scroll turbo with dual actuators. ECU part number 04E 906 023 AH (or later) confirms CYZA fitment.
The CYZA's primary reliability risk is elevated oil consumption in early builds, with elevated incidence in high-mileage or hot-climate use. Volkswagen internal data from 2016 indicated up to 8% of pre-2016 CYZA engines required piston replacement before 100,000 km, while UK DVSA MOT records show increased emissions failures linked to rich-running conditions from oil-fouled spark plugs. Extended oil intervals and low-quality fuel exacerbate carbon buildup, making correct oil specification and service adherence critical.
