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 perfor…
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 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.
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.

The most common questions about engine codes, what they mean, how to find them and how this database works
The CYZA is generally reliable when properly maintained, but early units (2012–mid-2016) are prone to oil consumption due to piston design. Post-2016 revisions resolved this. Using correct VW 502 00/504 00 oil and adhering to service intervals greatly improves longevity.
Top issues include excessive oil consumption (early engines), intake valve carbon buildup, turbo wastegate rattle, and plastic coolant flange leaks. These are documented in Volkswagen service bulletins and addressed with updated OEM parts.
The CYZA appears in the Golf VII (2012–2020), Touran II (2015–2020), Tiguan II (2016–2020), and Passat B8 (2015–2018), all as the 1.4 TSI 125 PS variant. It is not used in SEAT, Škoda, or Audi under this code.
Yes. Stage 1 ECU remaps typically yield +20–25 kW (150–160 PS) safely on stock internals. The turbo and fuel system support modest gains, but aggressive tuning without upgraded intercooler or injectors risks long-term reliability.
In a Golf 1.4 TSI, expect ~6.2 L/100km (city) and ~4.5 L/100km (highway), or ~47 mpg UK combined. Real-world mixed driving typically returns 42–50 mpg (UK), depending on conditions and maintenance.
Yes. The CYZA is an interference engine. If the timing chain fails (rare but possible), piston-to-valve contact can cause catastrophic damage. However, the chain is designed for life and rarely fails if oil is maintained.
Volkswagen specifies 5W‑30 or 5W‑40 synthetic oil meeting VW 502 00 or 504 00 standards. Never use non-approved oils, as they lack the high-temperature stability needed for turbo and piston protection.
