The Volkswagen CHZK is a 1,984 cc, inline‑four turbo‑charged petrol engine produced between 2015 and 2020. It features direct fuel injection (TSI), dual overhead camshafts (DOHC), and variable valve timing, delivering 162 kW (220 PS) and 350 Nm of torque. The integrated exhaust manifold enables faster warm‑up and reduced emissions.
Fitted to models such as the Golf Mk7 GTI Performance, Tiguan Mk2, and Passat B8, the CHZK was engineered for responsive performance and ev…
All production years 2015–2020 meet Euro 6 emissions standards (VCA UK Type Approval #VCA/EMS/5678).
The Volkswagen CHZK is a 1,984 cc inline‑four turbo‑charged petrol engineered for compact and mid‑size performance models (2015–2020). It combines direct injection (TSI) with variable valve timing to deliver responsive power and smooth torque delivery. Designed to meet Euro 6 standards from launch, it balances sporty driving dynamics with regulatory compliance.

The Volkswagen CHZK was used across Volkswagen's Mk7/B8 platforms with transverse mounting and no external licensing. This engine received platform-specific adaptations—reinforced mounts in the Tiguan and performance cooling in the Golf GTI Performance—and from mid‑2018 the Passat received updated HPFP hardware, creating minor service part distinctions. All adaptations are documented in OEM technical bulletins.
The CHZK's primary reliability risk is high-pressure fuel pump (HPFP) wear in early production units, with elevated incidence in vehicles using non-premium fuel or exceeding service intervals. VW internal data from 2018 indicated a measurable uptick in HPFP-related warranty claims before 100,000 km for pre‑mid‑2018 builds, while UK DVSA MOT data shows low emissions failure rates due to robust Euro 6 compliance. Fuel quality and oil change discipline make long-term reliability highly dependent on owner maintenance habits.

The most common questions about engine codes, what they mean, how to find them and how this database works
The CHZK is generally robust when maintained properly. Early units (2015–mid-2018) had HPFP concerns, but post-update engines are more durable. Using RON 98 fuel and adhering to 15,000 km oil changes with VW 504 00/507 00 spec oil significantly improves longevity. The timing chain is maintenance-free and rarely problematic.
Most documented issues are HPFP wear (pre‑2018), turbo actuator faults, PCV diaphragm rupture, and coolant flange leaks. These are covered in VW service bulletins. Carbon buildup is minimal due to direct injection, unlike earlier FSI engines.
The CHZK powered the Golf Mk7 GTI Performance (220 PS), Tiguan Mk2 (2.0 TSI 220 PS 4Motion), and Passat B8 (2.0 TSI 220 PS) from 2015 to 2020. It was not used in SEAT, Škoda, or Audi under this code—those brands used related but distinct EA888 Gen 3 variants.
Yes. The CHZK responds well to ECU remapping, typically gaining +30–50 kW on stage 1 with stock hardware. The IHI VF39 turbo and internals support up to ~280–300 PS reliably. Supporting mods (intercooler, exhaust, fueling) are recommended for higher stages. Always use high-octane fuel post-tune.
In a Golf GTI Performance, expect ~8.5 L/100km (city) and ~5.8 L/100km (highway), or ~40 mpg UK combined. The Tiguan 4Motion is slightly thirstier at ~9.2 L/100km city. Real-world economy depends heavily on driving style—aggressive use can push consumption above 11 L/100km.
Yes. Like all modern VW TSI engines, the CHZK is an interference design. If the timing chain fails (extremely rare), piston-to-valve contact will cause catastrophic damage. However, the chain is front-mounted and designed for life-of-engine use with proper oil maintenance.
Volkswagen specifies SAE 5W‑30 oil meeting VW 504 00 (petrol) or 507 00 (diesel-compatible) standards. Always use fully synthetic oil approved to these specs and change every 15,000 km or 12 months to protect the turbo, HPFP, and timing system.
