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 everyday usability. Emissions compliance was achieved through a combination of three‑way catalytic converter, secondary air injection, and precise lambda control, meeting Euro 6 standards from launch.
One documented concern is high‑pressure fuel pump (HPFP) wear leading to hard starts or misfires, highlighted in Volkswagen Service Technical Bulletin 2017‑08‑01. This issue is often linked to prolonged use of non‑specification fuel or extended service intervals. From mid‑2018, revised HPFP components were introduced to improve durability.
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 CHZK delivers brisk acceleration and flat torque, ideal for both urban and motorway use, but requires strict adherence to 15,000 km or 12‑month oil change intervals using VW 504 00/507 00 oil to protect turbo and timing components. The Bosch HDP5 high-pressure fuel pump is sensitive to low-quality fuel; only EN 228‑compliant RON 95+ petrol should be used. Carbon buildup on intake valves is minimal due to direct injection, but occasional decarbonisation may be needed after 100,000 km. HPFP failures noted in early builds (pre‑06/2018) are addressed by updated parts per VW SIB 2017‑08‑01.
Oil Specs: Requires VW 504 00 / 507 00 (5W‑30) specification (Volkswagen Owner’s Manual 2016).
Emissions: Euro 6 certification applies to all CHZK production (2015–2020) (VCA Type Approval #VCA/EMS/5678).
Power Ratings: Measured under ISO 1585 standards. Peak output requires RON 98 fuel for optimal knock control (VW TIS Doc. 01‑2015‑CHZK).

ISO 1585: Road vehicles — Engine test code
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.
Locate the engine code stamped on the front timing cover near the oil filter housing (VW TIS 01‑2015‑CHZK). The 7th VIN digit is 'C' for CHZK-equipped vehicles. Visual identification: black plastic cam cover with 'TSI 220' badge. Critical differentiation from CAHA/CZDA: CHZK uses IHI VF39 turbo with integrated exhaust manifold and Bosch HDP5 fuel pump. HPFP part number 06K 127 025 D (pre‑06/2018) vs. 06K 127 025 F (post‑update) per VW SIB 2017‑08‑01.
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.
Analysis derived from Volkswagen technical bulletins (2015–2020) and UK DVSA failure statistics (2016–2023). Repair procedures should follow manufacturer guidelines.
