The Volkswagen CHZC is a 1,395 cc, inline‑four turbocharged petrol engine produced between 2012 and 2019. It features direct fuel injection (TSI), dual overhead camshafts (DOHC), and variable valve timing, delivering 110 kW (150 PS) and 250 Nm of torque. The integrated exhaust manifold enables faster warm‑up and reduced emissions.
Fitted to models such as the Mk7 Golf, Mk2 Touran, and B8 Passat, the CHZC was engineered for responsive performance and efficient cruising. Emissions compliance was achieved through a three‑way catalytic converter and precise lambda control, meeting Euro 5 and Euro 6 standards depending on production date.
One documented concern is high‑pressure fuel pump (HPFP) cam follower wear, noted in Volkswagen Service Bulletin 2015‑07. This issue stems from marginal lubrication under frequent short‑trip usage and suboptimal fuel quality. From mid‑2016, revised HPFP internals and updated camshaft lobe profiles were introduced to mitigate premature failure.
Production years 2012–2014 meet Euro 5 standards; 2015–2019 models comply with Euro 6 depending on market (VCA UK Type Approval #VCA/EMS/5679).
The Volkswagen CHZC is a 1,395 cc inline‑four turbocharged petrol engine engineered for compact and mid‑size models (2012–2019). It combines direct injection (TSI) with a single turbocharger to deliver strong low‑end torque and smooth high‑rpm power. Designed to meet Euro 5 and Euro 6 emissions standards, it balances performance with urban efficiency.

The TSI architecture provides strong low-RPM torque ideal for city driving but requires strict adherence to oil change intervals (every 15,000 km or annually) to protect the turbocharger and high-pressure fuel pump. VW 502 00/504 00 oil is critical due to its high thermal stability and detergency for direct-injection carbon control. Frequent short trips increase HPFP wear risk—Volkswagen recommends occasional extended drives above 2,000 rpm to maintain cam-follower lubrication. Post-2016 engines feature revised HPFP cam lobes per SIB 2015‑07.
Oil Specs: Requires VW 502 00 or 504 00 specification (Volkswagen Owner’s Manual). ACEA A3/B4 oils are acceptable only if VW-approved.
Emissions: Euro 5 certification applies to 2012–2014 models only (VCA Type Approval #VCA/EMS/5679). Euro 6 compliance confirmed for 2015–2019 builds.
Power Ratings: Measured under ISO 1585 standards. Power output assumes 95 RON fuel (Volkswagen Group PT‑2018).

ISO 1585: Road vehicles — Engine test code
The Volkswagen CHZC was used across Volkswagen's Mk7/B8 platforms with transverse mounting and no external licensing. This engine received platform-specific adaptations—shortened exhaust manifolds in the Touran and revised engine mounts in the Passat—and from 2016 the updated HPFP cam profile, 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 filler neck (Volkswagen ETKA CHZC‑1025). The 4th and 5th characters of the engine code on the V5C logbook should read 'CH'. Visual identification: CHZC uses a black plastic intake manifold with integrated charge air cooler and a single intercooler hose on the driver’s side. Differentiate from CHYB: CHZC produces 150 PS vs. 125 PS and features a higher-flow turbo actuator. HPFP cam lobes changed in 06/2016—verify part number 03C 101 031 E for updated units (Volkswagen SIB 2015‑07).
The CHZC's primary reliability risk is high-pressure fuel pump (HPFP) cam follower wear, with elevated incidence in urban stop-start use. Volkswagen internal data from 2016 indicated a measurable increase in HPFP-related warranty claims for vehicles under 60,000 km, while UK DVSA MOT records show low failure rates for emissions systems due to robust catalyst design. Short-trip driving and infrequent oil changes accelerate cam lobe wear, making extended warm-up cycles and correct oil specification critical.
