The Volkswagen CHZA is a 1,984 cc, inline‑four turbo‑charged petrol engine produced between 2012 and 2019. 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 performance variants including the Mk7 Golf R, Mk3 Scirocco R, and Audi S3 (8V), the CHZA was engineered for high‑performance dr…
Production years 2012–2014 meet Euro 5 standards; 2015–2019 models comply with Euro 6 .
The Volkswagen CHZA is a 1,984 cc inline‑four turbo‑charged petrol engine engineered for performance hatchbacks and coupes (2012–2019). It combines direct fuel injection (TSI) with a twin‑scroll turbocharger to deliver responsive power and strong mid‑range torque. Designed to meet Euro 5 and Euro 6 emissions standards, it balances track capability with daily drivability.

The Volkswagen CHZA was used across Volkswagen's Mk7 and Mk3 platforms with longitudinal mounting and shared with Audi under the VW Group modular strategy. This engine received platform-specific adaptations—reinforced mounts in the Golf R and modified cooling in the Scirocco R—and from 2016 the Golf R facelift adopted updated HPFP components, creating minor service part distinctions. All adaptations are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.
Analysis derived from manufacturer technical service bulletins and industry workshop records. Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The CHZA is generally robust when maintained properly. Early units (2012–2015) are prone to HPFP follower wear, but post‑2016 revisions improved durability. Using RON 98 fuel, correct oil (VW 502 00), and timely service greatly enhances longevity. Most issues stem from fuel quality or neglected maintenance.
Top issues include HPFP/cam follower wear, turbo wastegate rattle, PCV oil separator failure, and coolant flange leaks. These are documented in VW service bulletins. Carbon buildup is minimal due to direct injection, unlike older port-injected engines.
The CHZA powered the Mk7 Golf R (2013–2019), Mk3 Scirocco R (2012–2017), and was also used in the Audi S3 (8V, 2013–2016) under shared VW Group architecture. All are 2.0 TSI 220 PS applications with identical core architecture.
Aftermarket ECU tuning is common on the CHZA platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
In a Golf R, expect ~9.5 L/100km (city) and ~6.2 L/100km (highway), or ~36 mpg UK combined. Real-world mixed driving typically yields 32–38 mpg UK. Economy suffers noticeably with aggressive driving or poor fuel quality.
Yes. The CHZA 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 as lifetime; failures are usually due to external factors like oil starvation.
Volkswagen specifies 5W‑40 synthetic oil meeting VW 502 00 or 504 00 standards. Using non-approved oil risks sludge, HPFP wear, and VANOS issues. Change every 15,000 km or annually, whichever comes first.
Comprehensive technical documentation and regulatory references
EngineCode.uk is operated by Engine Finders UK Ltd. It provides engine-reference information and an optional commercial enquiry service. It is not an official manufacturer website. Check the record's sources and confirm vehicle-specific details before relying on it for parts, repairs or replacement.
Our editorial standard prioritises relevant manufacturer documentation and official regulatory sources. The sources and verification status for a record should be checked alongside the data.
A statement is not verified merely because a source is listed. Where supporting evidence is missing or conflicting, the record should identify that limitation. Please report unsupported or inconsistent information.
