The Volkswagen CHZL 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. In standard form it delivers 92 kW (125 PS) and 200 Nm of torque, with strong low‑rpm response for urban and motorway driving.
Fitted to models such as the Mk7 Golf, Mk2 Jetta, and Mk3 Touran—including the 1.4 TSI 125 PS variants—the CHZL was engineered for balanced perf…
Production years 2012–2014 meet Euro 5 standards; 2015–2019 models comply with Euro 6 depending on market .
The Volkswagen CHZL is a 1,395 cc inline‑four turbocharged petrol engineered for compact and MPV applications (2012–2019). It combines direct injection (TSI) with a single turbocharger to deliver responsive low‑end torque and smooth highway performance. Designed to meet Euro 5 (early) and Euro 6 (later) standards, it balances efficiency with everyday drivability.

The Volkswagen CHZL 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 Touran and updated cooling ducting in the Golf—and from 2016 the Golf Mk7.5 facelift adopted updated emissions hardware, creating minor ECU and sensor interchange limits. 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 CHZL is generally reliable if maintained properly. Early concerns around HPFP wear were addressed from 2016 with revised parts. Using correct VW 502 00/504 00 oil and adhering to 15,000 km service intervals greatly reduces risk. Well-maintained examples often exceed 200,000 km without major issues.
Most common issues are HPFP and cam follower wear, intake carbon buildup (due to direct injection), turbo actuator faults, and coolant flange leaks. These are documented in Volkswagen service bulletins, especially STB 2016‑07 for fuel system concerns.
The CHZL 1.4 TSI 125 PS appears in the Golf Mk7 (2012–2019), Jetta Mk2 (2013–2018), Touran Mk3 (2015–2019), and SEAT León Mk3 (2013–2016). All are transverse FWD applications with identical core architecture.
Aftermarket ECU tuning is common on the CHZL 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.
Real-world consumption is ~6.5 L/100km (city) and ~4.8 L/100km (highway), or ~52 mpg UK combined in a Golf. Mixed driving typically yields 48–55 mpg UK. Economy suffers if carbon buildup or HPFP issues develop.
Yes. The CHZL is an interference engine. If the timing chain fails (rare but possible), piston-to-valve contact can cause catastrophic damage. However, the chain is front-mounted and generally robust with proper oil maintenance.
Volkswagen specifies 5W‑30 or 5W‑40 synthetic oil meeting VW 502 00 or 504 00 standards. Using non-approved oil voids warranty and increases HPFP wear risk. Change every 15,000 km or annually.
