The Volkswagen CJXG 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 110 kW (150 PS) and 250 Nm of torque, with strong mid‑range responsiveness suitable for compact and mid‑size applications.
Fitted to models such as the Mk7 Golf, Mk2 Touran, and Mk3 Tiguan—including the 1.4 TSI 150 PS variants—the CJXG was…
Production years 2012–2014 meet Euro 5 standards; 2015–2019 models comply with Euro 6 depending on market .
The Volkswagen CJXG 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 responsive mid‑range torque and efficient highway cruising. Designed to meet Euro 5 and Euro 6 emissions standards, it balances performance with regulatory compliance.

The Volkswagen CJXG was used across Volkswagen's Mk7/Mk2 platforms with transverse mounting and no external licensing. This engine received platform-specific adaptations—reinforced mounts in the Tiguan and revised cooling routing in the Golf—and from 2016 the MQB facelift models 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.

The most common questions about engine codes, what they mean, how to find them and how this database works
The CJXG offers strong performance and good efficiency, but early models (2012–2015) had HPFP reliability concerns. Post-2016 revisions significantly improved fuel system durability. With proper maintenance—especially using correct oil and quality fuel—well-cared-for examples can exceed 200,000 km without major issues.
Top issues include HPFP failure due to cam follower wear, turbo wastegate rattle, carbon buildup on intake valves (common to all direct-injection engines), and coolant flange leaks. These are documented in Volkswagen service bulletins, particularly SIB 2015‑07 for the HPFP concern.
The CJXG 1.4 TSI 150 PS was used in the Golf VII (2012–2019), Touran II (2015–2019), Tiguan II (2016–2019), and limited Passat B8 markets (2015–2018). All applications are transverse-mounted and part of the EA211 engine family.
Aftermarket ECU tuning is common on the CJXG 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 1.4 TSI 150 PS, expect ~6.8 L/100km (city) and ~4.9 L/100km (highway), or about 48 mpg UK combined. Real-world mixed driving typically returns 44–50 mpg (UK), depending on conditions and maintenance status.
Yes. The CJXG is an interference engine. If the timing chain fails (rare but possible), piston-to-valve contact can cause catastrophic damage. While the chain is designed as maintenance-free, any unusual noise warrants immediate inspection.
Volkswagen specifies 5W‑30 or 5W‑40 synthetic oil meeting VW 502 00 or 504 00 standards. Always use manufacturer-approved oil and adhere to 15,000 km or annual change intervals to protect the turbo, chain, and emissions systems.
