The Volkswagen CJKA 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 delivered 92 kW (125 PS) and 200 Nm of torque, enabling brisk low‑rpm response and efficient urban driving.
Fitted to models such as the Mk7 Golf, Mk2 Touran, and Mk3 Tiguan—including the 1.4 TSI variants—the CJKA was engineered for responsive perf…
Production years 2012–2014 meet Euro 5 standards; 2015–2019 models meet Euro 6 depending on market .
The Volkswagen CJKA is a 1,395 cc inline‑four turbocharged petrol engineered for compact and crossover models (2012–2019). It combines direct fuel injection (TSI) with variable valve timing to deliver responsive 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 Volkswagen CJKA was used across Volkswagen's Mk7/Mk2 platforms with transverse mounting and shared with SEAT and Škoda under the MQB architecture. This engine received platform-specific adaptations—revised engine mounts in the Tiguan and modified cooling ducts in the Golf—and from 2016 the facelifted Touran adopted updated PCV routing, creating minor interchange limits. Partnerships enabled SEAT Leon and Škoda Octavia to use near-identical variants. 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 CJKA offers strong performance and efficiency, but is prone to intake valve coking due to direct injection only. Early models (2012–2015) are more susceptible; post-2016 revisions improved PCV design. With regular oil changes, longer drives, and updated PCV hardware, it can be dependable beyond 200,000 km.
Top issues include intake valve carbon buildup, PCV/oil separator failure, high-pressure fuel pump wear, and coolant flange leaks. These are documented in Volkswagen SIB 2015-08 and recurring workshop reports. Most are preventable with proper maintenance and updated components.
The CJKA powered the Golf VII (1.4 TSI 125 PS), Touran II (2015+), and Tiguan II (2016+). It was also used in SEAT Leon Mk3 and Škoda Octavia III under engine codes CZDA/CJKA. All are MQB-platform vehicles with transverse engine mounting and Euro 5/6 compliance.
Aftermarket ECU tuning is common on the CJKA 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 125 PS, real-world consumption is ~6.8 L/100km (city) and ~4.9 L/100km (highway), or ~42 mpg UK combined. With conservative driving, 45–50 mpg UK is achievable. Economy suffers if intake coking or PCV issues are present.
Yes. The CJKA 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 maintenance-free; failures are uncommon if oil is changed regularly.
Volkswagen specifies 5W‑30 or 5W‑40 synthetic oil meeting VW 502 00 or 504 00 standards. Always use oil approved for TSI engines and change every 15,000 km or annually to protect the turbo, fuel pump cam follower, and timing components.
