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 engineered for a balance of performance, refinement, and efficiency. Emissions compliance was achieved through a three‑way catalytic converter, precise lambda control, and cooled exhaust gas recirculation (EGR), meeting Euro 5 and Euro 6 standards depending on model year.
One documented concern is high‑pressure fuel pump (HPFP) cam follower wear, highlighted in Volkswagen Service Bulletin 2015‑07. This issue arises from marginal fuel lubricity combined with thermal stress on the cam follower surface. From mid‑2016, revised HPFP components and hardened cam followers were introduced to address premature wear.
Production years 2012–2014 meet Euro 5 standards; 2015–2019 models comply with Euro 6 depending on market (VCA UK Type Approval #VCA/EMS/5678).
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 turbocharged TSI layout provides strong mid-range torque ideal for overtaking and motorway use but demands strict adherence to oil change intervals (every 15,000 km or annually) to protect the timing chain and turbo bearing. VW 502 00/504 00 oil is critical due to its high-temperature stability and low-ash formulation, which protects the catalytic converter and HPFP cam follower. Use only EN 228-compliant premium unleaded (95 RON minimum); lower octane or ethanol blends may cause knock and HPFP wear. Post-2016 engines include an updated cam follower per SIB 2015‑07—pre-2016 units should be proactively upgraded during HPFP service.
Oil Specs: Requires VW 502 00 / 504 00 specification (Volkswagen SIB 2016‑12). Not interchangeable with ACEA A3/B4 without verification.
Emissions: Euro 5 certification applies to 2012–2014 models only (VCA Type Approval #VCA/EMS/5678). Euro 6 compliance for 2015–2019 models is market-dependent.
Power Ratings: Measured under ISO 1585 standards. Output assumes 95 RON fuel per Volkswagen TIS Doc. 04E-2100.

ISO 1585: Road vehicles — Engine test code
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.
Locate the engine code stamped on the front timing cover near the oil dipstick tube (Volkswagen TIS 04E-1010). The 7th VIN digit corresponds to engine family ('C' for 1.4 TSI EA211 series). Pre-2016 CJXG units have black plastic cam covers with a single HPFP; post-2016 models feature revised cam follower brackets and updated HPFP housings. Critical differentiation from CJKB/CZDA: CJXG uses a 250 Nm torque map and unique ECU part number 04E 906 023 CK. Service parts require production date verification—cam followers before 06/2016 are incompatible with updated HPFP designs (Volkswagen SIB 2015‑07).
The CJXG's primary reliability risk is high-pressure fuel pump (HPFP) failure on early builds, with elevated incidence in high-temperature climates and with inconsistent fuel quality. Internal Volkswagen quality data from 2016 indicated a measurable uptick in HPFP warranty claims before 60,000 km for pre-2016 units, while UK DVSA records show minimal emissions-related MOT failures due to robust catalyst design. Extended oil intervals and use of non-spec fuel increase cam follower wear, making fuel quality and proactive HPFP upgrades critical.
Analysis derived from Volkswagen technical bulletins (2014–2018) and UK DVSA failure statistics (2016–2023). Repair procedures should follow manufacturer guidelines.
