The Volkswagen CJXB is a 1,984 cc, inline‑four turbocharged petrol engine produced between 2012 and 2015. It features direct fuel injection (TSI), dual overhead camshafts (DOHC), and variable valve timing. In standard form it delivered 162 kW (220 PS) and 350 Nm of torque, enabling sporty performance with improved fuel economy over prior naturally aspirated units.
Fitted to models such as the Golf Mk7 GTI, Passat B7, and Tiguan, the CJXB was engineered for responsive performance and everyday usability. Emissions compliance was achieved through precise direct injection, exhaust gas recirculation (EGR), and a close-coupled catalytic converter, meeting Euro 5b standards across all production years.
One documented concern is high-pressure fuel pump (HPFP) wear under sustained high-load conditions, highlighted in Volkswagen Service Technical Bulletin 2013‑12. This issue stems from marginal lubrication of the cam follower interface in early HPFP designs. Revised HPFP units with hardened cam followers were introduced from mid‑2013 onward.
All production years 2012–2015 meet Euro 5b standards (VCA UK Type Approval #VCA/EMS/7892).
The Volkswagen CJXB is a 1,984 cc inline‑four turbocharged petrol engineered for compact and mid‑size models (2012–2015). It combines gasoline direct injection with a single turbocharger to deliver responsive performance and strong mid‑range torque. Designed to meet Euro 5b emissions standards, it balances sporty driving dynamics with reasonable fuel economy.

The TSI architecture delivers strong mid-range torque and responsive throttle but demands strict adherence to oil change intervals (every 15,000 km or annually) using VW 502 00/504 00 oil to protect the turbo and timing chain. The high-pressure fuel pump requires consistent use of high-quality 95+ RON unleaded fuel to prevent premature wear. Carbon buildup on intake valves (due to lack of fuel washing in direct-injection systems) may require walnut blasting after 80,000–100,000 km. Early CJXB units (pre-mid-2013) should be inspected for HPFP cam follower wear per VW STB 2013‑12.
Oil Specs: Requires VW 502 00 or 504 00 specification (Volkswagen Owner’s Manual CJXB). ACEA A3/B4 oils are acceptable only if VW-approved.
Emissions: Euro 5b certification applies to all CJXB production years (VCA Type Approval #VCA/EMS/7892).
Power Ratings: Measured under ISO 1585 standards. Output assumes 95 RON fuel (Volkswagen Group PT‑2013).

The Volkswagen CJXB was used across Volkswagen's A6/B7/5N platforms with transverse mounting and shared with Škoda and SEAT under the VAG group. This engine received platform-specific adaptations—reinforced mounts in the Passat B7 and revised cooling in the Tiguan—and from 2014 the updated Golf Mk7 retained the CJXB while later models transitioned to EA888 Gen 3B. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front timing cover near the oil filter housing (Volkswagen ETKA 06K‑902). The 4th and 5th characters of the engine code on the VIN plate (e.g., “CJXB”) confirm identity. Visual cues: black plastic cam cover with “TSI” logo, K04 turbo with integrated exhaust manifold. Differentiate from CJ by power output (220 PS vs. 200 PS) and HPFP part number (06F 127 025 G for CJXB). Pre-mid-2013 HPFP units are prone to cam follower wear; verify replacement status via service history or STB 2013‑12 inspection.
The CJXB's primary reliability risk is high-pressure fuel pump (HPFP) cam follower wear on early builds, with elevated incidence in high-mileage or track-use applications. Volkswagen internal field data from 2014 indicated a notable rate of HPFP-related repairs before 100,000 km, while UK DVSA records show secondary issues with carbon buildup on intake valves in direct-injection TSI engines. Extended oil intervals and inconsistent fuel quality accelerate wear, making oil/fuel quality and service adherence critical.
Analysis derived from Volkswagen technical bulletins (2012–2015) and UK DVSA failure statistics (2015–2023). Repair procedures should follow manufacturer guidelines.
