The Volkswagen CJXC is a 1,984 cc, inline‑four turbocharged direct-injection petrol engine produced between 2010 and 2014. It features DOHC, 16 valves, and a single turbocharger with air-to-air intercooler, delivering 155 kW (211 PS) and 280 Nm of torque. This engine employs Volkswagen’s TSI technology, combining high-pressure direct fuel injection with turbocharging to provide responsive performance and improved fuel efficiency.
Fitted to performance-oriented models such as the Golf VI R, Scirocco R, and Passat CC R-Line, the CJXC was engineered for dynamic handling and high-speed stability. Emissions compliance was achieved through a three-way catalytic converter and precise engine management, meeting Euro 5 standards across all markets.
One documented concern is high-pressure fuel pump (HPFP) wear under sustained high-load conditions, highlighted in Volkswagen Service Bulletin 2012‑03‑08. This issue stems from marginal lubrication during extended high-RPM operation, particularly when using non-specified fuel or exceeding recommended oil change intervals. From mid-2012, revised HPFP cam followers and internal clearances were introduced to enhance durability.
Production years 2010–2014 meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/6789).
The Volkswagen CJXC is a 1,984 cc inline‑four turbocharged petrol engine engineered for high-performance compact and mid-size models (2010–2014). It combines direct fuel injection with a single turbocharger to deliver brisk acceleration and stable high-speed cruising. Designed to meet Euro 5 emissions standards, it balances sporty output with regulated efficiency.

The CJXC’s turbocharged direct injection provides strong mid-range thrust and refined high-RPM response, ideal for spirited driving. However, the high-pressure fuel pump requires consistent use of 95 RON (or higher) unleaded petrol and strict adherence to 10,000–15,000 km oil change intervals to prevent premature wear. VW 502 00/504 00 oil is essential to protect the turbo bearing and chain system. Extended idling or frequent short trips may lead to carbon buildup on intake valves due to lack of fuel-wash effect. Revised HPFP units (from mid-2012) improve reliability; pre-mid-2012 engines should be monitored for fuel rail pressure faults per VW SIB 2012‑03‑08.
Oil Specs: Requires VW 502 00 or 504 00 specification (Volkswagen SIB 2012‑03‑08). ACEA A3/B4 oils are acceptable only if VW-approved.
Emissions: Euro 5 certification applies to all CJXC engines (2010–2014) (VCA Type Approval #VCA/EMS/6789). No Euro 6 variants exist.
Power Ratings: Measured under DIN 70020 standards. Full 211 PS output requires 98 RON fuel for optimal knock resistance (Volkswagen TIS Doc. 06K‑2010).

The Volkswagen CJXC was used across Volkswagen's Golf VI, Scirocco, and Passat CC platforms with transverse mounting and no external licensing. This engine received platform-specific adaptations—reinforced engine mounts in the Golf R and enhanced oil cooling in the Scirocco R—and from mid-2012 the Passat CC R-Line received updated HPFP hardware, creating minor interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front timing cover near the oil filler neck (Volkswagen TIS 06K‑1005). The 4th–6th digits of the VIN indicate engine code (e.g., 'CJX' for CJXC). Visual identification: black plastic valve cover with 'TSI' logo; intake manifold with integrated charge pipe. Critical differentiation from CJAA/CAEB: CJXC uses higher-flow injectors, stiffer valve springs, and a modified cam profile for 211 PS output. Pre-mid-2012 HPFP units (part no. 06F 127 025 B) are not interchangeable with post-mid-2012 revisions (06F 127 025 E) due to internal cam follower redesign (Volkswagen SIB 2012‑03‑08).
The CJXC's primary reliability risk is high-pressure fuel pump (HPFP) wear on early builds, with elevated incidence in sustained high-load or track use. Volkswagen internal data from 2013 indicated a notable rate of HPFP replacement before 85,000 km in pre-mid-2012 units, while UK DVSA MOT records show minimal emissions-related failures due to robust catalytic converter design. Extended oil intervals and low-octane fuel increase HPFP stress, making fuel quality and maintenance adherence critical.
