The Volkswagen CJZB is a 1,395 cc, inline‑four turbocharged petrol engine produced between 2012 and 2016. It features direct fuel injection (TSI), dual overhead camshafts (DOHC), and variable valve timing, delivering 92 kW (125 PS) and 200 Nm of torque. The compact design integrates the exhaust manifold into the cylinder head, enabling rapid warm‑up and consistent low‑end response.
Fitted to models such as the Mk7 Golf, Mk2 Touran, and SEAT León (5F), the CJZB was engineered for urban efficiency and responsive daily driving. Emissions compliance was achieved through precise direct injection and a close‑coupled three‑way catalytic converter, meeting Euro 5b standards across all production years.
One documented concern is premature wear of the high‑pressure fuel pump (HPFP) cam follower, highlighted in Volkswagen Service Technical Bulletin 2013‑12. This issue arises from marginal lubrication under frequent short‑trip conditions. From late 2014, revised cam follower materials and updated HPFP designs were introduced to improve durability.
All CJZB production years (2012–2016) meet Euro 5b emissions standards (VCA UK Type Approval #VCA/EMS/7890).
The Volkswagen CJZB is a 1,395 cc inline‑four turbocharged petrol engine engineered for compact hatchbacks and MPVs (2012–2016). It combines gasoline direct injection with a single turbocharger to deliver responsive low‑end torque and urban efficiency. Designed to meet Euro 5b standards, it balances fuel economy with drivability.

The CJZB provides brisk low-RPM torque ideal for city driving but requires high-quality fuel (RON 95 minimum, RON 98 recommended) and strict adherence to oil change intervals (every 15,000 km or annually) to protect the turbo and HPFP. VW 502 00/505 00 oil is essential due to its high thermal stability and compatibility with the timing chain tensioner. Early HPFP failures are linked to short-trip driving and low-lubricity fuel; post-2014 engines include an upgraded cam follower per SIB 2013‑12. Carbon buildup on intake valves is minimal due to direct injection, but occasional decarbonisation may be needed after 100,000 km.
Oil Specs: Requires VW 502 00 or 505 00 specification (Volkswagen Owner’s Manual CJZB). Not compatible with Longlife‑04 or ACEA C3 oils.
Emissions: Euro 5b certification applies to all CJZB models (2012–2016) (VCA Type Approval #VCA/EMS/7890). No Euro 6 variants exist.
Power Ratings: Measured under DIN 70020 standards. Full 125 PS output requires RON 95 fuel (Volkswagen TIS Doc. 04E‑2035).

The Volkswagen CJZB was used across Volkswagen's Mk7 and MPV platforms with transverse mounting and shared within the Volkswagen Group. This engine received platform-specific calibrations—revised cooling in the Touran and sportier mapping in the SEAT León—and from 2015 the EA211 Gen 2 transition began, creating clear generational boundaries. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front timing cover near the oil filter housing (Volkswagen TIS 04E‑1010). The 4th–6th characters of the engine code on the VIN plate (e.g., “CJZ”) confirm family; full code “CJZB” appears on the build sticker in the service book or spare wheel well. Visual cue: black plastic intake manifold with “TSI” logo and integrated charge air cooler. Critical differentiation from CZDA/CZEA: CJZB uses a single Honeywell GT12 turbo with specific wastegate actuator (part #04E 145 701 A). HPFP cam follower must match production date—pre-10/2014 units require updated follower per SIB 2013‑12.
The CJZB's primary reliability risk is high-pressure fuel pump (HPFP) cam follower wear in early builds, with elevated incidence in urban or short-trip usage. Volkswagen internal data (2014) indicated a notable rate of HPFP replacements before 80,000 km in pre-2014 units, while UK DVSA MOT records show minor turbo actuator faults as a secondary concern. Extended oil intervals and low-quality fuel increase HPFP and turbo stress, making fuel specification and service adherence critical.
