The Volkswagen CCZC is a 1,968 cc, inline‑four turbo‑charged diesel engine produced between 2015 and 2020. It features common-rail direct injection, a variable geometry turbocharger (VGT), dual overhead camshafts (DOHC), and a diesel particulate filter (DPF). In standard form it delivers 110 kW (150 PS) and 340 Nm of torque, with strong low‑rpm pull ideal for urban and motorway driving.
Fitted to models such as the Mk7 Golf, Mk2 Tiguan, and Mk3 Passat—including the 2.0 TDI variants—the CCZC was engineered for responsive torque delivery and compliance with stringent emissions standards. Emissions control is achieved through cooled exhaust gas recirculation (EGR), a DPF, and selective catalytic reduction (SCR) with AdBlue injection, enabling compliance with Euro 6b and later Euro 6d-TEMP standards depending on model year and market.
One documented concern is injector coking and carbon buildup in the intake tract, highlighted in Volkswagen Service Technical Bulletin 2017‑12. This stems from crankcase ventilation (CCV) oil vapour mixing with recirculated exhaust gases, leading to reduced airflow and rough idling. From 2018, revised injector calibrations and updated EGR coolers were introduced to mitigate deposit formation and improve cold-start emissions.
Production years 2015–2017 meet Euro 6b standards; 2018–2020 models meet Euro 6d-TEMP compliance depending on market (VCA UK Type Approval #VCA/EMS/7890).
The Volkswagen CCZC is a 1,968 cc inline‑four turbo‑diesel engineered for compact and mid‑size models (2015–2020). It combines Bosch CRS3 common‑rail injection with a single variable‑geometry turbocharger to deliver strong low‑rpm torque and efficient cruising. Designed to meet Euro 6b and Euro 6d-TEMP standards, it balances performance with urban emissions compliance.

The VGT turbo and common-rail system provide strong low-end torque but require strict adherence to 15,000 km oil change intervals using VW 507 00 oil to protect the high-pressure fuel pump and timing chain. Extended idling or short urban trips accelerate carbon buildup in the EGR and intake manifold. AdBlue system integrity is critical—low-quality DEF or empty tanks trigger limp mode and may disable restart. Post-2018 models feature updated injector spray patterns and EGR coolers per VW SIB 2017-12 to reduce coking. Fuel must meet EN 590 standards; biodiesel blends above B7 are not approved.
Oil Specs: Requires VW 507 00 specification (VW SIB 2017-12). Not compatible with ACEA C3 unless explicitly approved for diesel particulate filter systems.
Emissions: Euro 6b certification applies to 2015–2017 models only (VCA Type Approval #VCA/EMS/7890). Euro 6d-TEMP compliance confirmed for 2018–2020 builds.
Power Ratings: Measured under ISO 1585 standards. Power output assumes EN 590-compliant diesel with ≤10 ppm sulfur (VW TIS Doc. 04L-3001).

ISO 1585: Road vehicles — Engine test code
The Volkswagen CCZC was used across Volkswagen's Mk7/Mk2 platforms with transverse mounting and shared with Škoda and SEAT under the MQB architecture. This engine received platform-specific adaptations—revised cooling ducts in the Tiguan and acoustic shielding in the Golf—and from 2018 the facelifted Passat B8.5 adopted updated AdBlue tank routing and ECU calibrations, creating minor interchange limits. Partnerships enabled Škoda Superb and SEAT Ateca to use identical CCZC units. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front timing cover near the oil filler neck (VW TIS 04L-0010). The 4th and 5th digits of the engine code on the VIN plate (e.g., 'CZ') correspond to the CCZC family. Pre-2018 units have black plastic intake manifolds with single EGR cooler; post-2018 models use dual-stage EGR coolers and revised injector nozzles. Critical differentiation from CRLB/CRKB: CCZC uses Bosch EDC17CP44 ECU with AdBlue dosing, while earlier variants lack SCR. Service parts require production date verification—intake manifolds before 01/2018 are incompatible with later emissions calibrations (VW SIB 2017-12).
The CCZC's primary reliability risk is injector coking and EGR fouling, with elevated incidence in short-trip urban use. Internal VW quality data from 2019 indicated a significant portion of pre-2018 engines required injector cleaning before 100,000 km, while UK DVSA MOT records show increased AdBlue-related failures in vehicles with neglected DEF systems. Frequent cold starts and extended idling accelerate deposit formation, making driving pattern and fluid maintenance critical.
Analysis derived from Volkswagen technical bulletins (2015–2020) and UK DVSA failure statistics (2017–2023). Repair procedures should follow manufacturer guidelines.
