The Volkswagen CCZA is a 1,968 cc, inline‑four turbo‑diesel engine produced between 2009 and 2015. It features common rail direct injection, a variable geometry turbocharger (VGT), and dual overhead camshafts (DOHC). In standard form it delivered 103 kW (140 PS) and 320 Nm of torque, engineered for responsive low‑rpm performance and highway efficiency.
Fitted to models such as the Golf VI, Jetta, Passat B6/B7, and Tiguan, the CCZA was engineered for drivers seeking a balance of fuel economy, strong low-end torque, and long-distance refinement. Emissions compliance was achieved through exhaust gas recirculation (EGR) and a diesel particulate filter (DPF), allowing Euro 5 compliance across all production years.
One documented concern is high-pressure fuel pump (HPFP) wear leading to loss of rail pressure and hard starts. This issue, highlighted in Volkswagen Service Bulletin 01‑12‑08, is often linked to insufficient lubricity in low-sulfur diesel or extended service intervals. From 2012, revised HPFP internals were introduced to improve durability.
All production years 2009–2015 meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/5678).
The Volkswagen CCZA is a 1,968 cc inline‑four turbo‑diesel engineered for compact and mid‑size models (2009–2015). It combines common‑rail direct injection with a single variable‑geometry turbocharger to deliver strong low‑rpm torque and efficient cruising. Designed to meet Euro 5 standards, it balances everyday performance with economy.

The VGT turbo provides strong low-RPM torque ideal for mixed driving but requires strict adherence to 15,000 km or 12-month oil change intervals using VW 507 00 oil to prevent HPFP and turbo wear. The Bosch CP4.2 pump is sensitive to fuel lubricity—only ultra-low-sulfur diesel (EN 590) should be used. Extended idling or frequent short trips accelerate DPF clogging and EGR carbon buildup. Pre-2012 HPFP units should be monitored for rail pressure faults; post-2012 revisions improve reliability per SIB 01 12 08.
Oil Specs: Requires VW 507 00 (5W-30) specification (Volkswagen SIB 01 12 08). Not interchangeable with 505 01 or 504 00.
Emissions: Euro 5 certification applies to all 2009–2015 models (VCA Type Approval #VCA/EMS/5678). No Euro 6 variants exist.
Power Ratings: Measured under DIN 70020 standards. Output stable across EU fuel quality bands (Volkswagen PT‑2020).

The Volkswagen CCZA was used across Volkswagen's Golf VI, Passat B6/B7, and Tiguan platforms with transverse mounting and shared with Škoda and SEAT under the MQB precursor architecture. This engine received platform-specific adaptations—revised engine mounts in the Passat and modified exhaust routing in the Tiguan—and from 2012 the Golf VI facelift adopted updated HPFP internals, creating minor interchange limits. Partnerships enabled Škoda Octavia and SEAT Exeo to use identical CCZA units. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front timing cover near the oil dipstick tube (Volkswagen Workshop Manual 1.968L TDI). The 4th and 5th digits of the engine code block (e.g., 'CCZA') confirm the variant. Visual cue: black plastic valve cover with 'TDI' logo. Critical differentiation from CAYC: CCZA uses Bosch CP4.2 HPFP with integrated pressure sensor; CAYC uses CP3. ECU part number 03L 907 551 F indicates CCZA. Pre-2012 HPFP (part 03L 130 106 B) is prone to wear; post-2012 uses revised 03L 130 106 D (Volkswagen SIB 01 12 08).
The CCZA's primary reliability risk is high-pressure fuel pump (HPFP) wear, with elevated incidence in vehicles using marginal-quality diesel or extended service intervals. Volkswagen internal data from 2013 indicated a measurable increase in HPFP replacements before 150,000 km in pre-2012 builds, while UK DVSA MOT records show DPF-related failures rising in urban-driven examples. Short-trip driving and infrequent oil changes accelerate EGR and turbo actuator issues, making fuel quality and maintenance adherence critical.
