The Volkswagen CZTA is a 1,984 cc, inline‑four turbocharged petrol engine produced between 2012 and 2019. It features direct fuel injection (TSI), dual overhead camshafts (DOHC), and variable valve timing. In standard form it delivers 162 kW (220 PS) and 350 Nm of torque, enabling brisk acceleration with everyday drivability.
Fitted to models such as the Mk7 Golf R, Audi S3 (8V), and Škoda Octavia vRS, the CZTA was engineered for high performance with daily usability. Emissions compliance was achieved through a combination of stratified lean-burn operation, precise cam phasing, and a close-coupled three-way catalytic converter, meeting Euro 6 standards across all production years.
One documented concern is high-pressure fuel pump (HPFP) wear, particularly in early-build units, highlighted in Volkswagen Group Service Bulletin 2015‑07‑01. This stems from inadequate lubrication under sustained high-load conditions. From mid‑2016, revised HPFP internals and updated camshaft lobe profiles were introduced to mitigate premature failure.
Volkswagen
All production years 2012–2019 meet Euro 6 emissions standards (VCA UK Type Approval #VCA/EMS/5678).
The Volkswagen CZTA is a 1,984 cc inline‑four turbocharged petrol engineered for performance hatchbacks and sedans (2012–2019). It combines direct injection (TSI) with a twin-scroll turbocharger to deliver strong mid-range torque and high-rev responsiveness. Designed to meet Euro 6 standards, it balances sporty performance with regulatory compliance.

The twin-scroll turbo and direct injection provide responsive power across a wide rev range but demand high-quality fuel (RON 98 recommended) and strict adherence to oil change intervals (every 15,000 km or annually). VW 502 00/504 00 oil is essential to protect the timing chain and high-pressure fuel pump cam lobe. Early CZTA engines (pre-07/2016) are prone to HPFP failure under aggressive driving; post-2016 units benefit from updated internals per VW SIB 2015‑07‑01. Carbon buildup on intake valves is minimal due to port-less direct injection but may still occur over 200,000 km.
Oil Specs: Requires VW 502 00 / 504 00 (5W-40) specification (VW Owner’s Manual Mk7 Golf R). Not interchangeable with Longlife-01.
Emissions: Euro 6 certification applies to all CZTA production years (VCA Type Approval #VCA/EMS/5678).
Power Ratings: Measured under ECE R85 standards. Peak output requires RON 98 fuel for full torque availability (VW TIS Doc. 06K‑10123).

The Volkswagen CZTA was used across Volkswagen Group's MQB and MQB-A1 platforms with transverse mounting and shared with Audi and Škoda. This engine received platform-specific adaptations—reinforced mounts in the Golf R, revised cooling in the Audi S3, and exhaust routing changes in the Octavia vRS—creating minor service part differences. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front timing cover near the oil filter housing (VW TIS 06K‑10123). The 7th VIN digit for Golf R is 'R'; for Audi S3 it is '8'. CZTA is visually distinguished by its black plastic intake manifold with integrated charge pipe and IHI IS20 turbo (silver housing with twin-scroll outlet). Critical differentiation from CAHA/CYVB/CZDB: CZTA uses Bosch HDEV5 injectors and lacks secondary air injection. HPFP part number 06K 127 025 E (pre-2016) vs. 06K 127 025 G (post-2016) indicates service bulletin compliance.
The CZTA's primary reliability risk is high-pressure fuel pump (HPFP) failure linked to camshaft lobe wear, with elevated incidence in track-driven or frequently high-load vehicles. VW internal field data from 2016 indicated a measurable uptick in HPFP replacements before 80,000 km in pre-mid-2016 builds, while UK DVSA records show no significant emissions-related MOT failures due to robust three-way catalyst design. Sustained high-RPM operation without adequate oil quality accelerates wear, making correct oil specification and driving pattern critical.
