The Volkswagen CKTC is a 1,498 cc, inline‑four turbo‑charged petrol engine produced between 2016 and 2023. It features direct fuel injection (TSI), dual overhead camshafts (DOHC), and variable valve timing, delivering 110 kW (150 PS) and 250 Nm of torque. The compact aluminium block with integrated exhaust manifold enables rapid warm‑up and reduced emissions.
Fitted to models such as the Golf Mk7.5, T-Roc, and Škoda Karoq, the CKTC was engineered for responsive urban performance and efficient motorway cruising. Emissions compliance was achieved through a three‑way catalytic converter, secondary air injection, and precise lambda control, meeting Euro 6b standards from launch.
One documented concern is premature wear of the high-pressure fuel pump (HPFP) drive lobe on the intake camshaft, potentially causing fuel pressure loss and misfires. This issue, highlighted in Volkswagen Service Technical Bulletin 2019‑04‑05, is linked to marginal lubrication under high thermal load in early production units. From mid‑2020, revised camshaft metallurgy and HPFP design were introduced to improve durability.
All production years 2016–2023 meet Euro 6b emissions standards (VCA UK Type Approval #VCA/EMS/9215).
The Volkswagen CKTC is a 1,498 cc inline‑four turbo‑charged petrol engineered for compact and subcompact SUVs and hatchbacks (2016–2023). It combines direct injection (TSI) with variable valve timing to deliver responsive low-end torque and smooth power delivery. Designed to meet Euro 6b standards from launch, it balances performance with stringent emissions compliance.

The CKTC delivers brisk low-end response ideal for city and highway use but requires strict adherence to 15,000 km or 12-month oil change intervals using VW 504 00/507 00 oil to protect the turbo, HPFP, and camshaft drive lobes. The Bosch HDP6 high-pressure fuel pump demands EN 228-compliant RON 95+ petrol; low-quality fuel accelerates cam lobe wear. Early units (pre-06/2020) are susceptible to HPFP drive lobe degradation—addressed by updated camshafts per VW SIB 2019‑04‑05. Carbon buildup on intake valves is minimal due to direct injection, though occasional decarbonisation may be beneficial after 100,000 km.
Oil Specs: Requires VW 504 00 / 507 00 (5W‑30) specification (Volkswagen Owner’s Manual 2017).
Emissions: Euro 6b certification applies to all CKTC production (2016–2023) (VCA Type Approval #VCA/EMS/9215).
Power Ratings: Measured under ISO 1585 standards. Peak output assumes RON 95 fuel; RON 98 improves knock margin (VW TIS Doc. 01‑2016‑CKTC).

The Volkswagen CKTC was used across Volkswagen's Mk7.5/AQ platforms with transverse mounting and no external licensing. This engine received platform-specific adaptations—reinforced mounts in the T-Roc and revised intake routing in the Golf—and from mid‑2020 the Karoq received updated camshaft hardware, creating minor service part distinctions. 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 01‑2016‑CKTC). The 7th VIN digit is 'C' for CKTC-equipped vehicles. Visual identification: black plastic cam cover with 'TSI 150' badge. Critical differentiation from CZDA/DPCA: CKTC uses Honeywell TD025 turbo with integrated exhaust manifold and Bosch HDP6 fuel pump. Camshaft part number 04E 109 021 A (pre‑06/2020) vs. 04E 109 021 C (post‑update) per VW SIB 2019‑04‑05.
The CKTC's primary reliability risk is HPFP drive lobe wear on the intake camshaft in early production units, with elevated incidence in vehicles using non-premium fuel or exceeding service intervals. VW internal data from 2020 indicated a measurable uptick in cam-related warranty claims before 90,000 km for pre‑mid‑2020 builds, while UK DVSA MOT data shows low emissions failure rates due to robust Euro 6b compliance. Fuel quality and oil change discipline make long-term reliability highly dependent on owner maintenance habits.
