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 p…
All production years 2016–2023 meet Euro 6b emissions standards .
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 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.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.

The most common questions about engine codes, what they mean, how to find them and how this database works
The CKTC is generally robust when maintained properly. Early units (2016–mid-2020) had HPFP cam lobe wear concerns, but post-update engines are more durable. Using RON 98 fuel and adhering to 15,000 km oil changes with VW 504 00/507 00 spec oil significantly improves longevity. The timing chain is maintenance-free and rarely problematic.
Most documented issues are HPFP drive lobe wear (pre‑2020), turbo wastegate rattle, PCV diaphragm failure, and coolant flange leaks. These are covered in VW service bulletins. Carbon buildup is minimal due to direct injection.
The CKTC powered the Golf Mk7.5 (1.5 TSI 150 PS), T-Roc (1.5 TSI 150 PS 4Motion), and Škoda Karoq (1.5 TSI 150 PS) from 2016 to 2023. It was not used in SEAT or Audi under this code—those brands used related but distinct EA211 Evo variants.
Aftermarket ECU tuning is common on the CKTC platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
In a Golf Mk7.5, expect ~6.5 L/100km (city) and ~4.4 L/100km (highway), or ~52 mpg UK combined. The T-Roc 4Motion is slightly thirstier at ~7.1 L/100km city. Real-world economy depends heavily on driving style—aggressive use can push consumption above 8.8 L/100km.
Yes. Like all modern VW TSI engines, the CKTC is an interference design. If the timing chain fails (extremely rare), piston-to-valve contact will cause catastrophic damage. However, the chain is front-mounted and designed for life-of-engine use with proper oil maintenance.
Volkswagen specifies SAE 5W‑30 oil meeting VW 504 00 (petrol) or 507 00 (diesel-compatible) standards. Always use fully synthetic oil approved to these specs and change every 15,000 km or 12 months to protect the turbo, HPFP, and camshaft.
