The Volkswagen CNTC is a 1,395 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, delivering 92 kW (125 PS) and 200 Nm of torque. The integrated exhaust manifold enables rapid warm‑up and reduced emissions.
Fitted to models including the Mk7 Golf, Polo, and T — Cross—specifically the 1.4 TSI 125 variants—the CNTC was engineered for responsive urb…
All production years 2012–2019 meet Euro 6 emissions standards .
The Volkswagen CNTC is a 1,395 cc inline‑four turbocharged petrol engine engineered for compact hatchbacks and SUVs (2012–2019). It combines direct injection (TSI) with a single turbocharger and integrated exhaust manifold to deliver responsive low‑end torque and fuel efficiency. Designed to meet Euro 6 standards from launch, it balances urban agility with highway refinement.

The Volkswagen CNTC was used across Volkswagen's Mk7 and A0 platforms with transverse mounting and shared with SEAT and Škoda under the MQB/MSB architecture. This engine received platform-specific adaptations—revised engine mounts in the T-Cross and modified cooling ducts in the Polo—and from 2017 the Golf Mk7.5 facelift retained the same CNTC code but with updated ECU calibration for WLTP compliance, creating minor software interchange limits. Partnerships enabled SEAT Ibiza and Škoda Fabia to use identical powertrains. 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 CNTC is generally reliable when maintained properly. Its main weakness is the high-pressure fuel pump, which depends on correct oil and fuel quality. With regular 15,000 km oil changes using VW 502 00/504 00 oil and EN 228 fuel, most engines exceed 200,000 km without major issues.
Top issues include HPFP failure due to cam lobe wear, intake valve carbon buildup (common to all direct-injection engines), turbo wastegate rattle, and coolant flange leaks. These are documented in Volkswagen SIBs 2015‑07 and 2017‑12.
The CNTC powered the Golf Mk7 (1.4 TSI 125), Polo (2014–2017), T-Cross (2018–2019), and was shared with SEAT Ibiza and Škoda Fabia under the same 125 PS output. All are Euro 6-compliant from launch.
Aftermarket ECU tuning is common on the CNTC 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 1.4 TSI 125, expect ~6.2 L/100km (city) and ~4.4 L/100km (highway), or about 51 mpg UK combined. Real-world mixed driving typically returns 48–54 mpg (UK), depending on conditions and maintenance.
Yes. Like all modern VW TSI engines, the CNTC is an interference design. If the timing chain were to fail (rare but possible with severe oil neglect), piston-to-valve contact would cause catastrophic damage.
Volkswagen specifies 5W‑30 or 5W‑40 synthetic oil meeting VW 502 00 or 504 00 standards. This is critical for HPFP cam lobe protection. Change every 15,000 km or annually, whichever comes first.
