The Volkswagen CDLC 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. Its compact turbocharged design enables responsive urban drivability with reduced fuel consumption compared to larger naturally aspirated units.
Fitted to models such as the Mk7 Golf, Polo, and T — Cross, the CDLC was en…
All production years 2012–2019 meet Euro 6 standards .
The Volkswagen CDLC is a 1,395 cc inline‑four turbocharged petrol engineered for compact hatchbacks and SUVs (2012–2019). It combines direct fuel injection (TSI) with a single turbocharger to deliver strong low‑rpm torque and efficient urban driving. Designed to meet Euro 6 emissions standards from launch, it balances entry‑level performance with regulatory compliance.

The Volkswagen CDLC was used across Volkswagen's Mk7/A0 platforms with transverse mounting and shared within the Volkswagen Group for entry‑level applications. This engine received platform-specific adaptations—revised engine mounts in the Polo and compact intercooler routing in the T-Cross—and from 2016 the Golf received HPFP cam follower updates, creating minor interchange limits. Partnerships enabled Škoda's 1.4 TSI and SEAT's 1.4 TSI to share core architecture. 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 CDLC is generally robust when maintained properly. Early units (2012–2015) had HPFP cam follower concerns, but post-2016 revisions improved durability. Regular oil changes with VW 502 00/505 00 oil and use of 95 RON (preferably 98 RON) petrol greatly enhance longevity. Many examples exceed 180,000 km with no major issues.
Top issues include HPFP cam follower wear (especially pre-2016), intake valve carbon buildup due to direct injection, GT12 turbo actuator faults, and PCV system leaks. These are documented in Volkswagen SIB 2015‑09 and TIS service notes.
The CDLC powered the Golf Mk7 (2012–2019), Polo Mk5 (2014–2017), T-Cross (2018–2019), and was also used in Škoda Fabia III and SEAT Ibiza Mk5. It was exclusive to 125 PS 1.4 TSI variants and not used in 140 PS or 150 PS derivatives.
Aftermarket ECU tuning is common on the CDLC 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.
Real-world consumption is ~7.2 L/100km (city) and ~5.1 L/100km (highway), or about 40 mpg UK combined. Conservative driving can achieve mid-40s mpg UK; aggressive use drops to low 30s mpg UK.
Yes. The CDLC is an interference engine. If the timing chain fails (rare but possible with severe oil neglect), piston-to-valve contact can cause catastrophic damage. However, the front-mounted chain is highly durable with proper maintenance.
Volkswagen specifies 5W‑40 synthetic oil meeting VW 502 00 (petrol) or 505 00 (diesel-compatible) standards. Always use this specification and change every 15,000 km or annually to protect the turbo, HPFP, and timing system.
