The Volkswagen CFWA 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 110 kW (150 PS) and 250 Nm of torque. The integrated exhaust manifold enables rapid warm‑up and improved emissions control.
Fitted to models including the Mk7 Golf, Mk2 Touran, and B8 Passat, the CFWA was engineered for responsive urban driving and effici…
Production years 2012–2014 meet Euro 5 standards; 2015–2019 models comply with Euro 6 depending on market .
The Volkswagen CFWA is a 1,395 cc inline‑four turbocharged petrol engineered for compact and mid‑size models (2012–2019). It combines direct injection (TSI) with a single turbocharger to deliver responsive low‑end torque and smooth power delivery. Designed to meet Euro 5 and Euro 6 emissions standards, it balances performance with urban efficiency.

The Volkswagen CFWA was used across Volkswagen's Mk7/B8 platforms with transverse mounting and shared within the Volkswagen Group. This engine received platform-specific adaptations—revised cooling ducts in the Golf and modified engine mounts in the Passat—and from 2016 the updated HPFP and ECU calibration, creating minor service part distinctions. Partnerships enabled use in Škoda and SEAT models under different engine codes. 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.
Analysis derived from manufacturer technical service bulletins and industry workshop records. Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The CFWA is generally robust with proper maintenance. Early units (2012–2015) had HPFP concerns, largely resolved by 2016 updates. Using RON 95+ fuel and VW 502 00/504 00 oil significantly improves longevity. Chain-driven timing means no belt changes, aiding reliability beyond 200,000 km in well-kept examples.
Top issues include high-pressure fuel pump wear (pre-2016), intake valve carbon buildup due to direct injection only, turbo actuator sticking, and minor oil leaks from cam cover/sump. These are documented in Volkswagen service bulletins STB 2015‑07 and STB 2016‑12.
The CFWA powered the Golf Mk7 (1.4 TSI 150 PS), Passat B8, and Touran II from 2012–2019. It also appeared in Škoda Octavia III and SEAT León Mk3 under the CZCA code, sharing core architecture but with minor calibration and mounting differences.
Aftermarket ECU tuning is common on the CFWA 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 150 PS, expect ~7.2 L/100km (city) and ~4.9 L/100km (highway), or ~48 mpg UK combined. Real-world mixed driving typically returns 44–50 mpg (UK), depending on conditions and maintenance. Efficient at motorway speeds due to low engine load and tall gearing.
Yes. The CFWA is an interference engine. If the timing chain were to fail (rare but possible), piston-to-valve contact would cause catastrophic internal damage. However, the chain is designed as maintenance-free and generally reliable if oil quality is maintained.
Volkswagen specifies SAE 5W‑30 or 5W‑40 synthetic oil meeting VW 502 00 or 504 00 standards. Never use older 501 01 oils. Change every 15,000 km or 12 months to protect the turbo, HPFP, and timing chain from soot and wear.
