The Volkswagen CBFA is a 1,390 cc, inline‑four turbocharged petrol engine produced between 2008 and 2015. It features gasoline direct injection (TSI), a single turbocharger, and dual overhead camshafts (DOHC). This compact powerplant delivered 125 kW (170 PS) and 240 Nm of torque, with its turbocharger enabling strong low — rpm pull for responsive acceleration.
Fitted to performance — oriented models like the Golf GT and Scirocco GT, the CBFA was engineered for drivers…
Production years 2008–2015 meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/5679).
The Volkswagen CBFA is a 1,390 cc inline‑four turbocharged petrol engine engineered for sporty compact models (2008-2015). It combines gasoline direct injection (TSI) with a single turbocharger to deliver brisk acceleration and efficient highway cruising. Designed to meet Euro 5 standards, it balances performance with respectable fuel economy.

The Volkswagen CBFA was used across Volkswagen's A5 platform with transverse mounting. This engine received platform-specific adaptations-standardized engine mounts and ancillary layouts for the Golf and Scirocco. All adaptations are documented in OEM technical bulletins.
The CBFA's primary reliability consideration is high-pressure fuel pump (HPFP) wear, with elevated incidence in vehicles subjected to frequent short trips or low-quality fuel. Volkswagen internal service data indicates a notable service rate for this component, while adherence to maintenance schedules significantly reduces failure risk. Using correct fuel and oil makes preventative maintenance critical.
Analysis derived from Volkswagen technical bulletins (2008-2015) and UK DVSA failure statistics (2015-2023). 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 CBFA is generally robust with proper care. Its main long-term concerns are HPFP wear and intake valve carbon buildup, both manageable with preventative maintenance. Using the correct oil (VW 504 00) and premium fuel (98 RON recommended), plus timely replacement of coils and sensors, ensures good longevity. The timing chain is very durable if oil changes are not neglected.
The most frequent issues are high-pressure fuel pump (HPFP) failure, carbon buildup on intake valves, ignition coil pack failures, and faulty coolant temperature sensors. These are well-documented in Volkswagen service literature and owner experiences, with specific technical bulletins available for guidance.
The 1.4 TSI CBFA engine was used in the performance-oriented Volkswagen Golf Mk5 GT (2008-2009) and Mk6 GT (2009-2013), as well as the Scirocco GT (2008-2015). It was the 170 PS variant of the 1.4 TSI family during this period.
Yes, the CBFA responds very well to ECU remapping. A Stage 1 tune can safely increase output to around 200-220 PS and 300+ Nm, utilizing the stock turbo and internals. Further power requires upgraded components like a larger turbo, intercooler, and injectors. Always ensure supporting modifications and maintenance are in place for reliability.
Official combined figures are around 6.5 L/100km (43 mpg UK). Real-world economy varies: expect 8.0-9.0 L/100km (31-35 mpg UK) in spirited city driving and 5.5-6.0 L/100km (47-51 mpg UK) on the highway. Driving style significantly impacts actual consumption, especially given its performance potential.
Yes. The CBFA, like virtually all modern engines, is an interference design. If the timing chain were to fail catastrophically, the pistons would collide with the open valves, causing severe internal engine damage. Fortunately, the chain is very durable with proper maintenance.
Volkswagen mandates oil meeting VW 502 00 or 504 00 specifications, typically SAE 5W-30 or 5W-40. The 504 00 spec is preferred as it allows for extended service intervals and provides better protection for the turbocharger and timing chain. Using non-approved oil can lead to premature wear.
