The Volkswagen CAVC is a 1,390 cc, inline‑four turbocharged petrol engine produced between 2009 and 2015. It features direct fuel injection (TSI), a single turbocharger, and dual overhead camshafts (DOHC). This engine delivered 90 kW (122 PS) and 200 Nm of torque, engineered for responsive urban performance and efficient cruising in compact applications.
Fitted to models such as the Mk6 Golf, Jetta, and Touran, the CAVC was designed for drivers seeking a balance of pepp…
Production years 2009–2015 meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/7890).
The Volkswagen CAVC is a 1,390 cc inline‑four turbocharged petrol engineered for compact hatchbacks and MPVs (2009-2015). It combines gasoline direct injection (TSI) with a single turbocharger to deliver responsive low-end torque and good fuel economy. Designed to meet Euro 5 standards, it balances urban agility with highway efficiency.

The Volkswagen CAVC was used across Volkswagen's A5 platform with transverse mounting. This engine received platform-specific ECU mappings for the Golf, Jetta, and Touran, creating minor software interchange limits. All adaptations are documented in OEM technical bulletins.
The CAVC's primary reliability risk is ignition coil failure on early builds, with elevated incidence in high-temperature operating conditions. Volkswagen internal service data indicated a notable number of coil replacements were performed under warranty, while owner reports frequently cite misfires as a maintenance concern. High engine loads and infrequent spark plug changes can exacerbate coil stress, making regular monitoring critical.
Analysis derived from Volkswagen technical bulletins (2009-2016) and owner-reported data aggregated from manufacturer service networks (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 CAVC is generally a reliable and economical engine. Its main long-term concern is potential ignition coil failure on early production units. With diligent spark plug maintenance, timely oil changes using correct spec oil, and addressing any misfires early by replacing coils, the engine can be very dependable for high mileage.
The most common issues are ignition coil failure (especially on early units), failure of the high-pressure fuel pump, worn spark plugs, and coolant leaks from the thermostat housing or flanges. These are well-documented in VW service information and can be addressed with OEM parts.
The CAVC 1.4 TSI was used in the Golf Mk6, Jetta (A5), and Touran from 2009-2015. Due to VW Group platform sharing, it was also fitted to the SEAT Altea and Škoda Yeti during overlapping production years, always producing 122 PS.
Yes, the CAVC can be safely tuned via ECU remapping. Stage 1 tunes can increase power to around 150-160 PS. The engine's internals are robust, but supporting modifications like an upgraded intercooler are recommended for optimal results. Always use a reputable tuner.
Fuel economy is very good for its performance. Expect around 6.0-7.0 L/100km (40-47 mpg UK) combined in a Golf Mk6. Real-world figures vary with driving style, but it offers an excellent balance of power and efficiency for a small turbocharged engine.
Yes. The CAVC is an interference engine. If the timing chain were to fail (which is rare with proper maintenance), the pistons would collide with the valves, causing severe internal engine damage requiring a costly rebuild.
Volkswagen specifies oil meeting VW 502 00 or 504 00 standards, typically SAE 5W-30 or 5W-40 fully synthetic. Using the correct specification is crucial for protecting the turbocharger and timing chain. Change intervals should not exceed 15,000 km or 1 year.
